APPENDIX 1 242
 MESSAGE FROM THE CHAIRMAN
Nigeria has had a long history of census taking. The first census was in 1871. The
censuses of 1871, 1886 and 1896, were restricted to Lagos Island and parts of Lagos
Mainland. The censuses of 1901, 1911 and 1921 covered a few more urban towns in the
colony. Most of these censuses were actually population estimates. Although the
Census of 1952/53 was elaborate in organisation, its non-simultaneity, which had
implications for possible double counting, is considered its weak point.

The first post-independence census in Nigeria was carried out in 1962. This was
out-rightly cancelled and another conducted in 1963. The 1963 census results became
o cial figures and were used until 1991 census results were accepted. There was a
census in 1973 but the results were declared unacceptable on account of massive
inaccuracies. The 1991 census broke the myth of failed censuses in Nigeria.

A Population and Housing census have several uses to a nation. It provides the total
number of persons and housing types and their characteristics in every town, village
or/and locality. This information provides data for planning programmes in education,
health, housing and other social services at all levels of governance. In addition to its
use by the government, information derived from the census helps the
business/private sector to plan their activities.

To conduct the 2023 population and housing census, the Commission is adopting the
Computer-Assisted Personal Interviews (CAPI) data collection method; all major
questionnaires and several other forms are embedded in the Personal Digital Assistant
(PDA) that will be used. These questionnaires will be administered on all living
(dwelling) quarters and person’s resident in Nigeria at the time of the census. It will be
administered only in selected Enumeration Areas (EAs). These questionnaires will be
administered with the use of Personal Digital Assistant (PDAs) devices.

The Commission getting this far with the 2023 PHC would not have been possible
without the various technical support and strong commitment of some International
and local institutions led by the UNFPA and would like to extend our sincere
appreciation to all of them.

This manual is designed to guide you on how to administer both questionnaires and
other census forms. It is also the main training material. I implore all enumerators to
participate fully in the training programme and to always refer to this manual
whenever they have issues that need clarification.

 PREFACE
The Field O cer’s Manual of Instruction was researched, compiled, developed,and
produced by the National Population Commission (NPC) through the collaborative
e orts of the 2023 Census Management Team, NPC Sta (serving and retired), the
Academia, International Agencies and other Stakeholders. This Manual took several
months to develop over a dozen collaborative meetings and training exercises.We
are now at a stage in the history of Nigeria where another Population and Housing
Census (PHC) is being planned for March/April 2023. The unique thing about the
2023 census is that it will be the first time that Nigeria will be conducting a “digital”
and “paperless” census, through the deployment of the latest technology in
population data collection all over the country with the use of Personal Data
Assistant (PDA)/Tablet.
The Manual is made up of twenty-two Chapters that are carefully selected to
explain all legal frameworks, concepts, methods, strategies, techniques, procedures
and challenges for the 2023 PHC. The chapters in the manual are so arranged in
sequential order as each chapter dovetails into the other to allow for easy
appreciation of ideas as one progresses. The manual is meant for Census
Functionaries as the main material to be used during the training of facilitators and
enumerators and as reference material during the conduct of building numbering
and household listing and for actual enumeration. The manual introduced Field
Sta and Functionaries to various techniques of collecting demographic,
socio-economic and household facilities data during Population and Housing
Census. Topics covered in this Manual were carefully designed to assist all
categories of Census Functionaries on both internationally and nationally
acceptable ways of conducting census and collection of all information as the case
may be. While acknowledging local peculiarities, the Manual richly drew resources
from the United Nations (UN) Principles and Recommendations for conducting PHC
in the 21st Century.
The Manual has added new concepts and topics to meet the present and future
needs of the country in terms of population and housing data. Experts will find a
blend of robust concepts in simple narrative and grammar, very friendly. Census
functionaries must know that the success of the 2023 PHC will depend on our
careful understanding of the content of this manual and the application of it to the
latter. We must resist the temptation to embellish or modify the contents of this
manual so as to guarantee universal application of it all over the country.
I find this manual of instruction a reference material and a source of invaluable
information on census processes and procedures. I appreciate the time put in
developing this manual and the contents therein, which to me is a reflection of the
commitments of the Census Management Team. I invite all of you to make this
Manual a dependable ally and to devote time to go through it at all times.

 ACKNOWLEDGEMENT
We have taken a lot of e ort into this work. However, completing this
assignment would not have been possible without the support and guidance of
a lot of individuals. We would like to extend our sincere thanks to all of them.
Particularly, we express our deep appreciation to the executive Chairman,
National Population Commission Hon. Nasir Isa Kwarra, Dr Ipalibo M. Harry,
Chairman, Census Standing Committee, all Honourable Federal Commissioners
and the Director General, Dr Osifo Tellson Ojogun for their tireless e ort in
ensuring that the dream for a digital census in Nigeria comes true.
Also worthy of appreciation, is the technical and intellectual advice provided by
the UN Chief Technical Adviser to the Commission on 2023 Population and
Housing Census, Dr Collins Opiyo MBS. His constant guidance has kept the
whole process on track and full of innovation. While the untiring e orts and
commitment of the Census Manager, Dr Inuwa Jalingo, towards realisation of
2023 PHC is highly commendable.
This manual of instruction which is basically prepared as a user's guide on the
PHC protocol would have been an unending task but for the dedication of the
Census Directorate and Sta who have all remained committed to the vision to
actualize the conduct of 2023 PHC.Therefore, in the executing this work I would
like to sincerely appreciate the followings; Abubakar Bello Afegbua, Muhammad
Dakayawa Kassim, Elibe Charity Ekwutosi, George Odunaike Temitope, Bolaji
Bolarinwa Olarenwaju, Musa Pius Shekarah, Oluwaseun Ajayi, Adebayo Olayide
Ajani, Ezekwe Harrison Tabansi,Titilayo Hammed , Victo Aisaborhale, and all
other sta of the department.
This manual is unique in many ways being the first time Nigeria is conducting a
fully digital census and so it's a rich collection of literature and practical
illustrations of concepts, definition of terms and procedures, making the
document a user friendly guide. The preparation of this manual spans over
some years and stages of reviews in the hands of many professionals including
those of our sister departments and our retired but not tired colleagues. To this
end I would like to appreciate the department of Cartography, Information and
Communication Technology, Planning and Research Departments and Public
a airs among others. Also our former and outgoing colleagues particularly, Mr
Usman Kolapo, Datsu Kalep, Ladan Maiakwai, Fasiku David, Chidi Arukwe Amah
JJ, Olasoji Adewale, Chike Moronu, Erebi Robunson, Sanni Gar, Makinwa Martins
O., Dr. Musa Sani Zakirai and all teams that have immensely contributed to this
piece of work
Again, I wish to state that the development of this edition of the Census
instrument went a step higher by actualizing the long envisaged collaboration
with the academic community. The involvement of the academia at the level of
reviews and finalisation of the questionnaire and this manual introduced a new
dimension of quality which we do not wish to take for granted and so we
acknowledge the Population association of Nigeria (PAN) for facilitating the
engagement and all academia who have not regarded our lean allowances but
have taking up the task committedly.
Finally, we also acknowledge the painstaking e orts of our consultants on the
applications for data collection, Taslim Olawale Salaudeen (CensusPAD) and Mr.
Adekanmbi Taiwo Olasupo (CSENTRY).
This census manual is designed to meet the needs of all census functionaries in
terms of roles, responsibilities, rules and basic guidelines that will support the
conduct, execution and delivery of the 2023 Population and Housing Census. I
enjoin all functionaries to make it a close companion all through the census
programme.

 CHAPTER ONE
INTRODUCTION

1.1 History of Census taking in Nigeria

Population and Housing Censuses (PHC) are the foundation of statistical
systems, providing benchmark statistics of a country’s population and housing
stock, and baseline information to produce other statistics. Census was first
conducted in the area known today as Nigeria in the year 1866 by the British
colonial government within the Colony of Lagos. There were also decennial
censuses conducted only for Lagos Colony in the years 1871, 1881 and 1901
respectively. Ten years later in 1911, the census exercise covered the Southern
Protectorate including Lagos. The 1911 census-taking had a wider coverage as it
involved the whole of Southern Nigeria. This was possible because in 1906, five
years before the census, Lord Fredrick Lugard who was the Governor-General
of Nigeria merged the Lagos Colony with the Southern Nigeria Protectorate.
The amalgamation of the Southern and Northern Nigeria Protectorates in 1914
by Lord Lugard and the enactment of a Census Ordinance in 1917 brought
remarkable changes to the conduct of censuses in Nigeria as it paved the way
for the conduct of the first nationwide census in 1921.
The next census was in 1931, which was the second nationwide census that was
not comprehensive in its coverage. This was because only six towns including
Lagos and 201 villages spread across the country were covered. Estimates from
existing tax records were used in compiling the figures of other places. The 1931
census was a ected by the world economic depression and the numerous tax
riots in Calabar and Owerri provinces in the then Eastern region. The situation
prevented enumeration in the major towns of these areas. In some parts of the
Northern Provinces, locust invasion resulted in the diversion of some census
sta to perform locust control duties.
In 1941, the census did not take place because of the Second World War. The
census exercise resumed with the conduct of the 1951/53 census after the
Second World War. The census in Northern Nigeria was conducted between
May and July 1952 while it was conducted in the West and Midwest in December
1952 and January 1953. In the Eastern part of the country, the census was
conducted from May to August of 1953. The lack of universality and
simultaneity of the census taking made it di cult to aggregate the census data
nationally.

Page | 1
Four post-independent censuses were conducted in 1963, 1973, 1991 and 2006.
The 1973 census was however cancelled. The first Census that integrated the
housing component was conducted in 2006, during which persons and housing
units were enumerated. The 2006 Census put the total population of Nigeria at
140 million.
The Nigerian 2023 Population and Housing Census consists of a population
census and a housing census as one operation. The fieldwork commences on
5th February with Building Numbering and Household LIsting, while actual
enumeration will start on 28th March, 2023. Enumeration will end on 2nd April,
2023.
Population Census entails the complete enumeration of all persons and Housing
Census entails the complete enumeration of all living quarters and their
characteristics, within Nigerian borders at a specified time. The information on
the population and the housing characteristics can be readily matched and
processed for analysis. This makes it possible to relate the housing census data
to the information on demographic, social and economic characteristics of each
household member that is collected in the population census.This data will form
a baseline for economic planning and national development.

1.2 Importance of the Population and Housing Census

The Population and Housing Census (PHC) will provide key information about
persons, households, buildings, buildings, localities, and the nation. The PHC
gives information about:
1. population characteristics;
a. age and sex;
b. living and working conditions;
c. distribution across the country, states, local government areas,
localities and by urban/rural areas;
d. marital status, educational attainment; employment status; type
and nature of jobs;
2. household and housing characteristics including conditions of housing,
structural characteristics, sources of drinking water, sources of energy
etc.;
3. availability of facilities such as schools, health, ICT, financial institutions,
etc.

Page | 2
1.3 Essential Features of a Population and Housing Census
The essential features of a modern Population and Housing Census
recommended by the United Nations (UN) are:
1. Individual enumeration: each individual and each set of living quarters is
enumerated separately and the characteristics thereof are separately
recorded.
2. Universality within a defined territory: every person present in and/or
residing within a defined territory at a specified time will be enumerated.
3. Simultaneity: this requires that each person and each set of living
quarters be enumerated within the same reference period.
4. Defined Periodicity: censuses should be taken at regular intervals. A
series of censuses makes it possible to appraise the past, accurately
describe the present and plausibly estimate the future.
5. Capacity to produce Small-area Statistics: census should produce data
on the number and characteristics of the population and housing units
down to the lowest appropriate geographic level of the country, and for
small population groups.

The census must refer to a specific point in time (generally referred to as

the Census Night) and a well defined reference period,.
For the 2023 PHC, the Census Night is 00:00 hour (midnight) of 28th March,
2023 and the Census Reference Period starts from the 00:00 hour
(midnight) of 28th March, 2023 and ends on 23: 59 hours of 2nd April, 2023.

This assumes that all persons should have been enumerated at midnight of
29th, March 2023. The Census Night will be publicised in advance throughout the
country so that it will be easily remembered by everyone

1.4 Persons to be enumerated during the 2023 PHC

The following persons should be enumerated during the 2023 PHC:
a. only persons who are physically present at the time of the Enumerator’s
visit and have not been enumerated elsewhere;
b. all Special Population groups- required to be enumerated on census
nights such as persons on transit;
c. all persons including guests who spent the previous night in a regular or
institutional household;
d. usual members who were temporarily absent during the previous night in
a household because of the nature of their work such as night watch
men, security men, doctors, nurses, fishermen etc;
Page | 3
 e. guests who did not spend the previous night but are not going back to
their usual residence before the end of the census period;
f. all homeless persons; and
g. all Census Functionaries.

1.5 Persons not to be enumerated during the 2023 PHC

The following persons should not be enumerated during the 2023 PHC:
a. all guests or non-usual residents who did not spend the previous night in
a household but are going back to their usual residence before the end of
the census period;
b. all persons born after completion of enumeration in the household ; and
c. all persons who died the previous night before the arrival of the
enumerator's in the household.

1.6 New features in the 2023 Census

The following are some of the new features in the 2023 PHC:
a. The use of Computer-Assisted Personal Interviewing (CAPI) to ensure
e cient data, collection, management, and processing. This will help to
receive real-time data and also minimise the data processing period so
that processed data could be released shortly after field data collection.
b. The use of Geographic Positioning System (GPS) to capture the location
(coordinates) of all structures. This allows for geo-fencing of enumeration
areas i.e. enumerators cannot work outside of their enumeration area.
c. Three new modules have been introduced into the 2023 census which are:
■ ICT
■ Fertility and Child Survival
■ Mortality (Deaths in the Households in the last 12 months)
■ Di culties in performing activities
■ Sanitation

1.7 Key points to note

Population and Housing censuses are key demographic and socio-economic
data sources for any country. The 2023 Census will be carried out in the 774
Local Government Areas of the country. Your appointment as a Census
Functionary in the conduct of the Census is a privilege for you to contribute
towards collecting reliable data for the purpose of development planning in
Nigeria.

Page | 4
This manual of instructions will be your reliable helper as you do your work. You
should always take it along when you are enumerating because you will need it
any time you are in di culty. International best practices in conduct of
Censuses and Surveys requires that the rules, regulations, guidelines and
principles behind the project are followed in a uniform and simultaneous
method to avoid di erences and variations in the conduct of the exercise.

 CHAPTER TWO
LEGAL FRAMEWORK, ORGANISATION AND MANAGEMENT
This chapter will describe the legal framework, and organisational and
management structure under which the 2023 PHC will be conducted. At the end
of this chapter, field functionaries should have understood the following:
1. Legal provisions for 2023 Census
2. National Population Commission’s o ces and functionaries
3. Census materials to be used
4. Working hours and duration of enumeration
5. Behaviour expected of all functionaries
6. Visit to community leaders
7. Security Management
8. Duties of all census functionaries
2.1 Legal Provisions for 2023 Census
The constitution of the Federal Republic of Nigeria provides for a periodic
nationwide census in the country. The work of functionaries is empowered by
law which allows them to enter any premises or compounds within reasonable
hours of the census reference period for the purpose of enumerating persons
and structures. This authority should however be used with caution, that is,
you must abide by the rules and regulations set for the conduct of the
census.

2.1.1 Statutory Requirements

The National Population Commission Act, Cap 67 of 2004 empowers the
Commission to conduct the Population and Housing Census of Nigeria in

 CHAPTER THREE
CODE OF CONDUCT AND RESPONSIBILITIES
The aim of this chapter is to make all field functionaries aware of their conducts
and responsibilities during the 2023 population and housing census.

3.1 Confidentiality of Census Information

The information you obtain is CONFIDENTIAL and shall only be used to compile
statistics. The law places a restriction on publishing particulars of individuals
and that all data are published as numerical tables, summaries and general
conclusions. You are not permitted to disclose any information to anyone who is
not an authorised o cer, nor should you leave the information where others
may have access to it. Disclosure of any information obtained in the Census
without lawful authority is an o ence liable to punishment (see Census
O ences).
You will administer the questionnaire using the CAPI. On no account should you
allow any unauthorised person(s) to use your tablet or any of the Census forms.
All the Census information you receive must be kept confidential. Under no
circumstance must you reveal any information to anyone unless he/she is a
sworn employee of the National Population Commission (NPC) and is
authorised to collect such information for o cial purposes.

3.2 Oath of Secrecy

To enforce this confidentiality, all functionaries will be required to take an oath
of secrecy during training (see appendix). In the oath-taking, functionaries will
promise to fulfil their duties faithfully and honestly and will promise not to
disclose any information which comes to their knowledge to unauthorised
persons. Functionaries will also promise to comply or abide by the rules and
instructions given by the Commission in the execution of the exercise. The Oath
of Secrecy is a veritable tool in this regard. The Section 30 (2) of the NPC Act,
provides inter alia:
“Every member of sta of the Commission employed in the execution of any
power or duty under this Act shall, before entering upon his duties, make and
subscribe to an oath before a magistrate, in the form set out in the Second
Schedule to this Act.”
It is therefore a legal requirement for functionaries to take the oath before
assuming their duties during census.

Page | 16
3.3 Census O ences and Penalties

Considering the above cited Act, it will constitute an o ence for any functionary
to work at cross purposes with the objectives of the Commission. It is for this
reason that Under Part V of the NPC Act, o ences are specified and penalties
are provided for, and they include:
Section 18: Prohibition of debate of census and other population figures without
due authority;
Section 19: falsification of returns;
Section 20: Unlawful disclosure and failure to furnish information lawfully
requested;
Section 22: Unlawful obstruction during census;
Section 23: Destruction of documents;
Please note that these are the general o ences which may be committed by
either persons employed as functionaries or by a member of the general public.
Nevertheless, these o ences carry punishments ranging from fines to
imprisonment/jail terms.
Beyond these general provisions of the NPC Act, there are other o ences which
may be committed by functionaries during the Census in relation to the Public
Services Rules. Further, Rules 030301 and 030402 provide for certain
misconducts which warrant punishment, and these include: dishonesty,
negligence, falsification of records, suppression of records, divided loyalty, etc.
The Census o ences include:
a. failure to use the methodology provided and adopted by the Commission
for the Census exercise;
b. tampering with Census materials without authority;
c. forging, falsifying or manipulating Census data;
d. failure to report to the superior o cers anything observed on the field or
in the course of duty that may be against the interest of the Commission;
e. working at cross purpose with the objectives of the Commission;
f. disclosing to the public, information lawfully obtained in the course of
duty;
g. taking decisions independently without recourse to superior o cers;
h. involvement in political activities while in the employment of the
Commission;

Page | 17
 i. failure to disclose to the Commission through the superior o cers,
information obtained in the course of duties, which information is useful
to the Commission;
j. any other act inimical or detrimental to the interest of the Commission
and the conduct of the entire census exercise.
Therefore, where these rules are infringed upon, the Commission will not
hesitate to invoke the disciplinary provisions therein to punish o enders,
especially where it involves sta of the Commission (permanent and adhoc
sta ). And in the case of non-sta , they will be handed over to the law
enforcement agencies for immediate prosecution under relevant laws.
All functionaries are thus advised to be conscious of their actions and activities
throughout the census exercise and avoid being caught by the law. Ignorance of
the law is not an excuse!

 CHAPTER FOUR
SAY NO TO SEXUAL EXPLOITATION, HARASSMENT AND ABUSE

4.1 Introduction
Sexual Exploitation, Harassment and Abuse (SEHA) has many dimensions and
manifestations, that happens mostly in workplace or learning environment and
often with women and girls as victims. Practically, “Sexual Exploitation,
Harassment and Abuse entails unwelcome sexual advances, requests for sexual
favour and other verbal, non-verbal or physical pestering or conduct of sexual
nature against the opposite sex”. For the 2023 Population and Housing Census
(PHC), it is likely to occur during the various phases/locations of training or
during the field conduct of the main head count. Perpetrators are likely to be
those at leadership positions at these levels.
4.2 Sexual exploitation
Sexual exploitation means any actual or attempted abuse of a position of
vulnerability, di erential power, or trust, for sexual purposes, including, but not
limited to, profiting monetarily, socially, or politically from the sexual
exploitation of another.”

4.3 Sexual abuse

means the actual or threatened physical intrusion of a sexual nature, whether
by force or under unequal or coercive conditions.”
In that regard, every unwelcome sexual advances/conduct/ insinuations/
suggestions by the person subject is/should be considered unacceptable and
resisted. Such conduct breeds unreasonable interference with an
individual's/teamwork performance and could create an intimidating, hostile, or
o ensive working environment, which at the long run could a ect the quality of
data collection and jeopardise the entire field exercise.

4.4 About SEHA module

Completing the course on prevention of Sexual Exploitation, Harassment and
Abuse (PSEHA) is mandatory for all NPC personnel including sta , consultants,
individual contractors, stand-by, ad-hoc and other persons who work for the
NPC on the 2023 PHC. Personnel of other government entities. CSOs and
academia associated with the NPC will also be trained on the SEHA.
The aim is to raise awarenessl about how acts of sexual exploitation,
harassment and abuse impact individuals and whole communities and what to
Page | 19
do about it. The knowledge gained will support e orts to prevent and combat
sexual exploitation, harassment, and abuse. The course also explains
responsibilities of reporting allegations of sexual exploitation and abuse. The
training focuses on specific responsibilities and accountability of census
managers and personnel. NPC senior management at national, State and Local
government levels are requested to make sure that all personnel and partners
participate in the training session on PSEHA.
This training is composed of a set of lessons designed to raise your awareness
about PSEHA, become familiar with a range of measures to combat SEHA,
understand what the impact of SEHA on victims is and the consequences for
NPC personnel and partners who commit SEHA.
Through discussion, examples and case studies, the training will familiarise
census o cials with the Standards of Conduct on SEHA and their obligations to
uphold these standards, what they can do to prevent SEHA and how to report
such abuses by NPC personnel. If you are a census manager (Head of O ce /
Head of Department), you will learn about additional responsibilities to enforce
the standards of conduct.

4.5 What constitute sexual harassment?

i. Unwanted attention, including touching or physical contact
ii. Requests for sexual favour or making conditions for participation
in the census work, selection and posting based on sexual Favour.
iii. Unwelcome sexual advances through text messages, emails or
conversations
iv. Intimidation due to refusals to succumb to sexual advances v.
Making vulgar or sexual jokes, among others

4.5.1 Sexual Harassment During 2023 Census

Globally, sexual harassment is condemned in the strongest terms, unacceptable
and punishable by law in many countries, including Nigeria. For the entire
census process, there will be zero tolerance for all forms, dimensions, and
manifestations of sexual harassment. Accordingly, any functionary, irrespective
of their participatory position or level (whether an NPC sta or ad-hoc) caught
engaging in this act directly or indirectly, shall be dismissed (without pay) from
the census work/operations. Also, functionaries are encouraged to report all
forms of sexual harassment/ experiences to the Hon. Federal Commissioner at
the State level and or the Census Manager at the headquarters with leading
information on the perpetrator(s).
Page | 20
Therefore, all personnel that will be involved/engaged in the 2023 PHC should
resist engaging in all forms of sexual harassment through-out the exercise to
safe-guard the integrity at workplace and quality of data collection.

4.5.2 Why does it matter?

1. Sexual Exploitation, Harassment and Abuse (SEHA) violates fundamental
human rights and is a betrayal of the core values of the 1999 Constitution
(sections 34 and 42), Criminal Code (sections 351, 352 and 360), Panel
Code (sections 281, 282 and 285) and United Nations.
2. SEHA undermines the e ectiveness of the government or United Nation’s
work and the trust of the most vulnerable populations we are mandated
to protect.
3. SEHA has serious consequences for the individuals and communities
a ected. SEHA harms victims physically, emotionally, psychologically,
and socially.
4. SEHA compromises sta performance and achievement of Census
objectives (i.e. adversely a ects the quality of the Census results).

4.5.3 Zero Tolerance:

NPC acknowledges and agrees that the organisation will apply zero tolerance
regarding SEHA by census personnel including ad-hoc sta

 2. Exchange of money, employment, goods, or services for sex, including
sexual favour or other forms of humiliating, degrading or exploitative
behaviour. This includes exchange of assistance that is due to
beneficiaries.
3. Sexual relationships between sta of NPC or its partners, associated or
related personnel and beneficiaries of assistance. Such relationships are
strongly discouraged, since they are based on inherently unequal power
dynamics and undermine the credibility and integrity of the work of NPC.

 CHAPTER FIVE
DUTIES AND RESPONSIBILITIES OF ENUMERATORS
This chapter elaborates on the duties and responsibilities of enumerators in the
2023 PHC.

5.1 Working Hours and Duration of Enumeration

Enumeration in the 2023 Population and Housing Census will be conducted

within the census reference period. This is the zero hour of 29rd March, 2023 to
zero hour of 3rd, April, 2023. Enumeration should not commence before the
midnight of the first census day, or continue after the expiration of the census
reference period.

Enumerators must arrive at the EA immediately after training for

updating, building numbering, and household listing exercises. During the
census, you will work until enumeration of all households in the EA(s)
assigned to your set is completed.

It is essential that enumerators visit all households in their assigned EA and

enumerate all members physically present within the census reference period.
Therefore, enumerators should not stay longer than necessary in any
household or with any individual. They will have to work outside the normal
working hours during the enumeration period. They should work hard to
complete their assignment during the Census Reference Period. If it becomes
obvious that they cannot finish on time, they should report the matter as soon
as possible to their Field Supervisor. But, under no circumstance should
enumerators stop working until they have completed enumeration in the whole
Enumeration Area. Enumerators must also not observe any fixed working hours.
They will have to work longer than usual since some respondents or entire
households are only available at certain hours of the day. The use of call back
cards will assist them in covering these persons. Enumerators are to give their
best in order to finish the enumeration within the census reference period.

5.2 Enumerator DOs and DON’Ts

As an Enumerator, it is expected that you possess team spirit which is necessary
for a successful enumeration. You and your colleague enumerator form an
enumeration team, however, in some cases, you may be required to work alone.
Both of you have equal responsibilities and functions and will be assigned one
PDA for the enumeration.
Page | 25
You will work under the guidance and supervision of the Field Supervisor and
bring to his/her notice all di culties and problems which may arise in the field.
In cases where the Field Supervisor cannot resolve the issue, s/he will contact
other senior field o cers. Before the close of training, you will know your
supervisor and the colleague enumerator.
As an enumerator you are required to:
a. attend all training sessions regularly and punctually; study the manual of
instructions carefully and understand it thoroughly; keep the manual
under study and seek guidance from it at all times. If any part of the
instructions is not clear, seek advice and assistance from your Field
Supervisor.
b. obtain the materials as listed in Table 1 from your Field Supervisor and
report promptly to the Field Supervisor when running out of materials or
there are issues with the Personal Digital Assistant.
c. check the digital map and boundaries of your EA before you leave the
training centre after the completion of your training.
d. ensure that your map and attributes match your area of assignment
after locating the Enumeration Area.
e. visit all fully and partially occupied buildings in the EA, number them and
list all their households.
f. paste or display the census posters provided to you in conspicuous
places in the EA.
g. create good relationships with household heads and their members.
h. you should avoid discussions on politics, religion and security matters
during enumeration. Team spirit is necessary for successful enumeration.
i. respect the culture and customs of the area that you are working;
j. ensure correct and complete entering of information supplied in the PDA
k. complete all other census documents or forms supplied to you
l. ensure that questionnaires are duly completed as per instructions before
streaming to the central server and before final submission of equipment
to the Field Supervisor.
m. ensure the safety of all census materials in your care as well as your
personal security. It is important that your ID card is with you at all times.
n. in cases where you notice security issues or suspicious activities, report to
your Field Supervisor immediately;
o. ensure that you do not avail your census materials to unauthorised
persons;

Page | 26
 p. assist in every aspect of census operation whenever you are called upon
by your Field Supervisor.
q. drop a callback card where there are persons that are not available at
the time of your visit, and ensure that you revisit the household;
r. you should complete enumeration of all households in your EA. Under no
circumstance should you leave an interview in any household
uncompleted. Where this is unavoidable despite several callbacks, bring it
to the notice of your Supervisor as soon as possible before the
enumeration ends.
5.3 Expected Behaviour

An enumerator is considered to be a responsible, qualified and honest citizen of

Nigeria. Therefore, you should act as a good ambassador of your community
and the nation at large. You must be patient in any di cult situation, because
showing emotion may harm the entire operation. You must avoid discussions on
politics, religion and security with members of the public once you are on the
field. Although public awareness and advocacy have been made to elicit the
cooperation of the people prior to this time, the success of the census will
depend upon how well you relate with your respondents.

5.4 Visit to Community Leader(s)

On arrival at the locality of assignment, an enumerator led by the supervisor
should visit the community leader. Do not assume that the community leader
should have heard of your coming. Some village heads may not have heard.
Therefore, before any commencement of work in the EA your team should
a. call on the village head and elders.
b. make yourself and your mission known to the community leader and
politely ask for cooperation and assistance.
c. be well mannered and friendly.
d. not create panic, fear or misunderstanding.
e. wear simple cloth that is acceptable with the culture of the locality of
assignment.

5.5 Household Entry

An enumeration team should pay a visit to community leaders to explain their

mission. After obtaining permission from the community leader, the team will
then proceed to their EA of assignment. At this stage, enumerators must ensure

Page | 27
that they observe and respect all the rules and customs governing visits to
other peoples’ homes in the area of assignment. For example:

‘Knock before you enter and greet persons you meet in the customary
way with a smile. Ask for the head of household or any adult member of
the household and explain the purpose of your visit’

You may, for instance, introduce yourself as follows:

‘Good morning (Afternoon or Evening depending on the time of the day).

Sir/Madam, you may have heard of the Population and Housing Census that
is currently taking place throughout the country. I am a Census Enumerator
(produce your identity card if required) and my work is to number the
buildings, list the households and enumerate every person in this area. The
information you give me shall be kept strictly confidential. The data collected
in the Census will be helpful in the formulation of policies and planning for the
welfare of the people. I will not take much of your valuable time.
Can we commence the interview now?

Communication between you and the respondents must be in the language that
is understood by you and the respondents. Where a respondent does not speak
any language you understand, any member of the household or neighbour with
the approval of the respondent, may help. Where no member of the household
can assist and your respondents do not want help from their neighbours,
consult your Field Supervisor as soon as possible. Your Field Supervisor would
either ask another enumerator to assist you or may arrange for an interpreter
if required.
5.6 Interviewing Techniques for Census

Data for the 2023 PHC will be collected by means of face-to-face interviews
with respondents. It is therefore appropriate to acquaint Enumerators with
some interviewing techniques. The enumerators should be aware that the whole
exercise of conducting a National Census is dependent on how well they
interact with the respondents. This section is devoted to discussing how
Enumerators would e ectively elicit responses from the household respondents.

5.7 Retrieval of Documents

At the end of enumeration, the PDAs and other instruments are retrieved from
functionaries. The materials provided to them must be accounted for. A retrieval

Page | 28
form will be used to clear functionaries o the field. Functionaries will have to
sign a digital form to return their materials , which include:
a. personal Digital Assistant (PDA)
b. charger
c. power Bank
d. unused stickers
e. other sensitive documents used and unused during enumeration.
f. unused call back cards

Page | 29
 CHAPTER SIX
DUTIES AND RESPONSIBILITIES OF FIELD SUPERVISORS

6.1 Overview
The main thrust of conducting a national census is to produce accurate, reliable
and acceptable socio-demographic and economic data for planning purposes
in critical areas like education, health, employment, etc. You are therefore
expected to play an important role especially during data collection, the most
crucial phase of implementing the exercise. Recall that your functions have
been outlined in Chapter 2. The Supervisor will organise and direct data
collection in a Supervisory Area (SA) consisting of an average of 5 Enumeration
Areas (EAs). The Supervisor will coordinate and supervise all enumeration
activities in his/her assigned SA. Apart from being the census liaison o cer in
an SA, you are responsible for the technical, logistical and administrative issues
that Enumerators may encounter on the field, as well as their conduct.
The supervisor is a senior member of the field team, and is responsible for
quality data collection and complete coverage of the assignment area. S/he is
also responsible for the welfare and safety of Enumerators in his/her assigned
SA. The specific roles of a Supervisor include but not limited to the following.

6.2 General conduct

The general conduct of the Supervisor covers the following areas:
1. active participate in the interviewer and supervisor training and field
practical
2. making adequate preparation for field daily work , including provision of
adequate field materials and equipment;
3. transporting the team to the respective EAs;
4. managing the PDA including packing, unpacking, safekeeping, recharging
and uploading data, troubleshooting, etc.;
5. managing the safety, discipline, conduct and retraining of sta on the
field;
6. observing of interview quality and conducting re-interviews in sampled
buildings and households (details on re-interview is discussed in Chapter
13); and
7. maintaining regular contact with the Field Coordinator and DQM as well
as handling all meaningful requests and directives from them.

Page | 30
6.3 Fieldwork preparation
Before leaving for the field, the supervisor is responsible for collecting adequate
supplies of the materials the team will need and other preparation including:
1. Su cient quantity of Field O cer Manual;
2. Ensuring that Enumerators have access to internet to fetch their EA
maps;
3. Possession of letters of introduction to localities;
4. Fieldwork diary/notebook for fieldwork monitoring;
5. Provide PDAs and accessories (one per enumeration team); and
6. PDA recharging cases or external battery chargers.

6.4 Contacting Institutions and local authority

The 2023 PHC seeks to ensure that all persons and buildings in the country are
enumerated. However, it could be realised that access to some institutions such
as military barracks, police barracks, correctional facilities, health facilities,
boarding houses etc. are restricted, while it is imperative to have their
occupants and inmates enumerated during the census. Enumerators and
Supervisors should acknowledge that gaining access to enumerate the
occupants and inmates of these institutions will require special approval from
their managing authorities. The state will make available through the
Comptrollers, generic letters of notification and requests for access to such
institutions which are to be sent in advance by the Comptrollers. This is because
some of the institutions will need su cient time to process the request at their
headquarters. Supervisors should identify such institutions within their SAs early
enough, preferably immediately at the end of their training ,when assignments
are shared and liaise with the Field Coordinator and LGA Comptroller to collect
copies of letters earlier dispatched to request for permission to gain access into
the facilities to enumerate the buildings and persons residing in them. It is
worthy to note that some of these institutions have special protocol procedures,
as such you are expected to be conversant with them and strictly observe them
while processing the request.
Also, it is expected that the local o ce of the National Population Commission
had made initial contacts with the local authorities, traditional rulers and
community leaders prior to your deployment to the SA to facilitate community
entry. It is the Supervisor's responsibility to contact the LGA, district, community
and village o cials before starting work in an area. Letters of introduction will
be provided, but you are expected to introduce yourself and members of your

Page | 31
team and explain your mission to the local leaders. This will help to win the
cooperation needed to carry out the interviews and to ensure the safety of
respondents and field functionaries

6.5 Fieldwork implementation

The Supervisor will perform the following duties during fieldwork
implementation/data collection:
1. ensure that boundaries of EAs are clearly identified by the Enumerators;
2. check the completeness of building numbering and household listing
including pasting of census stickers/writing of numbers on buildings in
the SA;
3. study the contents of the enumerator manual on a regular basis to be
able to assist technical issues in a timely and e ective manner;
4. pay regular visits to each EA in his/her SA;
5. ensure that all household interviews are conducted accordance with the
protocol;
6. checking to ensure that each enumerator has a functional PDA;
7. observe interviews by each Enumerator;
8. conduct re-interviews in sampled buildings and households;
9. addresses boundary issues and non-response/refusals;
10. check that all households are visited and interviewed by Enumerators;
11. oversee the e ort of each enumerator revisiting ALL households and
correcting for the errors identified by the DQM;
12. check to ensure that data collected by Enumerators are synchronised on
daily basis;
13. escalate any unresolved issues to the Field Coordinator/DQM;
14. where necessary and feasible, secure accommodation for Enumerators
and ensure that and
15. observe security precautions and keep watch.

6.6 Observing interview

A Supervisor will observe the conduct of live interviews with each Enumerator
and in every E and observe the following:
1. ensure that the enumerator introduces you to the household and explains
your responsibility to visit the household and collect data;
2. attend interviews for your enumerators on a regular basis especially your
weakest enumerators;

Page | 32
 3. note that the first day of data collection is a critical time for you to
attend interviews for your enumerators in order to assess their capacity
after training;
4. must not participate in the interview or suggest things to the enumerator
during the interview, unless clarifications are requested by the
enumerator;
5. must let the enumerator complete the interview with the household;
6. must not comment on the enumerator’s performance in the presence of
household members;
7. must pay attention to di cult questions or concepts that the
enumerators have di culty in presenting clearly or household members
have di culty in understanding;
8. must also make note of those modules that the enumerator administers
well;
9. where necessary, handle the interview without the respondent noting that
the enumerator has failed;
10. check the use of language versions and appropriateness of the wording
used during interview;
11. check for misinterpretation of questions by the enumerator or lack of
understanding by the respondent;
12. discuss the interview with the Enumerator upon completion in order to
draw lessons from the experience together, and to address weaknesses
and shortcomings in data collection; and
13. pay attention to the respondents to observe and assess how household
members respond to the questions and identify items that are not clearly
understood.

6.7 Management of PDAs

Although the safety and care of PDAs rests with the Enumeration team, the
Supervisor will:
1. ensure that all the PDAs are stored in a safe and locked box or container
at the end of the day;
2. charging of PDAs every night to ensure that they do not run out of
batteries during interviews; and
3. provide technical support on PDA malfunction and replacement of a
faulty/damaged one.

Page | 33
6.8 Safety of Enumerators and Supervisor
It is important for a Supervisor to observe the following security measures:
1. be responsible for the safety of Enumerators as far as possible;
2. .stress to your team the importance of considering safety issues in their
work, without frightening them unnecessarily;
3. arrange logistics when it is necessary for Enumerators and ensure that
they didn’t travel alone to conduct late evening interviews;
4. accompany Enumerators to conduct interviews after sunset;
5. organise your fieldwork in a manner that ensures that you are able to
respond to any uncertain circumstances;
6. check with your Enumerators after every three hours;
7. pull out any Enumeration team that is facing or under threat and make
arrangement for another day when revisit is possible;
8. encourage your fieldworkers to keep a lookout for each other and to
follow their instincts regarding how to respond to di erent situations;
9. establish good working relationship with security agencies;
10. encourage them to discuss any concerns that they have with you; and
11. use your judgement to call the police or other sources of help in case of
any danger.

6.9 Safety of respondents

It is equally imperative for a Supervisor to ensure the safety of the respondents
during data collection.
1. encourage Enumerators not to exert pressure on a respondent on when
to start or continue with an interview when they do not want to;
2. advise Enumerators to make use of the Call Back Card if the respondent
wants to arrange the interview to another time;
3. remind Enumerators of their oath of secrecy and not disclose information
that they have been told during an interview to others in the community,
or with their friends or family; and
4. remind Enumerators to stay clear of discussing politics, religion, etc. with
the respondents.

6.10 Managing refusals and interview resistance

Although census taking is backed up by law, it is important to note that some
households or individuals may refuse to cooperate with the Enumerators. It is
the duty of a Supervisor to address cases of refusals or interview resistance if it
is beyond the handling of Enumerators. It is possible to find an entire
Page | 34
community, household head or senior household member to refuse to give
permission for a household member to participate in the Census, or just a
member to refuse to grant an interview. Upon receipt of a report from the
Enumerators, a Supervisor should make every e ort to reach out to them to
secure their permission. This may include stressing the importance of their
involvement, giving the fact that it is a national activity. If persuasion e orts
failed, you should escalate the situation to the Field Coordinator for necessary
action.
You should closely monitor the number of refusals from heads of households or
individuals reported by each Enumeration team. If an interviewer reports
frequent refusals or an unusually large number, it may indicate that he gives up
too easily or explains the Census inadequately. If this happens, the Supervisor
should promptly visit the EA and observe interviews. Interview resistance or
refusals can be handled in the following ways:
1. Approach the respondent from his point of view. Refusals may stem from
misconceptions about the survey or other concerns.. If there is a linguistic
or ethnic barrier between the respondent and the interviewer, the
supervisor should, if possible, send a di erent interviewer to complete
the questionnaire;
2. Postpone interview to another day; and
3. Carry out the interview yourself. The supervisor’s knowledge, skill and
maturity may enable him to complete a di cult interview when the
assigned interviewer has been unable to do so.

6.11 Dealing with pending interviews

Interview remains pending when information has not been collected from a
selected household or from a selected respondent and the return visits have
not been completed. Such a scenario remains with the Enumeration team until it
is completed. It is the responsibility of the Supervisor to keep track of, and
document pending interviews and ensure that they are completed.

6.12 Encouraging teamwork

It is the duty of a Supervisor to inculcate teamwork spirit among his team
members. Data collection is completed in an SA when all interviews are
satisfactorily completed and accounted for in all the EAs. Teamwork spirit can
be encouraged by:
1. Making the Enumerators to understand clearly what is expected of them
2. properly guiding and supervising the work of the Enumerators;
Page | 35
 3. recognising good work and e orts;
4. try to gain voluntary compliance before issuing direct orders;
5. involving Enumerators in decision making;
6. point out an error with tact, in a friendly manner and in private;
7. listening to the Enumerators's explanation with patience, examine the
cause of the problem and o er support;
8. don’t show preference for one or another of the Enumerators;
9. set examples of punctuality, good conduct, dedication and hard work for
Enumerators to emulate; and
10. be prepared all the time to address any challenges.

6.13 Quality control

As a supervisor, you are responsible for monitoring the performance of the
Enumerators as the data collection progresses. Errors may be committed by
the Enumerators at the beginning of data collection due to lack of experience
or lack of familiarity with the questionnaire or lack of attention to details. These
can be corrected with supplementary training. In the same vein, Enumerators
may become lazy or tired towards the end of data collection. A Supervisor
therefore, should intensify paying visits to EAs even at advanced stages of data
collection.
It is important to meet with your Enumerators on a daily basis to discuss the
quality of their work and digest any feedback that may be received from the
DQM. Common and specific mistakes can be corrected during such meetings.
The following can enhance the usefulness of the review meeting:
1. be careful while discussing examples of mistakes not to embarrass any
Enumerator;
2. read out relevant sections from the Field O cer Manual with the team to
resolve problems;
3. encourage the interviewers to talk about any situations they encountered
in the field that were not covered in training;
4. discuss with the team whether or not the situation was handled properly
and how similar situations should be handled in the future;
5. encourage team members to learn from one another, and should feel
free to discuss their own mistakes without fear of embarrassment; and
6. discuss both negative and positive issues arising from the quality control
observations.

Page | 36
6.14 Management of field resources
It is the responsibility of a Supervisor to ensure the availability of all necessary
field materials and equipment(listed in Chapter 2) in the SA. Items that will be
used in the field are to be provided to the Enumerators in a timely manner. A
checklist of items to be distributed will be provided by the LGA Coordinator. Any
shortfall in supply of materials or technical defects on any equipment should be
reported to the Field Coordinator. Records of the distribution of materials
should be taken well maintained for accountability purposes. In addition, the
Supervisor will ensure that the materials are judiciously put to use, and for the
purposes they are meant. Measures should be taken to ensure that field
materials are kept in a conducive and secure location at the end of the day.
Retrieval of items at the end of enumeration should be well documented and
organised. You should ensure that Enumerators signed the distribution sheet
while collecting materials and returning them to you. You are to ensure that all
items retrieved by you are safely stored and transferred to the next retrieval
point.

6.15 Conflict resolution

Conflict is a normal part of any healthy relationship typical in an assembly of
people like that of census functionaries that come from diverse backgrounds
and disciplines. It should be borne in mind that opinions and interests among
the functionaries will also di er. It is therefore imperative for a Supervisor to
also acknowledge that two people can’t be expected to agree on everything, all
the time. The key is not to fear or try to avoid conflict but to learn how to
resolve it in a healthy way. Conflict arises from di erences, both large and
small. It occurs whenever people disagree over their values, motivations,
perceptions, ideas, or desires. Sometimes these di erences appear trivial, but
when a conflict triggers strong feelings, a deep personal need is often at the
core of the problem. These needs can range from the need to feel safe and
secure or respected and valued. It’s important to keep in mind that the problem
may not be solved right away, even if the solution is obvious.
You should anticipate conflict to arise between you and any or all of your
Enumerators. Conflict can also arise within the Enumerators themselves. You
should be prepared to manage any eventuality that may occur. When conflict is
mismanaged, it can cause great harm to a relationship, but when handled in a
respectful, positive way, conflict provides an opportunity to strengthen the
bond between two people. The following tips can help you to resolve

Page | 37
di erences among your team members in a healthy way and forge stronger
work relationships:
identify the source of the problem, the stakeholders and the issue at hand;
take the time to listen to every participant and value each argument without
prejudice;
take reasonable time to weigh all options even if a solution or answer is readily
available as rushing to a resolution can make people feel like they’re left out in
the decision-making process;
1. go beyond the conflict and identify other challenges/barriers;
2. consider all options and create a long-term solution;
3. a common goal, stress its importance and how it can be achieved;
4. encourage aggrieved parties to make compromises establish and
collaboration to achieve the desired result;
5. build an agreement based on mutual respect;
6. apportion blame/censure on the culprit tactfully if necessary; and
7. escalate the issue to the higher census o cers for advise if the conflict
cannot be resolved within your team.

6.16 Enumeration of Enumerators and Supervisor

Recall that the procedure for enumerating census functionaries including
Enumerators and Supervisors has been discussed in Chapter 11. You are to
check with your enumerators to ensure that they are enumerated in their EA of
assignment, while the Supervisor will attach him/herself for enumeration to any
EA within the SA of assignment.

6.17 Clearance and Field Closure

6.17.1 Post Field Work

Post Field work refers to a period where field o cers are expected to complete
the assignment of data collection and returns from the field. This allows them to
be cleared for having done satisfactory work, and also retrieve the necessary
logistics that are meant to be retrieved. This shall consist of two broad activities
as follows:
1. Retrieval of Logistics
2. Clearing of field o cers and payment

Page | 38
6.17.2 Retrieval of Documents
These include the Personal Digital Assistant (PDA) and other instruments that
will be retrieved. The PDA and its accessories must not be misused as every
single material given to field o cers for field work will be collected and
transported at three levels; first from field o cers at LGA level; from LGAs to
States; and from States to HQ. This activity is done with support of a template
developed by the logistics team to ensure that all items are retrieved according
to a checklist on the template to facilitate the exercise. This activity should be
led by the DQM at the LGA level and State Coordinator at the State level.
At the end of enumeration, use the transmittal forms to return the following
materials to your supervisor:
● Personal Digital Assistant (PDA)
● Charger
● Power Bank
● Unused stickers

6.17.3 Field clearance

Clearing of field o cers and Payment is a crucial part of retrieval finalising of
fieldwork. Data collected from the field must be examined by the LGA Data
Quality monitor with support from the other DQM members to ensure data
completeness and quality before a team shall be cleared as having completed
their mission. However, the clearance will be validated from HQ. It is also to
facilitate payments of functionaries’ allowance as stipulated in their contract.
Clearance will strictly be done in teams and not individual field o cers. In other
words, a member of a team cannot and will not be cleared while the other team
members are working in the field or may have issues with their data.

6.18 Managing group listing and enumeration

The proposed methodology for the 2023 PHC House numbering and household
listing is the use of supervisory (SA) group listing method where all enumerators
in an SA work together to complete EAs a supervisory area consecutively. This
methodology has been successfully tested during the trial post enumeration
survey (PES).
During the Building numbering:
1. The team moves in a group starting with an EA then after completing
that EA, move to the next one until all EAs are completed within the SA

Equal access to male and female enumerators into dwellings and households
are not guaranteed in some cultural settings. In order to break any barrier that
will hinder smooth coverage of all buildings and households, exercise, A “group”
approach will be employed to number buildings and list households. It is
expected Enumerators of both sexes will be represented in an SA. The entire

Page | 40
functionaries in an SA (10 Enumerators plus 1 Supervisor) will work in an EA at a
time during building numbering and household listing. The Supervisor will
confirm the preloaded building numbers on the PDA, and write them on the
entrances/walls of buildings in the EA. S/he will then assign approximately
equal number of buildings to the each Enumerator to cover. For example, if the
total number of buildings in an EA is 100, the Supervisor will assign 10 buildings
to each Enumerator to cover. The team after completing the exercise in one EA,
will move to the next EA until all the EAs in the SA are completed.

15.19 Close of enumeration

It is the responsibility of the Supervisor to tidy up all fieldwork activities in a
systematic manner at the end of data collection. The Supervisor will liaise with
the Field Coordinator and the DQM to ensure that all households are covered
and that all outstanding data quality issues are resolved. The Supervisor will
assist in the retrieval of PDAs, accessories and other necessary materials. The
Supervisor will also liaise with the Field Coordinator and the DQM to issue
clearance of job completion to the Enumerators.

GENERAL INTERVIEWING TECHNIQUES

7.1 Introduction
The Enumerator is the most important/critical person in census enumeration.
Therefore, training should focus on ways and means of adequately preparing
the enumerators (and supervisors) for the ultimate task of collecting complete
and accurate data.
Enumerators’ manual is the e ective training and reference tool (contains
instructions on questionnaire handling & administration, respondent handling,
duties and responsibilities, enumeration procedures).
The ultimate goal of training is to have all enumerators (and supervisors)
MASTER the contents of Enumerators’ manual!
Bottom line: To ensure that Enumerators (and Supervisors) understand the
NATURE and PURPOSE of the Census, and to prepare them adequately to
enumerate persons in their assigned areas COMPLETELY and ACCURATELY!
Therefore, quality training is critical to collection of quality data.
Overall, TRAINING must be e ective, focused, and standardised in oder for the
enumerator to have confidence to conduct an interview.

7.2 What is an Interview?

The term interview means asking questions and obtaining responses from
members of a household. Interviewing is a challenging task, which requires
professional skill and patience. You can improve your interview skills during
training. Enumerators should ask questions as they are stated on the Census
Questionnaire and be alert to probe doubtful responses. Consult your
supervisor when you are forced by circumstances to record doubtful responses.
Enumerators will be sent back to the field to verify doubtful entries or to correct
mistakes that are detected in their work. Remember, the success of the entire
census operation depends on how well you conduct interviews with the
respondents. Your responsibility as an enumerator therefore, demands that you
administer interviews in accordance with the laid down procedures and record
the responses correctly on the PDA.

7.3 INTERVIEW TECHNIQUES

Tips to enumerators: How to handle interviews!
1. Stress CONFIDENTIALITY of information collected
Page | 42
2. Understand the exact purpose of the census and each question…to know
if the responses are adequate.
3. Read out the questions exactly as written. Small changes in wording can
alter the meaning of a question.
4. Ask the questions in the same order as they are given in the
questionnaire. Maintaining flow is important.
5. Ask all the questions, even if the respondent answers two questions at
once.
6. Help your respondents to feel comfortable, but make sure you do not
suggest answers to them.
7. Let people take their time to answer questions. Do not hurry the
interview.
8. Do not ask leading questions.
9. Work steadily and make sure that the answers are clear before writing
them down.
10. If unclear tactfully ask further questions to obtain the correct answers i.e.
PROBE.
11. Remain neutral throughout the interview.
12. Do not show surprise, approval or disapproval of the respondent’s
answer by your tone of voice or facial expression
13. Record answers immediately once clear. Never rely on writing answers in
a notebook to transfer to the questionnaire later.
14. CHECK the whole questionnaire before you leave the household to be
sure it is completed correctly.
15. In case of refusal remain courteous. Stress the importance of the exercise
and confidentiality of information collected.
16. Build rapport with the respondent, ask questions slowly to ensure the
respondent understands the question.
17. When leaving a household, always remember to thank the members for
their cooperation.
18. Act as though you expect friendly cooperation and behave so as to
deserve it. Before starting exchange proper greetings, identify yourself,
explain the purpose of your visit, answer any questions about the census
that the people may have, BUT... do not spend too much time asking
and/or answering unnecessary questions

Page | 43
7.4 Interview Resistance
Interview resistance is a situation where the respondent is unwilling to
co-operate with an enumerator. Several reasons may be responsible for the
respondent to be unwilling to cooperate such as:
a. Non-cooperation by the head of household for personal reasons.
Common responses in such instances are: “Oh, I am too busy right now”,
or “Come back some other time”. You have to decide whether the
respondent is really busy or is demonstrating interview resistance. A
puzzled or suspicious look in the face of the respondent gives a clue for
the reason for the interview resistance.
In such a situation, you should use tactical emotional intelligence that you
have learnt in the Chapter on Interpersonal Communication Skills and
try to gain the confidence of the respondent. Where s/he is still resisting,
you should refer to your Field Supervisor immediately.
b. Wrong introduction: Where you open the interview by saying, “I am
looking for the head of the household” or “Are you the head of this
household?” Responses such as “What for?” or “Who are you” or “I don’t
know” made after some hesitation may indicate interview resistance. In
this situation, you should first apologise for your introduction and
reintroduce yourself.
If faced with interview resistance, you must create an atmosphere of
friendliness between the household member and yourself. In general, you are
the one to break the barriers and move forward and carry the public along with
you.
7.5 Ending the Interview
How the enumerator ends the interview is as important as the way s/he begins
or conducts it. There are many ways of saying good-bye and thank you
gracefully. S/he should be sure to say one to every respondent and household.
His/her language should express this gratitude for the cooperation received
from them. Sometimes the enumerator may be o ered food or drinks out of
courtesy and not to influence him/her. Saying no to gestures may cause
problems. Saying yes may prolong the interview. What to do? Enumerators
should weigh the situation carefully and decide on the spot. If they must say no,
be nice and polite. The enumerator’s body language and attitude will win
him/her the commendations of the public in the enumeration area(s) assigned
to you.

Page | 44
7.5 Close of Enumeration
After enumeration is completed in the EA, enumerators are to ensure that all
data collected are synchronised and all corrections e ected. The Field
Supervisor will check that tasks have been completed correctly and completely
thorough his monitoring application. Once the Field Supervisor is satisfied with
the enumerators’ task, he will require them to submit their returnable items and
instruct them on what to do next.

 CHAPTER EIGHT
KEY CONCEPTS AND DEFINITIONS
The aim of this chapter is to make you understand the definition of basic
census concepts and terminologies. At the end of the chapter, you should be
familiar with the important census terms and concepts. The census concepts
listed here are not exhaustive but serve as an aid to assist you in conducting
thoroughly, correctly, confidently and in tandem with other co-enumerators all
over the Federation.

8.1 Population Census

A population census is the total process of collecting, compiling, evaluating,
analysing and publishing or otherwise disseminating demographic, economic
and social data at the smallest geographical level appropriate pertaining, at a
specified time, to all persons in a country or in a well-delimited part of a
country.

8.2 Housing Census

A housing census is the total process of collecting, compiling, evaluating,
analysing and publishing or otherwise disseminating statistical data relating to
the number and condition of housing units and facilities as available to the
households pertaining, at a specified time, to all living quarters and occupants
thereof in a country or in a well delimited part of a country.
By definition therefore, a Population and Housing census requires that each
individual person and each building is enumerated separately and only
once.Census operation is confined to a well-defined territory and reference
period.Collecting information on the characteristics of living quarters and the
composition of the occupants of those quarters form part of the housing
census components of census exercise.

8.3 Census Night and Census Reference Period

A census night is the night immediately before the first day of enumeration. It is
the night when homeless persons are usually enumerated
The census reference period is the time from the zero hour (00:00) of the first
enumeration day to the midnight (24:00 hrs) of the last enumeration day. The
time of visit by an enumerator for an interview must therefore be within the
zero hour of the first day (29th March, 2023) to the midnight of the last day2nd
April, 2023) assigned for the census enumeration. This means that:

Page | 46
All persons must be enumerated within the census reference period. Note,
between the census night and the time of enumeration, the composition of a
particular household might have changed.
Children born up to the time the enumerator comes to the household (see 2.7
for definition) are to be enumerated, but children born after the enumerator
has completed the household, even if the birth occurred within the census
enumeration period, should not be enumerated. Similarly, persons who died
within census enumeration period, but before the enumerator come to the
household are not to be included, and any death that occurred after the
enumerator has completed the household is not to be erased even if it occurred
within the census enumeration period but after the visit of the enumerator”.
Note: No enumeration should take place before or after census period unless
authorised by the Chairman (NPC).
Only persons physically present at the time of enumeration shall be eligible to
be enumerated.

8.4 De-Facto Census

A de-facto census is an enumeration in which people seen are enumerated
according to where they stayed/slept on the night preceding the day of the
enumerator's visit. The 2023 Census is a de facto census. In other words, people
not physically present are not enumerated and those seen are enumerated in
their respective place of abode.

8.5 Locality
A locality is defined as a distinct population cluster also designated as inhabited
place or settlement in which the inhabitants live in, has a name or a locally
recognized status.
It thus includes fishing camps, hamlets, mining camps, ranches, farms, markets,
towns, villages, cities and many other population clusters that meet the criteria
specified above.
Note: Wards, quarters or housing estates within a town or city should not be
regarded as a locality. More Localities does not translate to higher population
fora Local Government Area.
It is a geographical phenomenon that localities or settlements urbanise over
time and merge with one another. For instance, a settlement with a name and a
traditional ruler may exist at a fairly short distance from another bigger
settlement some time ago, with the passage of time, the bigger settlement may
Page | 47
expand and finally subsume the nearby settlement and the smaller one is now
merged with or enclosed within the bigger settlements. Both the big and the
smaller settlements should retain their distinct identities (e.g. name etc.) as
localities.
In another instance, some new towns are either created by the government or
may have started spontaneously and have developed into settlements over
time, this should also be regarded as localities. However, it should be noted that
in big cities and towns where expansion has taken place naturally over a period
of time, no subsection or wards within such cities should be regarded as
alocality.

Figure 3.1: Satellite Imagery of a Locality

The following types of localities are identified for the purpose of census
enumeration:
a. Sub-primary locality: A sub-primary locality is a settlement which does
not independently exist on its own in terms of ruler-ship, social, political
and economic activities. There is always a substantial distance separating
it from the parent settlement.
b. Primary locality: This is a locality that has been in existence, known by
one distinct name and the inhabitants consider themselves as a unit. For
example, Orile Agege in Agege, Fegge in Onitsha, Kurna-Kwaciri in Fagge,
Wuse in Abuja etc.
Page | 48
 c. Secondary locality: A secondary locality is a settlement with two or more
contiguous primary localities within an LGA. for Example, Agege
comprises Orile Agege, Tabon-tabon etc; Onitsha comprises Fegge,
Odoakpu, Woliwo etc; Fagge expanded to cover Sabon Gari, Rijiyar
Lemo, etc.
d. Tertiary locality: A tertiary locality is a settlement comprising two or
more secondary or primary localities that has expanded across two or
more LGAs.
Each of the categories have been clearly identified and geocoded during the
Enumeration Area Demarcation.

8.6 Building

A building is any free-standing structure comprising one or more rooms,

covered by a roof or not and may or may not be enclosed within external or
dividing walls. A building may be used for one or multiple purposes.
It may be used for residential, commercial, or industrial purposes and can
therefore be a factory, shop, dwelling apartment, garage etc.

Figure 3.2: Typical Buildings used for both Residential and Commercial Purposes.

Figure 3.3: A row of 4 buildings.
Note: Sometimes Terrace/Chain Buildings are found along a street. This is a row
of buildings/houses that are joined to each other. “row of terraced houses (with
at least 3 attached or connected dwellings each with separate access to the
outside) should be identified separately” (UN Principles and Recommendations
on Population and Housing Censuses).

8.6.1 Types of Building/Structure

There are di erent types of buildings for the purpose of census. These are:
1. Single building/bungalow (Detached): A building without an upper
floor and is not attached in any way to another building.

Figure 3.4: Single building/bungalow (detached).

2. One-storey (Detached): A building with one upper floor and is not
attached in any way to another building.

Page | 50
 Figure 3.5: One-storey (detached).
3. Two-storey (Detached): A building with two upper floors and is not
attached in any way to another building.

Figure 3.6: Two-storey (detached)

4. Multiple-storey (Detached): A building with three or more upper floors
and is not attached in any way to another building.

Page | 51
 Figure 3.7: Multiple-storey (detached)

5. Single building/bungalow (Semi-detached): A single-family home that

shares a single wall with the next building.

Figure 3.8: Single building/bungalow (Semi-Detached)

6. One-storey (Semi-Detached): A building with one upper floor that
shares a single wall with the next building.

10. Metal Container/Shed: A Container is usually a steel cabin used to ship
goods but now converted for various uses. (E.g., Shops/Stores; O ce
or Residence).

Figure 3.13: Metal Container/Shed.

11. Porta Cabin: A building that can be moved by truck and that can be
used as a residential unit for a short period of time especially by
tourists.

Figure 3.14:A Porta Cabin

Page | 54
 12. Kiosk: a small open-fronted hut or cubicle from which newspapers,
refreshments, tickets, recharge cards etc. are sold.

Figure 3.15: A Kiosk

13. Traditional Mud Structure: These are buildings built with mud and
thatched palm fronds for roofs.

8.6.2 Building Use

Buildings have various uses which can be residential only, mixed use,
institutional or non-residential. These four broad categories have been divided
into twenty-four24 possible uses.:
1. Residential (Housing/Dwelling unit(s) only
2. Residential with Commercial Activities
3. Residential with Social Services ( e.g. Part for Sleeping and part as school
or Hospital)
4. Residential with Religious Activities
5. Institutional Accommodation (Hostel, Hotel, Prisons etc.)
6. Institutional Temporary Camps (IDP, Military etc.)
7. Agricultural Services
8. Commercial Services
9. Educational Services
10. Government O ce Services
11. Hospitality Services Non-residential
Page | 55
 12. Industrial Services
13. Military Services
14. Religious Services
15. Parking and Storage Services
16. Transport Services
17. Food bam/Silo
18. Standalone Utility Services(Toilet/ Bathroom etc.)
19. Domestic Equipment/Machine house (Generator, Grinding machine)
20. Uncompleted and Unoccupied
21. Dilapidated and Unoccupied
22. Completed and Unoccupied
23. Other (specify)
24. Floating Building

8.7 Compound
A compound is a building or group of buildings usually enclosed or not by a wall
and having one or more structural units with a common entrance. In some parts
of Nigeria, housing units or structures are traditionally located within a
compound. Examples of compounds are illustrated below:
● If a building and a boy’s quarter are enclosed within an external wall or
fence, each structure should be assigned a number.
● If a group of huts fenced/not fenced round with a common entrance are
in a compound, the structures should be numbered separately and the
use of each building clearly stated.
Clustered buildings within a fenced or an unfenced compound but with di erent
ownerships (e.g., a fenced or unfenced Estate) should be treated as individual
buildings.

Page | 56
 Figure 3.4: Typical modern andTraditional Compound

8.8 Household
A Household consists of a person or group of persons living together usually
under the same roof or in the same building or compound, who share the same
source of food and recognize themselves as a social unit with a head of
household. They may or may not be related by blood.
The criteria for categorising a household are:
1. Living under same roof/compound
2. Seeing themselves as a unit
3. Sharing of same catering arrangement
4. Recognizing one adult member as head
5. May or may not be related by blood

8.8.1 Types of Household

Types of household are listed below:

S/N TYPE OF HOUSEHOLD

1 Regular household
2 Institutional (Long stay)
3 Institutional (short stay)
4 Floating/Transient persons
5 Diplomatic corps
6 Census Functionaries

Page | 57
8.8.2 Regular Household
A Regular household usually recognizes one of its members as the head; shares
a common catering arrangement and members conduct themselves as a social
unit. This can be one person or multi-persons households. A one-person
household consists of a single individual, man or woman and a multi-person
household consists of two or more members.
An example of a regular household can be a man and his wife, with or without
children, relations and house-helps. All members of a household are not
necessarily related by blood or marriage because sometimes house helps and
visitors can be a part of the household. Similarly, not all those related by blood
and living in the same building or house or compound are necessarily members
of the same household if they do not recognize one of them as the head or do
not eat from a common pot.
A man may have more than one wife, with some of the wives living in di erent
buildings (or outside) the same compound. Where they live in the same
compound and prepare their food/meals separately, but recognize the man as
the head of household, they are treated as one household. In a situation where
one or some of the wives do not live with the man in the same
building/compound, both should be treated as di erent households.
Two or more people (related or not related to each other) sharing a room or
apartment are regarded as a household if they share catering arrangement
and one of them is recognized as a head of household. If they feed separately
or each of them recognizes himself as independent head of household, then
each of them is a separate household in spite of the fact that they sleep and
live inside the same room.
Married children with their spouses and children, living in the same house with
their parents, but having separate catering arrangements are separate
households. Also, two brothers who live in the same house with their wives and
children may form separate households, depending on their catering
arrangements and agreement on one head. (In other words, they are separate
households if they do not share common catering and they do not recognize
one of them as the head). A household is not necessarily the same as a family.
A family compound may, for example, contain family members of di erent
households; a father’s household may be next to that of uncles or brothers or
even the children. Depending on the composition, a household can be greater
or lesser than what constitutes a family.

Page | 58
8.8.3 Institutional Household (long and Short)
An institutional household is a collective household in which members do not
have any recognized head of household. The members may live together in the
same building or compound and share a common catering arrangement.
Students in the hostels do share a common residential and catering
arrangement, but neither the housemaster nor the principal of the college, is
the head of household. Similarly, inmates take their food from the same pot
and live together in the same yard but neither the Warden nor another
correctional facility o cial is their head of household. Therefore, an institutional
household is a type of living arrangement for people with a common
characteristic, who live under a common rule in an institutional building.These
can be further categorised as institutional long or short stay.
1. Institutional (Long stay):

These are households where members receive services provided by an

institution and are likely to be found even after a long period of time. Examples
are:
● Basic Schools (Kindergarten, Primary, JSS)-boarding
● Senior High School (SSS, Secondary)-boarding
● Tertiary Institution (University, Colleges, Polytechnics, Nursing School etc.
)-hostels
● Service Training Institutions (Police Trg., Etc.)
● Religious Training Institutions (Seminary, Theological School, Monastery,
Convent, Qur’anic school etc.), Hostels
● Hostel (Private/O Campus)
● Orphanage
● Old People Home/Nursing home
● Mining Camp/ Road Camp/ Farm Camp
● Refugee Settlement/Camp
● Correctional Homes/Borstal/Leper Settlements (Leprosarium)
● Internally Displaced Persons Camps
2. Institutional (Short stay):

These are households where members receive services provided by an

institution for a short time. Examples of these institutions include:
● Hospitals, Polyclinics, Clinics, Health Centres
● Remand Homes, Police/ OtherCells
● Divine Healing home, Prayer Camp
Page | 59
 ● Herbal Healing Centres, Bone Setting Centres
● Hotel, Guest House, Lodge
4. Floating/Transient Population
Floating Households are groups of persons who reside temporarily in certain
locations other than their usual place of residence for a certain amount of time
and for various reasons.
Transient Populations are individuals who are on their way out or coming into
the country at the time of enumeration and are not likely to be enumerated
with their normal/regular households. They include transit passengers at
seaports, airports, international motor parks and markets.
Floating and Transient households are found in places such as: Transit Post e.g.
At Railway Station, Lorry Park, Market (Inside or Outside), Other Location of
Floating Population,
5. Diplomatic Corps
Diplomatic Corps are households or citizens of foreign countries that are
employees of Embassies, High Commissions and Consulates living in the o ces
or in their private residences. E.g. United Nations O cials etc.
6. Census Functionary
Census Functionaries are individuals who are involved in conducting census
activities. These are Enumerators, Supervisors, Field Coordinators, Data Quality
Assistants,Data Quality Managers, Geo- monitors, independent monitors, Local
Government Area census coordinator, State census coordinator,Call centre
agents, Census Operations Tracking Team (COTT))etc.

8.9 Place of Usual Residence

This is the place where the respondent lives or intends to live for at least six
months in a calendar year, engages in economic and social activities and has
his living quarters. It is the place where the respondent sleeps, keeps his
personal belongings and from where s/he goes to work or school or interacts
socially. Consequently, the place of usual residence is the geographical area
where the respondent lives. It may neither be the place of birth nor the place of
origin. For example, for a person born in Sokoto who now lives in Enugu, Enugu
is the place of usual residence. Similarly, for a person whose place of birth and
place of origin is Lagos but lives in Abuja, the place of usual residence is Abuja,
if s/he meets the above criteria.

Page | 60
8.10 Housing Unit
A Housing unit is defined as a separate and independent place of abode that is
intended for habitation by one or more households.
8.10.1 Occupied Housing Units

Occupied housing units are residential buildings occupied by regular households

during census enumeration. It could be a building or some form of shelter
arranged for human habitation and occupied by the households. Some
structures may serve more than one purpose. In some cases, people live in the
building and some of the rooms serve as o ces or shops where people
transact their business or sell their goods during the day
8.10.2 Secondary Units for same Household

Secondary housing units are additional dwellings that are occupied by the same
household within the same compound with the structure occupied by the
household. Examples are Boys’ Quarters and other dwellings. However, if
structures such as the main house and Boys’ Quarters on the same compound
are occupied by di erent households they are not considered as secondary
housing units.

8.11 Homeless Households

These are identical to regular households except that they do live in a
conventional housing/dwelling unitat the time of enumeration. A homeless
household can be made up of one or more members.

8.11.1 Homeless Persons

Homeless persons are individuals who sleep in public places such as footpaths,
pavements of markets, shopping centres and motor parks. Note: Mentally ill
persons, who live in homes with their relatives, belong to regular households.

8.12 Nomadic Household

Nomadic household consists of persons who migrate from place to place in
search of pasture for their animals, such as some Fulani. They do not settle in
one place for a long period. Some stay in a place for only a few days. They are
usually found living in groups, with identifiable households, staying in semi-
permanent structures.

Page | 61
8.13 Fishing and Hunting household
Fishing and housing household consists of people on fishing or hunting
expeditions who are not returning to their regular homes at the time of
enumeration. They may spend days on water or in the bush and may bring their
crafts/boats to anchor at a particular point, which is outside their regular
homes, for sale or preservation of their catch.

8.14 Internally Displaced Persons (IDPs)

Internally Displaced Persons (IDPs) are people who have been forcefully
displaced from their usual place of residence before the census due to
insurgency etc. Majority of them are part of regular households and are
displaced due to insecurity or conflict. There are four categories of IDPs; those
living as regular households in the camp, Individual persons in camp, those
living in organised settled units and those integrated in normal households.

8.15 Head of Household

The head of household is a member of a household whom the other members
of the household recognize as such. S/he is usually an adult who makes
decisions on behalf of its members. This can be a male or female.

8.16 Enumeration
Enumeration is the process of interviewing all members of a given population
and collecting socio-demographics and other information about each person

3.17 Enumeration Area

An Enumeration Area (EA) is an area carved out of a bigger locality or a group
of localities with well-defined and identifiable boundaries. It is an area a team
of enumerators is expected to cover during the census. The essence of carving
out these units is to avoid any omission or duplication of count of people and
households during enumeration.
An EA that is made up of more than one locality is referred to as multi-locality
EA. Locality that consists of more than one EA is known as a multi-EA locality
while a locality having just a single EA is regarded as a single EA locality.

3.18 Special Enumeration Area

These are EAs that are higher (i.e. above 650 persons) or lower (below 250
persons) than normal EA threshold.

Page | 62
3.19 Questionnaire
A questionnaire is an instrument used to capture detailed information in a
census or survey. For the 2023 Population and Housing Census the
questionnaire instrument is programmed in a PDA/ tablet (CAPI) and will be
used to collect information on buildings, households and persons.

3.20 Building Numbering

Building numbering is the assignment of numbers to all buildings in an
Enumeration Area in a systematic and or sequential manner for the purpose of
actual enumeration.

3.21 Household listing

Household listing is the process of identifying and counting households in a
building in each of the Enumeration Areas.

3.22 Post Enumeration Survey (PES)

PES is a complete re-enumeration of a representative sample of a census
population to measure content and coverage errors in the census exercise.
For the purpose of the 2023 Population and Housing Census,the PES will be
conducted a few weeks after the main census enumeration in selected EAs. In
addition to selected questions used in the main census, there are certain
additional questions.

3.23 Di culty in Performing Activities

For the purpose of the census, di culty in performing activities means di culty
a person may have in undertaking basic functioning activities, including seeing,
hearing, walking or climbing stairs, remembering or concentrating, self-care,
communication (expressive and receptive), upper body activities, a ect
(depression and anxiety), pain, and fatigue. An individual may have no
functional di culties, some di culties and/or may have a lot of di culty.
Literacy means that one can both read and write with understanding in any
language; If one can read but cannot write then S/he is illiterate. A literate
person can read and write with understanding a short and simple statement
about his/her daily life in any language (local or foreign). A person who can
read and write only figures and /or own name is illiterate. A person who can
read and/or write only a ritual (ceremonious or religious) phrase, which has
been memorised, is also illiterate. A person has to be age six or more to be
treated as literate for thepurpose of census.

 CHAPTER NINE
USE OF MAPS

9.1 Importance of Maps in Population and Housing Census

Mapping has been an integral part of census taking for a long time. Over the
years, census maps have played a critical role in all processes from preparation
to dissemination of census results. With the recent development in technology,
NPC has adopted digital mapping techniques using the Geographical
information system (GIS) to improve the quality of census operation. The
importance of maps in the census process is to support enumeration and to
present aggregate census results in cartographic form. In general terms,
mapping serves several purposes in the census process, as follows:

9.1.1 Pre-Enumeration
:Maps ensure coverage and facilitate census operations (pre-enumeration).
Maps help to ensure that every household and person in the country is counted
and that no households or individuals are counted twice. For this purpose, the
country has been delineated into small data collection units called enumeration
areas.
9.1.2 Enumeration:
Maps support data collection and can help supervise census activities (during
enumeration). During the census, maps ensure that enumerators can easily
identify their assigned enumeration areas, in which they will enumerate
households. Maps are also issued to the census supervisors assigned to
enumerators to support planning and control tasks. Maps can thus also play a
role in supervising the progress of census operations. This allows supervisors to
strategically plan, make assignments, identify problem areas and implement
remedial action quickly.

9.1.3 Post Enumeration

Maps make it easier to present, analyse and disseminate census results (post
enumeration). The cartographic presentation of census results provides a
powerful means for visualising the results of a census. This supports the
identification of local patterns of important demographic and social indicators.
Maps are thus an integral part of policy analysis in the public and private
sectors.

9.2 Elements of Census Maps
Maps of di erent scales play critical roles in census taking, from pre-census
mapping to being a major guide during actual enumeration and a powerful tool
for census data presentation.
9.2.1 Map Definition:
A Map is a representation of either the entire earth surface or its part in
reduced form, showing Natural and Man-made features existing on it. A map
may be described as a carefully, systematically designed visual display for
recording, calculating, displaying, analysing and understanding the
interrelationship of a given spatial information. A map is drawn to scale. A
sketch on the other hand is a non-systematic graphic representation of
features. It is usually not drawn to scale. Sketches are useful when maps are not
available. A map may be in hard copy or Digital Format.
In hard copy format, the map is printed on a Paper at a specific scale but in
Digital format the map is compiled as a virtual image on the electronic medium
(Tablets, laptops, desktops etc.)and can be zoomed in or out to desired scale as
applicable. This is the main advantage of the Digital Map over the hard copy
map. The map to be used for this Census is therefore in Digital format on the
tablet (PDA). They are represented in Raster (Satellite Imagery) and Vector
Format (Line, Points and Polygons).
9.2.2 Satellite Imagery:
These are remotely acquired data of parts of the earth surface (ground
features by space borne satellites they are used to create photograph-like
representations.
The importance of the use of Satellite Imagery in Census are hereby
highlighted:
Map features from satellite imageries appears as on the ground, helping non
map experts to easily identified features on ground
The Satellite Imagery is used as a backdrop of the EA boundary and other
Census features for this Census.
Satellite Image Interpretation: Satellite Image interpretation involves visually
identifying features on the satellite image correctly as it is physically on the
ground. It is important for Enumerators and other Census functionaries to have
a basic knowledge of how to recognize features represented on the Satellite
imagery which is the backdrop to the Census map.
Page | 65
All Census Map users should understand basically that the Satellite image is an
overview of all features. They appear as you will see them imagining you are in
an aircraft. Therefore, the building view is mostly the top. So also, are tree
canopies, roads and other features as of the time of acquiring the data

9.3 Basic image interpretation principle

The basic image interpretation principles that can help map interpretation
include:
9.3.1 Colour or Tone
Old buildings with rusty corrugated roofs will have dull brownish colour while
newly constructed metal roofs will have brighter colours depending on the roof
type. New excavations will have a bright appearance etc. Tarred roads will have
Grey colour and Vegetation green. Swampy areas with overgrown Vegetation
will have a darker greenish colour etc.

9.3.2 Shape
Tarred roads appear with straight edges while footpaths and untarred roads
have rough edges. All features will have their overview shape on the Satellite
image. E.g., a house with a courtyard. A Swimming pool, a school building
arrangement and a Stadium. This can easily be recognized by their appearance
on the Satellite Imagery. Also, note that all Natural features such as Forest,
streams & Rivers, Hamlet’s boundaries will have irregular edges/shapes while
man made features such as Buildings, Roads, Cultivated Lands, Stadium,
Swimming pool, etc. have regular edges/shapes.

9.3.3 Association
An identified feature can help to interpret other naturally associated features.
E.g., the presence of a hub of vehicles points to a Motor or Car Park. Presence
of boats in the imagery gives an idea of a harbour. A road crossing a river
means there is a bridge. A wide playground with organised buildings depicts a
school etc.

Page | 66
 Fig 9.1 Tin Can Island Port ShowingAssociation

9.3.4 Size
Size of objects in an image is a function of scale. It is important to assess the
size of a target relative to other objects in a scene, as well as the absolute size,
to aid in the interpretation of that target. A quick approximation of target size
can direct interpretation to an appropriate result more quickly. For example, if
an interpreter had to distinguish an estate, and had identified an area with a
number of buildings in it, large buildings such as factories or warehouses would
suggest commercial property, whereas small buildings may indicate residential
use.

shape and size (Shape/Size)

Page | 67
9.4 Types of Census Maps
Local Government Area Maps: (LGA Maps): This is the administrative map for
each LGA. It is the seamless array of all the EAs for the entire LGA covering
every inch of land without overlap or gaps. It is to aid planning for Census to
allocate both human and material resources on LGA basis as well as monitoring
of Enumeration progress during head count. The Feature layers on this map
include:
a. Satellite Imagery: Back drop of all Physical features and Census Entities.
b. Enumeration Area boundary with displayed ID at specific zoom level
c. Supervisory Area boundary with Displayed ID at specific Zoom level
d. Registration Area/Ward with displayed ID at specific level
e. Important features such as Schools, Hospitals, Petrol Stations etc. to aid
location identification
f. Drainage (Rivers, Water bodies, Canals etc.)
g. Roads well annotated.
h. Buildings: All buildings identified during the Demarcation exercise.

9.4.1 Supervisory Area (SA) Maps

This is the Supervisors’ Administrative Map covering a specific area with a
number of EAs allocated to a supervisor. It will have the total number of EAs
within the SA clearly identified with their boundaries and IDs displayed on the
map.
The SA map is a ‘Zoom in’ from the LGA map. This will aid the Supervisor in
seeing the neighbouring SAs/EAs as well as aid each Enumerator within his/her
Supervisory area to identify his/her boundary of Enumeration. It will have all
the Feature Layers of EA, SA boundaries, Important features, Drainage, Roads,
footpaths and all Buildings within the EA. All the features are well annotated or
coded where applicable. All LGA and Ward boundaries are also shown where
applicable.

9.4.2 Enumeration Area (EA) Map

Nigeria has been divided into small geographic units called Enumeration Areas
(EAs) during mapping for purposes of enumerating all persons. Due to factors
such as population density, geographic terrain and distances to be travelled,
EAs have been demarcated to facilitate e ective canvassing by an enumerator.
Enumeration Area (EA) map shows the area of assignment for a team of
enumerators. Each team of enumerator will be assigned an EA with clearly
defined boundaries during the enumeration and will be responsible for visiting
Page | 68
every household and record the particulars of all persons who spent the
CENSUS NIGHT in the EA ensuring he/she does not miss out or double count
any household in the EA.
The supervisor will help to identify the EA boundaries. Make sure you familiarise
yourself with your EA before you start work. Study the EA map carefully so that
the boundaries are clear to you, both on the ground and, on the digital map. In
most cases, the boundaries of your EA follow easily identifiable features such as
buildings, churches, mosques, rivers, streams, roads, tracks and footpaths, etc

9.5 Map Orientation

Map orientation is the process of aligning a map with ground features or the
process of determining how directions on the map align to directions on the
ground. It is also used for canvassing the area for the conduct of Census
enumeration. It is important to know how to align all maps to the ground
correctly, to easily identify and locate features on the ground as they
correspond on the Satellite Imagery.
Note: The di erence between orientation and direction is that Orientation is the
position of an object in relation to its environment (everything), while direction
is movement or facing towards something specific (e.g. North). In other words,
only when map features align to ground features that direction of map features
can be e ectively identified.

9.5.1 Methods of Map Orientation

There are four basic methods of map orientation that can conveniently be used.
The methods are:
a. Orientation by Sun: The Sun rises in the east and sets in the west.
b. Orientation with the help of compass:A compass can be used to find the
North and then the intended direction of movement.
c. Orientation by ground features: Aligning map features to ground
features and
For the purpose of 2023 Population and Housing Census, map orientation will
be done using the “locate me” feature to determine precise position of objects
on ground.

Page | 69
Fig 9.3: Aligning the above imagery, if the Enumerator is standing on Bida Road
facing Nigeria Police force Headquarter Kaduna, the Enumerator must check
that the Wema Bank PLC Building is on his/her left across Bida road by the
sharp bend.While the Ranchas Bees Stadium is to the Enumerators right.

9.5.2 Navigation
The Digital Map for this Population and Housing Census is running on a
customised application called Censuspad which has the capability to help
Enumerators identify their area of assignment easily and accurately. This will be
treated in chapter 6

9.6 Map Updating

This is the process of adding information about new features such as new
buildings, roads, mast other prominent features, Floating populations points
found on the ground to the digital map , and correcting names, spellings of
features on the map. This process also allows you to mark structures and
features that are no longer in existence. The updated data will be added to the
database. (See Chapter 6 for a step-by-step guide on how to use the
CensusPad application in the PDA to update your EA Map).

9.7 Identifying Overlaps and Gaps in EA Map

Steps have been taken to ensure that there are no overlaps and/or gaps during
the EAD: An overlap occurs when one EA boundary crosses into another EA. If

Page | 70
some structures within the boundary of your assigned EA are numbered )
anytime during the period of listing, this gives an indication of a possible
overlap with another EA. A gap is a part of the land area (space) that does not
belong to any EA or simply unaccounted for as part of any EA. If some
structures around the boundary of your assigned EA are not numbered when
the listing period is ended, this gives an indication of a possible gap. To avoid
overlaps or gaps, all Enumerators must ensure that they know and collaborate
with all other Enumerators sharing EA boundary with them. In the same vein, all
Supervisors must ensure that they are familiar with all other Supervisors
working in SA that share S.A. boundary with them. Should you encounter any
overlap or gap, report to your supervisor, who will liaise with other supervisors
sharing the same supervisory area boundary with him/her, who should also
report to the Field Coordinator.

 CHAPTER TEN
TABLET FEATURES AND USE

10.1 Using the Tablet

10.1.1 What is a Tablet?

Tablets (i.e. PDAs) are ultra-portable computers which can run a variety of
software programs. For this PHC, a hybrid software application has been
developed purposely for house numbering, household listing and persons
enumeration. The type of tablets used for this enumeration exercise are
designed so that gentle pressure on the tablet screen will not have any e ect.
Therefore, it is necessary to apply moderately firm pressure on the screen in
order for the tablet to recognise the finger touch. However, do not apply
excessive pressure on the screen to avoid damages to the screen surface.
A personal digital assistant (PDA), also known as a handheld PC, is a variety of
mobile devices which functions as a personal information manager. PDAs have
been mostly displaced by the widespread adoption of highly capable
smartphones, in particular those based on iOS and Android.
10.1.2 Identifying the parts of the Tablet
To get started with your device, you first have to familiarise yourself with keys
and button your device.
● Locate the;
● Power Button
● Volume Button
● SIM Slot
● USB/Charger Port
● MicroSD Slot
● Back Button
● Home Button
● Camera
● Menu Button
● Light Sensor

Page | 72
10.1.3 Procedure for Powering Up (“Booting”) the Tablet
To power the Tablet the steps below must be followed:
● Press and hold to turn the device on or o .
● Press to turn on or lock the screen
● Follow the steps below to boot up the Tablet and log in to your Samsung
Tab.
● Press on the Power button at the top right-hand side of the screen, to
power up the Tablet.
● Click on the field titled “Password” and use the keyboard to enter your
password. This password will be given to you by the Technical Support.
● To login, click on the right arrow icon to the right-hand side of the
password field, or click on the « Enter » button on the keyboard.
● If your password is correctly entered, the desktop will appear after a
short delay.
● If you see an error message, click on the password field and re-enter
your password, making sure that you enter each number carefully. Then
repeat step 5.

10.1.4 Procedure for Shutting Down the Tablet

The Tablet can be shut down in three ways: 
a. Sleep - this option puts the Tablet into « sleep » mode, which means that
the screen and hard disk are switched o but the Tablet remains in a
state that uses very little power.
b. Hibernate - the Tablet saves all the information about currently running
programs in a file before it switches itself o . When the Tablet is switched
on again it will restore all programs exactly as they were before the
Tablet was switched o . The main advantage of using this mode is that
the tablet takes less time to boot up when restarting, and there is  no
need to restart programs that were running when the hibernate mode
was used. The tablet does not use any electricity when it has been
switched o using this mode.
c. Power O - The Tablet will be completely switched o in this mode. To
conserve battery power, it is recommended that the “Sleep” mode be
used to shut down the Tablet. if it is likely to be restarted within two hours
(for example, during the day when carrying out interviews). If the Tablet
will not be used in the next two hours, it is better to use the “Shut down”
option.

Page | 73
 To power o the Tablet, the first step is to: 
a) Quit the Tablet Menu using the “Exit” option in the Menu.
b) Hard press on the power button on the right side of the Tablet 
c) Press turn o on the Tablet to Power O

10.2 Dashboard
A Dashboard is a visual display of all of your data. The Data Quality Manager
(DQM) will use the Dashboard to monitor the flow of data on the field. It is
designed to have a quick view of the activities in the field as regards data
collection, streaming and storage. It is built with specific indicators which
measure the performance of the Enumerators and evaluate technical workflow.
There are two types of Dashboard; (i) Spatial Dashboard and (ii) Statistical
Dashboard.
i. Spatial Dashboard: The spatial dashboard is for reflecting cumulative
synchronised data and Map view also for download of the data in csv.
ii. Statistical Dashboard: Statistical dashboard displays records, hence it is
possible to track enumeration progress or confirm if all enumerators
actually synchronise.

10.3 Troubleshooting
In this session, we are going to look at the basic techniques of troubleshooting
any Tablet that will be used for census operations. Troubleshooting simply
involves the process of identifying, isolating and resolving a software or
hardware related fault within a PDA. The best way to avoid fault is to take
preventive measures in handling PDAs.

Page | 74
10.3.1. Preventive Measures to be Taken While Using the PDA
Unauthorised external storage devices are not allowed into the PDA ;
a. The  PDA is exclusively reserved for Census activities, therefore do not
pimp the PDA (install unapproved memory card, audios or movies,
software and mobile applications)
b. Do not run a program alongside the Census Apps. example running
system or program updates when the Census Application is in use.
c. Do not connect the PDA to internet via unknown Wi-Fi (free or paid
wireless internet access)
d. The PDA will be strictly used for the census operation, videoing and
unauthorised snapping of pictures with the PDA is prohibited.
e. Application crash issues should be reported to the Supervisor
immediately.  Do not PANIC!
f. Do not allow the PDA battery to drain completely; use a Power Bank
(backup).
g. Keep the PDA away from liquid substances like water, tea and drinks of
any sort.
h. Always leave the PDA in its pouch to protect the screen in case of
accidental dropping.
i. Do not attempt to fix or take the PDA away from the field for repair
without the notice or permission of the DQM because of the sensitivity of
the Census Data.
j. Do not use an incompatible power adapter (charger) in the  PDA.

10.3.2. PDA not Turning On Causes:

a. Stuck in power o mode: When you turn o your
Tablet at some point and try to turn it back on, your
Tablet may have lagged and frozen in the power-o
or sleep mode.
b. Battery out of charge: Your PDA may be out of
charge and you did not realise it or in some cases the
power rating display misread the level of charge your
PDA has.
These problems can be resolved in the following ways: 
a. Connect your PDA to the power source for 10 minutes then try powering
to resolve the problem.

Page | 75
 b. Do a force starting by pressing a volume down button and power button
at the same time for 10 seconds.
c. Check out the charging port, the PDA, the charger head and the USB
cable.

10.3.3. PDA not Completing Booting Process

This is when a PDA is stuck on the start-up screen or restarts continuously
without a complete booting process. 
This could be caused by:  
a. This problem can be caused by temporary system software malfunction.
b. Unfinished system software update
To resolve the problem:
1. Restart the PDA and repeat the system software update to the end.
2. Booting in safe mode: it involves powering the device o and then
powering it on by holding the power button and a set of other keys
depending on the make of the Tablet.
3. If the problem is still not solved by now, that implies that you can't fix it
by yourself, contact your Supervisor!

10.3.4. PDA Not Charging

 This could be caused by: 
a. Faulty USB Port
b. Damaged USB Cable
c. Damaged or incompatible power adapter (charger)
To resolve these problems: 
a. Change the USB Cable.
b. Check and replace Power Adapter
c. Try another power source
d. If the problem is still not solved by now, that implies that you can't fix it
by yourself, contact your Supervisor.   

10.3.5 Unresponsive Touch Screen Causes:

a. Physical damage of touch screen
b. Dust or improper calibration
c. Touch screen responding incorrectly. For example – you
are typing ‘q’, but you get ‘w’.

Page | 76
 d. Touch screen lags/freezes/hangs.
e. Part of the screen doesn’t work.
These problems could be resolve through the following ways:
a. Wipe the screen with a soft microfiber cloth. Clean o any dirt, dust or
fingerprints on the screen.
b. Replacing the screen Touch calibration.
c. Remove the plastic touch screen protector sheet. Some protector sheets
are too thick and prevent the touch screen 
d. from responding to your tap.
e. Dry your hands thoroughly. The touch screen will not respond if your
fingers are wet.

10.3.6. PDA Soaked by Rain or fell into Water

Do not turn it on if it is o or use it in any way.
a. Do not press on any buttons or keys.
b. Do not shake, tap or bang the tablet.
c. Do not disassemble the PDA, else it could void the warranty, the device
comes with a Liquid Damage Indicator (LDI), this could be triggered when
you open the PDA.
d. Do not try to blow on it. This could send water into other internal parts of
the Tablet which haven’t been reached yet, causing more damage in the
process.
Solutions
Turn it o as soon as possible and keep it in an upright position.
a. Remove the protective casing if you have one around
it.
b. If the water damage is more extensive, you can use a
vacuum or hand dryer to carefully suck out water
stuck within the cracks that are harder to get at.
Bury it in a Zip locked bag full of uncooked rice. This may
seem odd to you, but rice is great at absorbing liquid and is
actually a common practice for drying smartphones and
Tablets. It has been  tested and proven    

Page | 77
10.3.7 PDA Not Connecting to the Internet
Download of EA by the enumerators and submission of house numbering and
house listing as well as enumeration data requires network connectivity.
Enumerator’s Tablet has been equipped with SIM cards which will provide
mobile data connection. As the enumerator moves around his/her EA, the
mobile-data signal can change. In fact, he/she may observe the status bar icon
change from 4G to 3G to even 2G or — worse — nothing, depending on the
strength and availability of the mobile data service. These are some of the
troubleshooting tips that the enumerator should carry out.
Causes:
a. Limited or No internet connectivity from the Internet Service Provider
(ISP)
b. No network coverage or low signal strength
c. Data connection not turned on
d. No active data subscription
Solutions
a. Restart your device. It might sound simple, but sometimes that's all it
takes to fix a bad connection.
b. If restarting doesn't work, switch between Wi-Fi and mobile data
c. Check that mobile data is turned on and you have a data connection.
d. Turn flight mode On and O
e. If you still have problems after you complete these steps, contact the
Supervisor

 CHAPTER ELEVEN
INTRODUCTION TO COMPUTER-ASSISTED PERSONAL INTERVIEWING (CAPI)
OPERATIONS

11.1 Introduction
This Chapter will introduce the major operations of the Computer Assisted
Personal Interviewing (CAPI) for the 2023 Population and Housing Census (PHC)
as it concerns the roles and responsibilities of enumerators. Enumerators are
sets of field functionaries responsible for collecting data on the field using the
Personal Digital Assistants (PDAs) and report directly to the field supervisors.
Computer-aided interviewing techniques are most likely to be new to some
enumerators, particularly those in the rural areas. It is therefore important to
understand how to ask questions and deal with problems arising from
interviews and fieldwork using this new technology. This chapter  basically
explains how to record responses correctly and follow instructions given by the
computer.

11.2 Census Enumeration Tools

A hybrid digital tool has been developed for the collection of data during the
census. One part of the hybrid system is the CensusPad which handles the
Geo-spatial component of the system and is used for building numbering and
household listing. Some features and application of the App include;
1. EA Assignment
2. Map Fetching 
3. Georeferencing and Geocoding
4. Location of Area of Assignment

geo-points, might not have been identified within your assignment area Once
completed return to the provisioning menu to proceed with the next step.

11.3.6 Fetch Base Map

The basemap is the satellite imagery that shows the
earth's surface related to your assignment area This
is required that you do it once for the purpose of
o ine access. To do this, click on the
FETCH BASE MAP button. This opens a window
that shows the polygon (your Assignment Area). The
app automatically fetches the base map around your
polygon first before other areas. Once satisfied that
the map is clear enough for work, click on I HAVE
LOADED MY BASE MAP AREA. Once all parts of your
basemap are downloaded successfully, kindly go
back to the provisioning menu.

11.3.7 Check CSENTRY Status

request that you install the CSEntry and it initiates
this automatically. If you encounter issues at this
stage, refer to your supervisor immediately.

11.3.8 Get Census Resources

Aside from the physical materials that you have with
you, you are provided with resources materials that
can be readily available during the course of your
field work as a reference material. You can select from all available useful
resources such as manuals, video explainers and graphics supporting the
census activities to use a sa reference material in cases where you need
clarification in the field

11.3.9 Taking the Oath of Secrecy

To ensure that confidentiality is
enforced and you abide by the rules
and regulation of the exercise, you are
expected to take the second oath of
secrecy.
Enumerators are required to read and
accept the oath of secrecy to keep all
respondent responses confidential and
correctly record all information provided to them at all times.
Once this process is completed, you would have successfully provisioned our
tablet for the commencement of field work. You should not return to the main
menu Page for the next task
11.3.10 Census Task and Goals
Once provisioning has been archived, Enumerators
are expected to move to the Census Task and
Goals section to access all required census tasks
and progress across Household Listing, Census
Night and Census Enumeration.

Page | 83
11.3.11 Select your Enumeration Area

Click on the “Select Enumeration Area” drop

down
Select your Fetched EA from the drop down list.
Example ; BABA GONBE KORODUMA KARU
Where your Area of assignment has more than
one polygon (i.e Multi-Locality EA) downloaded
during the provisioning stage, you will see all the
polygons that exist in your EA in the drop down.
Select anyone you want to view the details about or navigate to.

11.3.12 Locating your EA

In order to ensure enumerators find their EA starting point fast and accurately,
the CensusPad provides a navigation feature which detects the enumerator's
current position and also the location of the
selected EA. The censusPad generates a route
which is then displayed on Google map. It is
important that the GPS on your device is on at
all times. To use this feature click on NAVIGATE
TO EA and a pop up will show.

Page | 84
Click on the PROCEED to Generate a Route. This
action will take you to the Google map interface
On Google maps, enumerators can see the
estimated time needed to locate the beginning of
their enumeration area if they use a car, bike or trek
on foot.
Click on Start to get a responsive direction.
This informs you on how to get from your current
location to your Enumeration area. Follow the paths
or roads .If you are using a bike or a car, direct your
drive with the right turns so as to get you to your
assigned area easily. Once this is completed please
return back to the CensusPAD Application
When back in CensusPAd, verify that the name of the area is the same with the
name on your EA summary. ALso you will have to use what you have learnt in
Map interpretation here to identity structures by the size, association, colour,
etc. if in dot refer to the chapter on Maps Interpretation.

11.4 General Instructions on CS Entry

11.5 Concepts and Terms in CSEntry

CSEntry is the Application used to run data entry on devices such as phones or
tablets. It is also a data collection tool available as an Android application. For
the 2023 PHC it is the main Individual enumeration application.
1. ICONS: An Icon is a graphic symbol, usually a small picture which is used
to represent a file or application stored on you r PDA.
2. CASE: This is a Household type selected for Enumeration.
3. DATA SYNCHRONISATION: Also known as Data Sync. It is the process of
uploading and downloading data to the Server. It involves sending and
replication of the data collected from the enumeration process to a
centralized database.
4. RADIO BUTTON: A radio button is a small circle with a solid circle in it,
which allows the user to choose ONLY one option.

Page | 92
 5. CHECKBOX: Is a tick box that permits the user to make multiple options.
For example, the user may have to answer 'yes' (checked) or 'no' (not
checked) on a simple yes/no question.
6. OPEN TEXT: This is a field that permits the user to enter alphanumeric
text in the space provided.
7. PRE-FILLED: Fields that are automatically populated/filled.
8.  BLUE LETTER WORDS: Information for the enumerator only
9.  RED LETTER WORDS: Vital information to be strictly adhered to by the
enumerator.
10. When the age is not known after probing use 99
11. Any age above 90 years is recorded as 90

 CHAPTER TWELVE
GENERAL LISTING AND ENUMERATION PROCEDURES

12.1 Enumeration Procedures

In Chapter 2, you learnt how you should approach your work, how to conduct
yourself and how to do an interview. In Chapter 3, you learnt the definitions of
census terms and some basic census concepts. How to complete the Building
Numbering and Household listing and related field exercise was taught in
Chapter 4. How to ask each question and how to enter the information given to
you by the respondent on the census forms in the PDA, will be learnt in this
Chapter. Chapter 9 discusses the census questions and how to complete the
Census Questionnaire (Form NPC01). The procedure to follow under some more
diverse interview situations is also discussed. After going through this chapter,
you should be able to administer each question in Form NPC01 properly and
accurately and select/record the responses in appropriate columns/spaces
provided in the PDA.

12.2 Refreshing your Memory

Before starting enumeration, you should have completed the Building
numbering and household listing form NPC07. You should not have forgotten
your lessons on how to approach and relate to the respondents. You should
also have determined the main type of population in your EA: regular
population, institutional or special.
While completing NPC07, you listed the buildings and compounds following the
most convenient order. Use the same order, for commencing the interview. The
Building numbering in your PDA is your guide to help you to visit all households
and interview all persons systematically without omission or duplication.
You must complete the enumeration within 5 days’ period from 29th March to
2nd April, 2023. Organise yourself and your visits such that you are able to
enumerate all persons in your EA within the census period.

12.3 Enumeration units and some precautions to be observed before and

during enumeration
Remember that this Manual of Instructions will be your reliable helper as you
commence and do your work. You should always take it along when you are
enumerating because you will need it any time when in di culty.

Page | 115
The unit of enumeration for the Population questions is the individual in a
household and for the Housing questions, it is the housing unit. An additional
unit of enumeration in which persons will be identified is the household. For
Institutional households, the unit is the hall, dormitory, ward, cells, etc., of
residence. For the homeless and transient persons, it is the location they are
found at the time of enumeration.
Arrangements have been made to interview the census functionaries in their
assigned Enumeration Areas.
After completing the enumeration of every individual in the household, apply
indelible ink at the base of the left thumbnail (or right in case the left is
unfortunately missing). Indelible Ink leaves behind a non-erasable ink mark,
thereby making it di cult to be removed by any person and get counted more
than once. Before you begin an interview, you must check the left (or right)
thumbnail of every respondent to avoid double counting.
Note: Enumeration and other work done by you will be subjected to quality
checks during the field work through intense and unannounced visits and
supervision, as well as online monitoring.
Re-interview will also be conducted by the supervisors to ensure the quality of
your work. If you or your colleagues are found defaulting, penal action will
follow.

12.4 Enumeration Procedure

The Enumeration Procedure during 2023 PHC will be by canvasser method. You
go from one building to the other and from one household to the other
interviewing each household and individuals physically present. Procedures for
enumerating di erent household types are highlighted below:

12..4.1 Procedure for enumerating a Regular Household and Diplomatic

corps.
● Greet, introduce yourself and read out the Confidentiality statement “My
name is.................. I am working with the National Population Commission. I
have been assigned to work in this area in the ongoing population and
housing census.”
● Identify the head of the household or any adult member of the
household and ask for their permission to start enumeration in the
household. You cannot list any other household members without
identifying the head of household and information on age, sex and

Page | 116
 relationship to head on each person’s listed in the household will be
collected immediately.
● Ask also how many people slept in the household the previous night,
including guests and visitors and usual members of the household who
are present but did not sleep in the household previous night.
● Check for the presence of each of the persons stated; they are present if
you physically see them. Ensure that you include in the roster only those
you see physically.
● Ask if there are other members who are not physically present but will be
back before the end of the Census reference period. Leave a call back
card for other usual members who have been mentioned but are not
physically present at the time of your visit.
● Interview every person in the household one after the other.
Note: On no account should you accept to record information for those who are
not physically present in the household at the time of your visit or commence
enumeration before the midnight of the census day or continue enumeration
after the last day set for enumeration nationwide. To help youdetermine the
order of enumerating persons in the household, find below some guidelines:
● Interview the head of household and record his/her information on the
PDA
● Interview the spouse and then Co-wives if any:
● Interview the children one after the other.
● Interview other members of the household with visitors and guests, if
eligible.
All members of a household are not necessarily related by blood or marriage
because house helps and visitors may be part of a household. On the other
hand, not all related persons living in the same building/house or compound
are necessarily members of the same household. For example, a father and his
married children are not necessarily members of the same household; it
depends on their catering arrangements and acknowledgment of the head.
Thus, in many cases, a house/building or compound may be divided into
separate households.
● When multiple generations live in the same building you should not
assume the grandfather, his married children and their families (i.e., his
grandchildren) as necessarily forming one household. Care must be
taken to di erentiate the households unless they insist, they are one
household with one head. Proper explanation would make respondents

Page | 117
 understand that there is no intention of ‘breaking’ the family but the
intention is to know their living arrangement and size of household for
various development parameters.
● You may also come across a compound with more than one building
(secondary housing unit in the same compound) where the husband and
his wives live in di erent housing units. This is an example of one
household with multiple housing units.
● In a compound with more than one building where the husband and his
wives live in the same housing units and other married or grown up
children live as household in other housing units, the children should be
captured as di erent households.
● Where one or more of the wives live in housing units outside the
compound, such should be treated as di erent households and the
woman becomes the head of household.
Generally, the first row is used for the head of household. Sometimes, it is
advisable to respect the order of enumeration suggested by the head of
household or as the members present themselves to you. The names of
married children who do not normally reside in the household and are sure to
return to their own households before the end of enumeration period should be
excluded. Where any of the married children live with their family in the same
household with the parents, and they all recognize the father as the head of
household, particulars of such an extended family may be recorded if they
have not been enumerated elsewhere (Check their thumb nails for indelible ink
mark by way of precaution).
Ensure that no member of the household is left out and no member is recorded
more than once by checking the left thumb for the presence of indelible ink.
After having interviewed a member of the household, you mark the left thumb
with indelible ink.

12.4.2 Procedure for enumerating other Household types

Household Types in this category include: institutional (long and short stay),
Census functionaries and Floating/Transient Population)
● Greet, introduce yourself and read out the Confidentiality statement “My
name is.................. I am working with the National Population Commission. I
have been assigned to work in this area in the ongoing population and
housing census.”
● Interview every person as you see them

Page | 118
 ● Click next to wrap up when every person has been interviewed.
Note: In general, institutional households are found in:
1. Educational Institutions: Examples are: hostels in boarding schools,
universities, training colleges, boarding schools for the handicapped,
orphanages, boarding nurseries, and religious schools.
2. Homes for the sick: Examples are hospitals (including psychiatric,
maternity homes), herbalist and divine healers’ centres.
3. Rehabilitation centres: Examples are correctional centres, Borstal/
remand homes and schools.
4. Service Barracks: Examples are army camps, military academics, police
and other paramilitary training schools and colleges.
Note: In the categories mentioned above, Regular Households can still be found
within institutions for example sta quarters. When a family (father, mother or
children) are found in an institutional building, enumerate every person
separately.
Note: Enumerate only such visitors who would not go back to their usual
residence within the period of enumeration.
Do not enumerate casual visitors; casual visitors normally reside within the
same locality and will not spend the night with their host.
Do not enumerate married children who do not normally reside in the
household and will return to their own households before the end of
enumeration period.
When dealing with “Other Specify”, ensure that you have looked through all the
options provided and do not find the appropriate response. Also, state in brief
and with correct spelling what you are specifying.
Ensure that all instructions are duly followed.
The 2023 PHC seeks to ensure that all persons and buildings in the country are
enumerated. However, it is could be realized that access to some institutions
such as military barracks, police barracks, correctional facilities, health facilities,
boarding houses, rehabilitation centres, etc. are restricted, while it is imperative
to have their occupants and inmates enumerated during the census.
Enumerators and Supervisors should acknowledge that gaining access to
enumerate the occupants and inmates of these institutions will require special
approval from their managing authorities. Supervisors should identify such
institutions within their SAs early enough, preferably immediately at the end of

Page | 119
their training and plan on how to request for permission to access them. This is
because some of the institutions will need su cient time to process the request
at their headquarters. They should liaise with the Field Coordinator and LGA
Comptroller to arrange and dispatch letters of request for permission to gain
access into the facilities to enumerate the buildings and persons residing in
them. It is worthy to note that some of these institutions have special protocol
procedures, as such you are expected to be conversant with them and strictly
observe them while processing the request.

 CHAPTER THIRTEEN
ESTIMATION OF AGE AND DATES OF KEY EVENTS

13.1 Introduction
Age is simply defined as the number of years we reached at our last birthday
which is used as a marker for “biological age”. Age is a very important variable
in any demographic endeavour for meaningful analysis. Age Estimation is the
task of estimating the age of a person from whichever scientifically verifiable
means available and allowable.

13.2 Why is age data important?

13.2.1 Practical Life Application

Age is used to determine eligibility for the under-listed among others;
● Schooling
● Marriage
● Medical purposes
● Employment
● Driving & Voting

13.2.2 Surveys, Censuses & PES Questions€

Age of respondent will determine eligibility to participate in surveys (e.g in the
DHS, questions on reproduction and fertility are administered on women 15-49
years old). Some questions that will be administered during the 2023 PHC and
the Post Enumeration Survey (PES) are age specific, for example questions on
schooling and marital status.

13.2.3 Demographic Analysis

Data on population age structure provide the basis for many types of
demographic analysis. E.g., age is an important variable in the study of
mortality, fertility and migration.

13.2.4 Development Indicators

Age provides an important context in the analysis of important development
indicators such as number of schools, health facilities established, analysis of
labour supply, etc.

Page | 121
13.3 Sources of Data
Age data can be derived mainly from traditional or non-traditional sources:

13.3.1 Traditional Source

The traditional sources are:
1. Periodic census or enumeration
2. Sample surveys or inquiries
3. Vital registration systems
4. Population Registers.

13.3.2 Non-Traditional Sources

These are administrative records of demographic data gathered and processed
by government agencies such as: School registers, Hospital records,
Employment registers, Church/Mosque registers, Tax registers, Licensing o ce,
Police records, etc.

13.4 Methods of Age Determination

There are several ways to determine the age of respondents if he/she does not
know. These include:
1. Asking the respondent (if an adult) who may know his/her age
2. Asking respondent’s parents or other family members who may know
his/her age (for younger persons).
3. Use of respondent’s personal documents (Birth Certificate, Voters Card
etc.)
4. Use of Respondent’s peers (born around the same period).
5. Use of Historical Events Calendar, which should be the last resort and to
be used after exhausting other avenues of obtaining the respondent’s
age including the use of personal documents.

13.5 Age Consistency Determination

There are 3 major methods to be used in determining the age consistency of
the respondents;

13.5.1 The Arithmetic Method

The arithmetic method requires that you first calculate the sum of the year of
birth and the age. Apply one of the following rules to determine if these
responses are consistent. 

Page | 122
IF BOTH MONTH AND YEAR ARE KNOWN
If the month of birth is before the month of Census (the respondent has had her
birthday
this year), then his/her age plus the year of birth should equal the year of
Census [2023]. 
Example: A respondent tells you that he/she was born in January [1978] and is
45 years old during Census (2023). His/her responses are consistent, since the
month of birth is (January) which is before the Census month (April) and the
year of birth [1978] and age (45) sum to the year of interview [2023]. Also,
another respondent tells you that he/she was born in July [1999] and said
he/she is 24 years old. Her/his responses are inconsistent, the month of birth
(July) is before the month of Census (April).
However below are also some examples that the enumerator can use to verify
the age of the respondents easily.
If the year of birth is reported by the respondent, ask if he/she celebrated
birthday in the current year, then subtract the year of birth from the current
year which is the year enumeration is taking place.
Example; if a respondent’s birthday is Feb 1999, Had celebrated birthday in the
current year as at time of visit of the enumerator in the household, subtract
year of birth from the current year.
Age = 2023-1999 = 24 years
Example; if a respondent’s birthday is October 1999,
Not yet celebrated birthday in current year, subtract year of birth from last
year
Age= 2022-1999 = 23years
If respondent does not know his/her age and year of birth is not reported,
enumerator will have to probe further;
Ask the respondent how old he/she was during the first marriage or had his/her
first child, try to estimate the age from the information given to you on this.
Example; if she says she was 18 years when she had her first child who is now 10
years old, probably she is now (18 +10=28 years) at the time of enumeration.
Also, if the respondent could not remember the month when she was born, it is
su cient to subtract the year of birth from the current year [2023].

Page | 123
 Try to relate age to someone in the household or in the compound whose age is
known. 

13.5.2 Chart Method

You may use the Age/Birth-Date Consistency Chart (as shown below) to check
the consistency of the information the respondent provides. In using the chart,
you will choose one of two approaches,
IF BOTH MONTH AND YEAR ARE KNOWN
If the month of birth is before the month of interview (the respondents already
had his/her birthday this year), use the right-hand column to see what year of
birth is consistent with that age.
If the month of birth is after the month of interview (she has not yet had her
birthday this year), use the left-hand column to see what year of birth is
consistent with that age.
IF ONLY YEAR OF BIRTH IS KNOWN
If the respondent mentions the year of birth listed on the chart which is not
consistent in either the left or right-hand column of the chart, then the
enumerator needs to probe to ensure that the age is consistent with either the
left or right-hand column by using the historical event calendar.

13.6 Historical Events Calendar Method

The Historical Events Calendar is used to help estimate ages of respondents
who do not know their ages. The Calendar is critical in estimating age as
respondents who could not remember their age after all e orts have been
made, will be asked about events that must have happened when they were
born.
The List of Historical Events assists the Enumerators in avoiding as much as
possible rough guesses of respondents’ age and enables them to check
respondent’s answers on age. That is, if the enumerator has exhausted all other
means to obtain the respondents age, he/she can refer to the Historical Events
Calendar and try to determine how old he/she was at the time of an important
event such as a war, flood, earthquake, change in political regime, etc. and add
the age at that time to the number of years that have passed since the event.

Fig. 13.1 Graphical explanation of the di erence between Historical Events and
the Historical Events Calendar
Page | 126
 13.7 Methodology of Compiling Historical Events Calendar

13.7..1 Data CollectionQualitative data collection method was used.

1. Free-listing interview with relevant stakeholders (The older persons
disaggregated into retired civil/public servants, traditional rulers,
religious leaders etc).
2. Free listing of historical events was elicited from the discussants.
3. Verification and validation of H/E data collected.

13.7.2 Collation
The listed events were collated and arranged by place and year of occurrence
and arranged from International, National, Regional through to Local Events.

13.8. Using Historical Events Calendar

The events in the calendar are arranged according to place and year of
occurrence. The estimated age is also included to make calculation easier.
The enumerator simply has to ask the respondent that does not know his/her
age what events they may have been told had occurred around the year of
their birth.
The enumerator would go to the events calendar and pick the corresponding
estimated age of the respondents.
Example: A respondent that says she doesn't know her age but that she is sure
she was born in the year of Nigeria’s Independence you look for the year of
occurrence which is 1960. The corresponding age on the chart is 62 years. 
Points To Note When Using Historical Events Calendar, 
● The Historical Events Calendar is to be used after exhausting other
means of obtaining the respondent’s age.
● You use the Historical Events Calendar by asking the respondent what
historical event occurred around the time of their Birth/ Marriage/etc
and then picking the corresponding estimated age. 
Page | 128
 ● It is possible that the events may not have occurred exactly on the year
of the respondent’s birthday. In that case, adjust and calculate
accordingly.
Example; In our example, Nigeria’s Independence celebration may have
happened when the respondent was 5 years old. In that case, it would mean she
was 5 years old in 1960, making her year of birth 1955. That would make her 67
years today.

 CHAPTER FOURTEEN
INSTRUCTIONS FOR COMPLETING BUILDING NUMBERING AND HOUSEHOLD
LISTING QUESTIONNAIRE
The aim of this chapter is to introduce you to what you will be doing after you
have been trained and assigned an EA. At the end of this chapter, you should
understand how to identify your EA of assignment, update and conduct building
numbering and household listing in your EA of assignment.
Materials to be used for building numbering and household listing include:
1. Digital Enumeration Area (EA) Map in the PDA
2. Building numbering and Household-listing form (NPC07) in the PDA
3. Biros, Notepad Chalk/Marker and/or House-numbering Stickers/Bag

14.1 Enumeration Area

During the Enumeration Area Demarcation exercise, the entire country was
subdivided into small units called Enumeration Areas (EAs) using Geographic
Information System (GIS). It is necessary to fetch and confirm your Enumeration
Area where internet service is available. Correct identification of EA of
assignment must precede Building numbering and Household listing. EA
identification is aimed at ensuring that:
● You know the precise geographical area of your assignment.
● You do not miss any area or part of your assignment.

14.2 EA Maps
Recall that in chapter 3 a detailed discussion on various maps was done. For the
Household listing, the EA map is what primarily concerns you as an enumerator
The EA map for an enumerator may contain one or more polygons. Where an
enumerator has one EA polygon map, it means he is working within one locality.
Where the EA assigned to an enumerator comprises more than one locality, the
enumerator will have more than one polygon, one for each of the locality that
makes up the EA.

14.3 Household listing form Questionnaire Identification Section

Questionnaire Identifiers is like the name by which a person or an object is
known. It will be easier to trace a lost person if s/he has a name or bears some
unique characteristics. They are needed to group the Census data from
individual units to larger units such as Enumeration Areas, Localities, Wards,
LGAs, and States.
Page | 130
The identifiers have names and codes, using the PDA, in most cases the
identifiers are prefilled after proper profiling (fetching of EA maps/imageries)
with your PDA. While in some instances you will be required to select the correct
identifiers that relate to your EA from a pre-coded list of drop down. Note that
the codes may not be visible to you but are associated with the name you
select at the back end.
Among the identifier for household listing are:
ZONAL NAME & CODE: This is the geopolitical zone of the EA you have fetched.
STATE NAME & CODE: This is the name of the State where enumeration is being
conducted. The State Code is a two-digit numeric number given to the State
during demarcation.
LGA NAME & CODE: This is the name of the Local Government in the state where
enumeration is being conducted. The Local Government code is a three-digit
numeric number given to the local government during demarcation.
WARD NAME & CODE: This is the name of the ward in local government where
enumeration is being conducted. The ward code is a five-digit number given to
the ward during demarcation.
LOCALITY NAME & CODE: This is the name of the locality where enumeration is
being conducted. The locality code is a five-digit number given to the locality
during demarcation.
ENUMERATION AREA NAME & CODE: This is the name of the Enumeration Area
(EA) where enumeration is being conducted. The EA code is a seven-digit
number given to the EA during demarcation.
RURAL AND URBAN CODE: This is the classification of an enumeration area
been in either rural setting.
ADDRESS OR NAME OF OWNER OF BUILDING: This is the physical address of
the structure that is being listed. In Nigeria, there are areas that do not have
conventional addressing systems, in that case it is advised that the name of the
owner of the structure should be used and nearby prominent feature should be
used in identifying the building.. This field is pre filled but is editable in case the
address collected during demarcation has changed or was incorrect.
ENUMERATION ID: This is the unique identity of the Enumeration Area polygon
assigned to you.

Page | 131
Note: These EA identifiers are pre-filled, that is, the CAPI will prompt them
automatically for the Enumerator when s/he use their correct phone number
registered for the Census to fetch it

14.4. Confidentiality Statement

An Enumerator must read out the confidentiality statement in the questionnaire
at the start of listing each household; if there is a doubt by any member of the
household, an enumerator should emphasise that the information to be
obtained is confidential and will only be used for statistical purposes.

14.5 Procedure for Enumeration Area Identification

In order to ensure that enumerators find their EA starting point fast and
accurately, the CensusPad provides a navigation feature which detects the
enumerator's current position and also the location of the selected EA. The
censusPad generates a route which is then displayed on Google map.
For steps on how to get to your assigned EA Using the ‘Generate Route Icon’
refer to Chapter 5.

14.6 Map Updating

This is the process of adding information about new features such as new
buildings, roads, mast, other prominent features points, Floating populations
points, found on the ground to the digital map, and correcting names, spellings
of features on the map. This process also allows you to mark structures and
features that are no longer in existence. The update will be added to the
database.

14.7 Building numbering/Household-Listing

All structures identified during the EAD have been numbered and the numbers
will be displayed against each building on your digital map. It is these numbers
on your digital map that will be transferred to the physical buildings on ground.
a. If a structure on the digital map is still on ground but not numbered on
the map, click on “add building” icon for the building to be auto
numbered. Then transfer the auto generated number to the physical
building on ground.
b. If a structure is currently exiting on ground but not on the digital map,
stand at the position where the building is found and click on the “add
building” icon to add and auto number to the structure. Then transfer the
auto generated number to the physical building on ground.

Page | 132
 c. If a building seen on the digital map is no longer existing on ground, tap
on the no longer existing building on the digital map and select “no
longer existing” to mark the building. as demolished
As you verify and physically number each structure, you proceed to add a
household to the buildings (if it is a residential building) before moving to the
next structure.

14.8 Labelling of House-Numbering Stickers

Write the building number on the sticker or walls starting with CENSUS 2023/
followed by the digital number of the building on the digital map for example, if
the number of a building in the digital map is 006, then the entry on the sticker
should be CENSUS 2023/006. The sticker should be pasted on the doorpost,
gate or any other well visible place, about six feet from the ground so that it will
be out of reach of children. Do this for all buildings/ within the Enumeration
Area. However, in case of lack of stickers or if stickers cannot be pasted on
rough walls, use, chalk/maker for putting numbers on buildings in a
conspicuous place as mentioned above.
Complete the listing of all households in a building before you go to the next
building.

14.9 Listing of Structures

In Form NPC 07, existing and new structures should be classified under any of
the following levels of completion
1. Fully completed
2. Completely roofed but uncompleted
3. Partially roofed
4. Roofing level [with improvised roof]
5. Lintel level [with improvised roof]
6. Roofing level [without roof]
7. Lintel level [without roof]
8. Window level
9. Damp-Proof Course (DPC) level
Listing of structures in a multi locality EA should be done for all Localities that
are attached to the EA. If an Enumerator’s area of assignment had 4 EA Maps
(localities) that make up the EA, s/he must fill the forms for all the structures
within each of the localities.

Page | 133
1410 Contents of the Building numbering Form
Every structure must be listed, buildings are represented with building points on
the map as shown in the PDA. These building points come with building numbers
that were given during the demarcation. The enumerator is not to recreate a
new building number but to leverage on the existing number. In a case where
the enumerator sees a new structure, s/he should use the “ADD BUILDING “icon
to capture the building.

 CHAPTER FIFTEEN
INSTRUCTIONS FOR COMPLETING PERSONS ENUMERATION QUESTIONNAIRE
(Form NPC01)
The main census questionnaire (Form NPC 01) will be used to collect information
from respondents; the questionnaire is embedded in the Personal Digital
Assistant (PDA). It is important to note that the Enumerator is only allowed to
collect information from persons who are physically present. The Questionnaire
Identification particulars are preloaded, however, crosscheck to ensure you are
in the right EA.

It is important to always read the instructions given in the questionnaire before

proceeding to ask questions. Also, endeavor to read carefully any message
that pops up on the PDA while you are conducting an interview. Specific
instructions to Enumerators are highlighted in capital letters, and are indicated
in red color.These sets of instructions are for the consumption of Enumerators
only, and are not to be read out to the respondents. At the end of this chapter,
you should be familiar with all the questions, how to ask questions correctly
and how to record the responses on the PDA.
15.1 Sections of the Questionnaire
The NPC 01 Comprises of identification particulars and 10 other sections under
two categories;

15.1.1 Persons Characteristics

1. Demographic and Social Characteristics
2. Migration and Displacement

15.4 DATE OF INTERVIEW AND NUMBER OF VISIT:

This refers to the date and time you conduct an interview in a household. The
number of visits made before the interview is completed should be recorded.
Several visits should be made to the household to ensure that all members of
the household are enumerated. If no other member of the household is found

15.9 Demographic and Social Characteristics
In this section, information on demographic and social characteristics of
members of the household will be collected. The socio-demographic questions
are to be administered to all household members. Enumerators should
remember that enumeration usually starts with the head of the household
where s/he is available. The following scenarios are likely to occur during
enumeration:

Scenario Description Solution

Remember, where the head of the household is not available and will not be
available throughout the census period, the next member in line who can stand
in place of the head of household should assume the status of the household
head.However, if the head of household is temporarily unavailable and
expected to return within the census period, leave a callback card for the
household. You are required to revisit the household and enumerate the
household, but ensure that no member of the household has been previously
Page | 153
enumerated outside the household. After completing the enumeration of a
household, proceed to the next household. Remember that you are to record
only answers supplied by the respondents themselves except where the
respondent is too
young to supply an answer or is incapacitated. Continue until all households
and persons in the EA assigned to you are completely enumerated.Do not rely
on information provided by any other person except for children or
incapacitated persons who cannot express themselves verbally or in writing. In
the institutional household, start enumeration with anybody available.

QUESTION Explanation/response category

Write the full name of the respondent starting from first

P1. What is your full name, then the middle name, and the surname last. All
name? names must be typed correctly without titles such as
“Mr”, “Madam”, “and Alhaji” or Chief. Do not enter initials.
For example, for Mrs. OLANIPEKUN, EVELYN ARINOLA, the
first name is EVELYN, the middle name is ARINOLA and
the surname is OLANIPEKUN (as shown in the boxes
below).For someone without a middle name e.g
ELIZABETH IDOKO, the first name is ELIZABETH and the
surname is IDOKO (see boxes below). Abbreviated names
like IDOKO, E is not allowed. A child without name at the
time of enumeration should be recorded as NOT YET
NAMED. In areas where the surname of the wife is the
name of her husband, proceed as follows: if the surname
of the husband is ABDUL, and his other name is
SULAIMAN, then the surname of the wife and children will
be SULAIMAN.In some other areas, the surname of wife
and children is the surname of the husband/father. For
example, if the name of the husband is JALINGO INUWA,
with INUWA being the surname, then the wife and all
children will bear INUWA as their surname. In general,
enumerators should adopt whatever practice that is
prevailing in the locality.

First Name Middle Name Surname

Evelyn Arinola Olanipekun

For ELIZABETH IDOKO, this name does not have a Middle

name. The first name is Elizabeth and the surname is
Idoko
First Name Middle Name Surname
Elizabeth Idoko

 Every respondent must have his/her sex recorded.
P2. What is your sex? Observe and record the sex of the respondent. When you
are in doubt of the sex of the respondent, do not hesitate
to ask. Be careful in dealing with babies and young

same goes with the dresses.
P3. What is your age in The Enumerator should collect information concerning
completed years? the age of the respondent in completed years as at last
birthday. For example:
RECORD AGE 1. If a child is 1 year and 11 months old, record 01
year for the child.This is because the child has not
AS AT LAST celebrated his/her second birthday.
BIRTHDAY. 2. For an infant less than one-year-old, who is one
week, three months, or eleven months, you type
00 in both boxes because the child has not yet
lived one completed year.
3. Probe further for every respondent who reports
age ending in 0 or 5, as there is a tendency to
report age ending in digits 0 and 5 and thereby
distorting the age data.
4. Many people, particularly in rural areas, may not
know their exact age. Make the best estimate of
their ages by using the list of historical events
given to you.
5. Ask more probing questions for every respondent
who states that as at the time he/she was born
there were no records.
6. If after using the historical event and you are
unable to establish the respondent’s age, use
your good sense of judgment, as a last resort, to
estimate the age. You should do your best to
ensure that the age of the respondent is recorded
in all instances.
7. If age is 95 years and above, record 95. see
details on Chapter 8.
The date of birth of a respondent is the day, month and
P4. What is your date of year the person was born irrespective of the place where
birth? respondent was born. It should be in the format
Day/Month/Year. If the day is not known, fill in 99. The
calendar is preloaded in the PDA for the enumerator to
select the respondent’s date of birth appropriately. In
some cases, you may rely on historical events to
determine the date of birth.

If the day is unknown, record “99”, but the month and

year of birth must be recorded. Probe to obtain month

Page | 155
 and year of birth. If the month is unknown, record
“January” for births that occurred between January and
June, and record “July” for births that occurred from July
to December.

of Household? be male or female. Record how each person in the
household is related to the head of household. Example;
(ASK ALL PERSONS IN If FASIKU is the head of household, and he has a male
child named Nnamdi, then Fasiku’s relationship to the
HOUSEHOLD)
head of household is “the head of household”. Nnamdi’s

15.10 Literacy and Education
Literacy and formal education are two key socio-demographic indicators.
Literacy focuses on the ability to read and write in any language with
understanding while formal education refers to the process of acquiring
knowledge and skills in a structured school system. Formal education refers to
a structured and graded form of education system that runs from primary and
in some situations from nursery) school to university, and includes specialised
programmes for vocational, technical and professional training.
Questions on literacy (P25 and P26) are to be asked of persons 6 years and
older. The purpose of these questions relate to the individual's ability to read
and write in any language. Note that a respondent is considered literate if s/he
can read and write a simple statement with understanding. Literacy is more
than the ability to write or distinguish between the various letters of the
alphabet and counting numbers. Questions on education are not to be asked of
people who are younger than three years old.
The Table below presents the questions on literacy and education; it also
contains a detailed explanation of each question.
Questions Explanation/response category
P25. Can you read and write in any There are three options to be selected for
language with understanding? this question;
1 = Yes, read and write,
2 = Yes, read only (i.e. read but can’t write),
3 = No cannot read nor write.
Code ‘1’ should be selected for someone who
can read and write in any language and
code ‘2’ for someone who can read only but
cannot write in any language Skip to P27 if
code ‘3’ is selected.
P26. In what language can (Name) read This question should be asked from
and write with understanding? respondents whose response to question P25
is ‘Yes, can read and write’ (code 1), find out
from the respondent the language s/he can
read and write with understanding. If s/he
can read and write in more than one
language, select the language that the
respondent understands most. If P25 is ‘Yes,
can read only’ (code 2), find out the
language that the respondent can read with
understanding.
P27. What is your current schooling This question seeks to determine the
status? schooling status of the respondent at the
time of enumeration and is applicable to
Page | 167
 respondents aged 3 years and older. School
here refers to any formal educational
institution.
There are three response options out of
which the respondent must belong to one;
1= Attending now: Select the option
‘attending now’ if the person is still receiving
full-time education at the time of the Census
Night. This includes those who are on
vacation at the time of the Census Night and
would be going back to school
2= Attended in the past but not now: Select
the option ‘Attended in the past’ if the person
received full time education in the past and is
no longer receiving as at the time
ofenumeration. If attended in the past but
not now skip to P.29
3= Never attended: Select the option ‘never
attended’ if the person has never attended
formal education if you select option ‘Never
attended’, skip to P31.
P28. Is the institution you are currently This question has five options to be selected
attending Public or Private or other from, namely;
organisations? 1= Public: An institution whose management
is run by public or government sector
2= Public/Private: This is an institution whose
management is shared between Public and
Private Sector,
3= Private only: An institution whose
management is run by private organisation
only
4= Religious Agencies: These are Institutions
that are wholly owned by religious
organisations,
5=Corporate body/Agency: These are
Institutions that are owned by other
corporate organisations either for profit or
corporate social responsibilities. Select the
appropriate response for the respondent.
P29. What is the highest level of This question seeks to elicit information on
schooling you are attending the highest level of formal school respondent
now/attended in the past attended or is attending. Note that the
interest here is to find the highest level of
formal schooling respondent ever attended
or attending and NOT completed. If a
respondent dropped out of school at a level,
it means s/he has attended that level. Fifteen
levels of schooling have been identified and

Page | 168
 the enumerator must select the level that
best describes the respondent’s response.
The fifteen response categories are;
1= Basic literacy: This is equivalent to primary
1-3 of the formal system which provides
reading, writing, numeracy, and skills for
adults and youths who did not have an
opportunity for formal education. Basic
literacy lasts between 6-9 months.
2= Post literacy: This is equivalent to primary
4-6 of the formal system and organised for
graduates of basic literacy who want to
acquire more knowledge and for those who
for one reason or the other dropped-out
from formal school between primary 1-3. The
post-literacy stage usually lasts for 2-3
years. From this level, a learner can proceed
for further education either through the
formal or open and distance learning
system.
3= Nursery
4= Kindergarten
5= Primary
6= Junior Secondary school
7= Senior secondary school
8=Vocational/Technical/Commercial
9= Post-Secondary Diploma and OND
10= Tertiary-HND
11= Tertiary-Bachelor's degree
12=Tertiary-Post graduate
certificate/Diploma
13= Tertiary- Professional certificate
14= Tertiary- Master’s Degree
15= Tertiary- PhD
P30. What is the highest grade (form, The highest grade/class/form completed, is
class/level, etc), you have completed at the last full class, form or year COMPLETED
that level of schooling? and not the present/current one being
attended. For example, if the person is
currently in primary five (5), then the highest
grade/class completed will be Primary four
(4) since s/he has not yet completed Primary
five (5). Similarly, a child who is currently in
JSS 1 or who dropped out during the second
term in JSS 1, will have "0" (Zero) recorded,
because no grade/class has been completed
at that level. Record the equivalent
grade/class for persons who have attained
some level of schooling through distant or

Page | 169
 correspondence education. If the grade is
unobtainable, the equivalence of the number
of years devoted to that particular type of
school will provide the required information.

15.12 Economic Characteristics

The 2023 PHC would be one of the main sources of labour statistics, which are
important elements in the measurement of economic growth and development
in the country. Labour statistics are used in the analysis, evaluation, and
monitoring of the labour market; governmental and non-governmental policies
(relating in particular to employment, income support and industrial relations);
and population groups of particular concern (e.g. younger people, older people,
and women). Users of labour statistics include government and their agencies
and advisers, economists, financial analysts, journalists, business people, trade
unions, employer associations, students, and academic researchers.

15.7.1 Economically active persons

This section deals with the economic characteristics of the respondent. It
intends to determine the activity that the respondent engaged in or did not
engage in seven days before the census night that involves the combination of
resources (capital goods, labour, etc.) to produce specific goods or services. It is
applicable to respondents who are 5 years and older at the time of
enumeration.

Question Explanation/Response Category

P36. During the 7 days The question seeks to determine if the respondent
preceding the Census Night, was engaged in any economic activity even if it was
did you engage in any for one hour within the seven days before the
economic activity, for at census night. Being an economic activity, it is
least one hour? (i.e since expected that if the respondent engaged in an
22ndof March, 2023, did you economic activity within the period, s/he should be
work?) rewarded. However the reward could be in cash or

Page | 175
1= Yes, worked for pay (cash or in-kind): This
category includes all those who worked for pay
(either in cash or in kind). The pay does not
necessarily mean that the person has received the
pay but if the person worked and is expecting a pay
later, then the person should be classified under this
category. In-kind payment means that the individual
either received or is expected to receive a form of
payment which is other than cash. For instance, as
his salary, a worker may be paid two bags of rice or
an amount of money plus an item every month.
Included in this category are people who sell and
get profits or commission on what they sell. Note
that persons who are learning trade (apprentices)
and receive pay should also be classified under this

some remuneration (cash or in-kind) in the past 7
days, even if the work was performed for at least
one hour and skip to P39 (1).
2= Yes, worked for profit in own/family business:
This category includes all those who worked in
own/family business in producing goods and
services for profit (either in cash or in kind). The
profit may be received later or may have been
received already. Also included in this category are
persons who worked in their own business or in
family business by selling goods and services for
profits or commission on what they sell. Select
option ‘2’ and skip to P39 (2).
3= Yes, engaged in economic activity, but received
no pay/profit: this category refers to people who
engaged in some economic activity during the 7
days before the Census Night, but did not receive
any remuneration for the work done. Note that this
excludes those who are expected to receive
payment for work done later. Included in this
category are persons who are learning trade
(apprentices) and receive no pay. For those who
worked and did not receive pay record ‘3’ and skip
to P39 (3).
4= Yes, worked in own agricultural activity:
Engagement in "agricultural activity" means any of
the following:
a. Any activity directly related to the production of

Page | 176
 crops;

or livestock;
c. Any activity directly related to the cultivation or
harvesting of trees;
d. Any activity directly related to fish farming; and
e. Other agricultural activities such as Bee keeping,
snail farming, among others.
If a respondent says he/she worked on his/her farm
during the 7 days before the Census Night, record
option ‘4’, skip to P13c and choose option ‘6’, then
proceed to ask P39 (4).

5= No: This refers to persons who did not work (did

not engage in any economic activity) within the
reference period. Included in this category are those
who had work but for some reasons did not work
within the reference period but would definitely go
back to work after the short break. Examples are
persons who were on leave or strike and expected
to go back to work after the break. For those who
did not work in the reference period, continue to P13
(5).

P37. During the 7 days

preceding the Census Night, This question seeks to determine the manner or way
how were you mainly the respondent was mainly engaged since s/he
engaged? reported that s/he did not work within the seven
days preceding the census night. There are four
options the enumerator can select from:
1= Available and seeking work. This is a situation
where the respondent is not working but intends to
work and also seeking for work. If code 1 is selected,
skip to P45
2= Available AND NOT seeking work. This is a
situation where the respondent is not working but
does not intend to work and also not seeking for
work
3= Not available for work. This is a situation where
the respondent cannot work even if s/he is o ered
a job because s/he is currently being engaged with
something e.g study, sickness, etc.
4= Has work to go back to. This is a situation where
the respondent did not work during the period and
Page | 177
 is also not seeking for work because s/he has the
work that s/he will return to. If code 4 is selected,
Skip to P39.
The respondent may be temporarily absent from
work for reasons such as:
▪ Being on leave/without pay (e.g.
people on study leave, maternity leave
with or without pay, etc)
▪ O -season (e.g. farmers or fishermen
who did not do any work because it
was their o -season).
▪ Temporarily ill with/without pay: (e.g
workers on sick leave or on admission

asked to stop work temporarily as a
result of lack of raw materials,
breakdown of equipment, high cost of
production, etc.

mudslide, bad road, persistent rains,
etc)
P38. Why were you not There are respondents who did not work within the 7
working or seeking for days preceding the census night. The question seeks
work? to find out the reason for their in activity during the

reason for his/her inactivity which is not in the 13
options, select option 14 and specify.

1= Did home duties (homemaker)

Page | 178
 2= In full time education /student
3= Pensioner/Retired
4= Disability condition
5= Sick and unable to work
6= Too old/Aged

8= Don't need to work
9= Pregnancy/delivery
10= Discouraged/frustrated
11= Wage too Low/not attractive
12= There is no work
13= No qualification/skill
14= Other Specify.........

P39. Does [NAME] have a The question is to be asked of people engaged in

work contract/agreement? employment work only and seeks to know if there
was a mutual agreement on the terms and
conditions of the work between the employer and
the employee, either written or oral (verbal). It
should be noted that signing “a written contract”
also includes a letter of employment/appointment
in which the respondent’s wage/salary has been
specified, otherwise, there is no contract signed.
That is, if the letter of appointment does not specify
pay and other conditions of work. Select the
appropriate option from the list of response
categories.
1= Written agreement with undetermined duration: A
written agreement with undetermined duration is
when the contract between the employer and the
employee has no fixed term of engagement. In the
2023 PHC, ‘Written agreement with undetermined
duration’ is an employment contract made between
workers and an employer which both parties agree
upon without setting a specific ending date.
2= Written agreement with fixed duration: A written
agreement with fixed duration is when the contract
between the employer and the employee has a
fixed term of engagement. For example, the
agreement could be working for a company for up
to 2 years after which he/she parts with the
company.
3= Verbal agreement: A verbal agreement is when
Page | 179
 there is a verbal contractual agreement between
the employer and the employee. This means that
there is no documentation on the agreement that
was reached between the employer and the
employee
4= No: A ‘no’ response is when the respondent
indicates that there was no agreement, whether
written or verbal between the employer and the
employee.
P40. IF WORKED IN LAST 7 The focus of this question is to find out how many
DAYS, ASK: hours the respondent in total, spent on economic

IF DID NOT WORK IN LAST 7 Census Night, and calculate the total weekly hours
DAYS, ASK: of work. It is important to mention that the interest
How many hours did you is to record the hours of e ective work and not the
usually devote to this number of hours the respondent spent at the
activity per week? workplace. Therefore, exclude hours paid for but the
respondent did not work such as meal breaks and
commuting time.
Record the number of hours that the respondent
was active in the last 7 days preceding the Census
Night.
Note: that there are 24 hours within a day and care
should be taken such that the respondent does not
seem to spend all his/her time on engagement of
economic activities or possibly spending more than
24 hours on work within a day. For example, if on a
particular day, the respondent was at the workplace
at 8 a.m. in the morning and left at 5 p.m. in the
evening, do not necessarily record 9 hours of work
for that day. Probe to find out how many hours
he/she actually worked on that day. It is possible to
find that the respondent stayed out of work for 1
hour and 30 minutes and therefore hours of work
for that day should be 71 /2 hours. Similarly, if a
farmer sets o at 5 a.m. to her farm and it takes 2
hours to walk before work actually starts, then the 2
hours should not be counted as hours of work.
P41. What type of work did This question intends to classify the work done in
you do in the 7 days the 7 days preceding the census night into
preceding the Census night? occupational groups. Select from the dropdown the
appropriate occupation for the work done by the

select others and specify the occupation mentioned
by the respondent.
P42. In which of these This question seeks to classify work done in the last
industries did you work in 7 days into industry. Select from the dropdown the
the last 7 days? industry the work belongs to. If none of the
industries on the list is applicable tothe respondent,
the enumerator should select others and specify the
occupation mentioned by the respondent.
P43. What was your The question intends to find out the employment
employment status in that status of the respondent in the organisation where
establishment s/he worked within the 7 days preceding the census
/business/industry? night.
1= Employee: The respondent is employed on a
regular basis in the public or private sector and
receives payment in cash or kind; it
could be piece rate or time rate.

15.9 Fertility and Child Survival

Fertility is a key component of population change (the others are mortality and
migration) and the main driver of population growth. Complete and accurate
data on births and deaths of children are used to generate various fertility and
child survival indicators which support the e ective implementation of
population and development programmes and general decision making. The
data are also important for determining the burden and distribution of social
services such as educational and health facilities. The census provides an
opportunity to obtain disaggregated fertility data at various levels such as
National, Geo-political zone, State and Local government area. Census data on
fertility and child survival will complement available administrative and survey

Page | 185
data in computing key fertility and child survival indicators. This section
describes the fertility behaviour of females 10 years and older. It seeks to find
out the total number of children (male and female) ever born alive by females
10 years and older and the survival status of their children as well as the age of
the mother at birth of her first child born alive. It also collects information on
the last live births by women aged 10-54 years. This module serves as a source
of data for fertility and child survival indicators to monitor the population
growth and development dynamics.

15.9.1 Definitions
● Live birth: A live birth is defined as the complete expulsion or extraction
from its mother of a product of conception, irrespective of the duration
of the pregnancy, which after separation, cried, breathed, or showed any
other evidence of life, such as the beating of the heart, pulsation of the
umbilical cord, definite movement of voluntary muscles, whether or not
the umbilical cord has been cut or the placenta is attached.
● Stillbirth/foetal death: It is a birth where the baby is born with no sign of
life at or after 28 weeks (7 months) of gestation. Technically, it refers to
the disappearance of life before the expulsion or extraction from its
mother of a product of conception. Questions on Children ever born and
children surviving are described in the table below.
The inclusion criteria are:
1. All females aged 10 years and older should respond to questions P52 to
P55
2. All females aged 10-54 years should respond to questions P56 to P59

miscarriages, or abortions. You should record the number
of all live births of the female concerned by sex and in
two (2) digits. Note that multiple births such as twins must
be recorded as two (2) children. If the female concerned
has not had any live birth during her lifetime, you should
record 00 in the boxes provided. The total number of birth
should be equal to the total number of biological children
of the women living in the household plus the total
number living elsewhere and the total number of death

15.11 Instructions for Completing Household Level QUestions

This chapter introduces the housing module of the NPC 01 questionnaire. This
part of the questionnaire is devoted to collecting information on deaths of
household members in the last 12 months; housing characteristics and
amenities. It is concerned with conditions and household facilities in occupied
buildings. Questions on household characteristics range from H1 to H13 and the
Housing Sanitation Questions from S1 to S6.

15.12 Purpose of the Household Level Questions

These questions are meant to gather information on deaths in the household as
well as on deceased females aged 10 to 54, including questions on pregnancy
related deaths. Questions on housing characteristics and amenities are
intended to collect data on the quantity and quality of housing in Nigeria as well
as on the availability of some essential amenities in the buildings and essential
facilities in the households. Information to be collected include materials for
construction of the wall, floor and roof, number of rooms occupied by each
household, type of dwelling, essential amenities available (power, and water
supply, waste disposal, toilet etc.) and essential facilities available in households
or accessible to household members e.g., radio, television, telephone, etc.
Enumerators are expected to ensure that all instructions are strictly followed so
as to collect high quality data. Such information is indispensable to planners
and policy makers in evaluating housing conditions, estimating housing needs
and formulating housing policies.
Explanations on how to administer these questions and how to record
responses correctly are provided in this chapter. Remember that all housing
questions relate to households and should as much as possible be answered by
heads of households. In their absence, other adult members of the household
can provide answers. Assure respondents that information supplied will be
treated as confidential.
Therefore, the objective of this chapter is to:

Page | 189
 1. Introduce the Household Deaths section (Mortality)
2. Introduce the housing and amenities questions;
3. Housing Sanitation, and
4. Explain how to administer each of the housing questions.

15.14. The Household Characteristics and Amenities Question

It is assumed that you have concluded enumerating the head (or at least one
adult member) of the household and that you are ready to administer
questions on housing. Politely draw back the attention of the head of household
to this part of the questionnaire. It is assumed that you had earlier told the head
to expect your calling on him/her back for this purpose. These questions are to
be answered by the head of the household or any other adult member
assigned to do so by the head on his/her behalf. Enumerators are however
reminded of the need to be very observant and be prepared to probe where

Page | 191
they doubt the respondent's answer. For instance, where you suspect the floor
finishing to be wood and it is reported as terrazzo, the enumerator may have to
politely request the head to unveil the rug that may be covering the floor for
confirmation.

15.15 How to Administer the Housing Questions

This section explains each of the questions in more detail.

H1 Type of Building
What type of structure is the household occupying? This refers to the type of
residence occupied by the households as at the time of the census
enumeration.
In a residential house occupied by a regular household during the census
enumeration. It could be a building or some form of shelter arranged for human
habitation and occupied by the household. Some structures may serve more
than one purpose. In some cases, people live in the building and some of the
rooms serve as o ces or shops where people transact their business or
sell their goods during the day. In as much as regular households live in such a
structure, it should be classified as a housing unit and select 1. Note that if the

of human habitation not included in the categories above select ‘5, and specify
the nature of habitation.
It is only a household living in a housing unit (i.e., coded ‘1’ in (H1) that will be
required to provide answers to the remaining housing questions (H2 to H13). For
households whose living quarter during the enumeration period is coded ‘2’ to ‘’;
in H1, go to H9A. QUESTIONS H2 TO H13 ARE TO BE COMPLETED FOR
HOUSEHOLDS LIVING IN HOUSING UNIT ONLY (i.e., H1 IS CODED 1)

H2 Type of housing unit

What type of housing unit is the household occupying? The purpose of this
question is to identify the type of dwelling unit occupied by the household in the
building or structure during the census enumeration period.

Any other habitation should be indicated as others and the enumerator should
select 9 and specify.

H3 Sleeping Rooms
How many sleeping rooms are available to this household? This question seeks
to determine the total number of sleeping rooms occupied by the household.
The enumerator should ask the head of the household how many rooms the
household occupies in the building for sleeping. Note that rooms to be included
are the space under exclusive use by the entire members of the household for
sleeping. This excludes the sitting room, dining room, kitchen, store, toilet and
bathroom. If, however, any of these utility rooms has been converted and is
currently being used as a sleeping room, such utility rooms qualify as part of
the sleeping room. This question must be clearly explained to the respondent to
enable the enumerator to get a reliable answer. (Enter as reported by the
respondent).
Questions H4 to H13 are designed to collect information on types of material
used for constructing the housing unit being occupied by the household. If there
is more than one type of material, record the main material: that is, the material
that covers the larger part of the housing unit. Select the appropriate option
based on your observation. Also, it is expected that through mere observation,
the enumerator will know the type of material used for the construction of the
housing unit. In some instances, direct observation will not be possible, the
enumerator is expected to ask from the respondent any time there is doubt as
to the type of material used for the finishing.

H4 Floor (Finish)
What is the main construction material used for the floor of this dwelling?
Record the material used for the finishing of the floor of the housing unit (living
quarters) occupied by the household. For example, the finishing of the sitting

such instances the material that is used for the major part of the dwelling
should be recorded. Select the applicable material among the options listed.
Where the materials used are not included in the list, select 9 and specify the
material in the space provided. This should be done by observation, but ask if in
doubt,

What is the main construction material used for the roof of this dwelling? This is
not a question that you will have to ask the respondent since you will be able to
see for yourself the kind of materials used for the roofing, however, ask if you
are not sure. If there are more than one type of material, record the main
material that is used in roofing the larger part of the housing unit. Select the
material in options 1-8 listed. Where the material used is not among those listed
in 1-8, select 9 and specify the material used in the space provided.

 CHAPTER SIXTEEN
ENUMERATING SPECIAL POPULATIONS
This Chapter focuses on how to enumerate Special Populations. Special
Populations are identified groups based on demographic or other specific traits,
who require special consideration or attention during enumeration. 

16.1. Population that Require Special Attention

The Special Population groups are:
a. Homeless Persons
b. Homeless Households
c. Nomadic Households
d. Transient Population
e. Fishing and Hunting Populations
f. Women in Purdah
g. Foreigners within the country
h. O shore Workers
i. Field/Camp Populations
j. Internally Displaced Persons (IDPs)
k. Refugees

16.2 Enumerating Special Populations

Di erent techniques are employed to enumerate populations in each of these
categories during a Census because of their special characteristics and
peculiarities. These techniques and methods are explained fully below. Regular
and institutional households are not considered a special population.
Institutional households can be in special institutions like correctional centres,
mental homes, hospitals, barracks (field camps), etc. 
Since there may be restrictions on entering these institutions, the heads of these
institutions are usually called upon for permission to enumerate their occupants
(that is persons in their care). In some cases, these institutions provide their own
sta that will assist enumerators in approaching the occupants for the purpose
of enumeration. Please do not hesitate to seek their cooperation for
enumeration purposes. In case of any di culty, please contact your Supervisor.
The Commission conducted a pilot mapping of pockets, clusters and locations
of all special population groups in every part of the country. Each special
population group listed in Section 16.1 belongs to an EA (form part of an EA).
Information on location, characteristics, etc. of each special population group
Page | 214
will be loaded as an additional layer on the EA map in the CensusPad.
Enumerators should check for the existence of any special population groups in
their EAs immediately after they fetch their assigned EAs from the CensusPad.
Special populations will be enumerated as part of the EA they belong to.
Women in purdah, though considered as a type of special population, are
usually found in a regular household setting.

16.2.1 Homeless Persons

Homeless persons include beggars, vagrants and lunatics who are usually
found in public places. Places where homeless people sleep may include
bridges, parks and marketplaces. You should ask community leaders and NGOs
for such places during household listing, it is expected that you have identified
and recorded the places where homeless people sleep at night. Homeless
persons will be enumerated on the first night of the Census (after 12:00
midnight). It is therefore necessary to go round at night and familiarise yourself
with the places during the building numbering and household listing. For that,
you may need protection from relevant authorities. Do not approach the
homeless persons alone for security reasons.
List the homeless persons continuously as you listed members of the
institutional household. Use your initiative as an enumerator to complete the
questionnaire for them where they are unable to provide answers by
themselves or consult local leaders. Use your best sense of judgement to
estimate their ages in case it is di cult to obtain the same.

16.2.2 Homeless Households

Homeless households have to be enumerated as regular households. Homeless
households are identical to regular households except that they have no fixed
place of abode. Complete forms for each homeless household separately, just
as you did for regular households. Remember also that homeless households
can be made up of one or more members.

16.2.3 Nomadic Households

These are persons who move from place to place in search of pasture for their
animals. Nomads do not settle in any one place for a longer period. Some stay
in a place for only a few days. Their settlements may not have been indicated
on your EA map because they may not have been there during EA demarcation.
Those recorded on the EA map may no longer be there. Check their thumbs to
confirm that they have not been enumerated and proceed to enumerate them.

Page | 215
Nomads must not be confused with other Cattle Rearers who are settled in one
location for a longer time (more than two years). Their cattle move out but
return later in the day or after a few days. Suggestions for approaching and
enumerating nomads include:
1. Use of Government Agents, Representatives of veterinary/sanitary sta
or any other government agency associated with the nomads enjoy the
confidence of cattle breeders and will usually cooperate with them.
It is important to be familiar with the culture of the nomads. For example,
the Fulanis do not normally give out the names of their first son, first
daughter, first son-in-law, first wife, etc. Do not put pressure on a
respondent who does not give such names. Other members of the family
may be willing to give them.
2. Use of Tribal or Traditional Leadership Structure: Nomads usually take
direction from their heads or leaders. To obtain information from them,
you can use their leaders. 
3. Camp Approach: The camps where Nomads are living must have been
identified and listed during building numbering and household listing. You
should approach Nomads in such camps and enumerate them.

16.2.4 Transient Populations

Transient Population refers to persons and/or households that are not likely to
return to a regular or an institutional household within the enumeration period.
They include persons or households that are on the move and cannot be
assigned to any specific building. During household listing you have identified
and recorded the places where the transient population can be found. They are
found at international borders, airports, sea ports and motor parks. Only
international transit persons should be enumerated at seaports, international
airports and border towns, usually on the move. Domestic transit passengers at
local airports, train stations, motor-parks etc., should be counted at their places
of destination.
All international transit persons should be enumerated continuously on a
questionnaire just like you enumerate an institutional household.

16.2.5 Fishing and Hunting Population

Fishing and hunting are seasonal occupations in many communities. The
fishermen and hunters spend days on water or in the bush during the season.
Fishermen normally bring their crafts/boats to anchor at particular points,

Page | 216
while hunters bring their catch to a nearby village for sale. Enumeration should
be carried out at such concentration points.

16.2.6 Census Functionaries

Like all other persons residing in Nigeria, census functionaries should be
enumerated. They will be enumerated under household type “Census
Functionaries”. Each team of Enumerators should be enumerated in their EA of
assignment while other functionaries (such Supervisor, Coordinator, DQM,
Monitors, etc) should attach themself to an EA within their area of assignment
for enumeration.

16.2.7 Women in Purdah

Female enumerators should enumerate women in purdah, as males
enumerators may not be allowed into their courtyards. In case the enumeration
team consists of only male enumerators, permission of the head of household
or assistance of the community leaders must be sought in advance. In such
circumstances, be more careful to respect, and follow, the cultural practices and
with a little tact and commitment you should be able to win the confidence of
the head of household or community leader, which will allow you to enumerate
women in purdah with ease.

16.2.8 Foreigners within the Country

Since we are carrying out a de-facto Census, persons of any nationality
physically seen in Nigeria are to be enumerated. All foreigners staying in Nigeria
during the census period will thus be enumerated just like other citizens
wherever they are found in the Enumeration Area. 

16.2.9 O shore Workers

O shore workers are both Nigerian citizens and non-Nigerians working on the
high seas who will not return to their usual place of residence throughout the
enumeration period. These are for example members of sta of oil companies
drilling crude oil on the high sea. They should be enumerated with the help of
dockworkers who should provide the means of reaching such workers. The
State Directors/Comptrollers should contact the o cials of the companies in
advance to assist in ensuring that all persons working on the territorial waters
of the country are enumerated. O shore workers on the high sea should be
enumerated as institutional households.

Page | 217
16.2.10 Field/Camp Population
The field/camp population includes:
I. Soldiers on bush-exercise
II. Miners in the field
The field/camp population are enumerated on the first day of the census but
enumeration may not necessarily start from midnight. Seek the permission of
the camp leaders before the enumeration day.

16.2.11 Internally Displaced Persons (IDPs)

Internally displaced persons were forced to move from their usual place of
residence to live temporarily in another place within the country, as a result of
violence, communal clashes, famine, Government policies or natural disaster.
You enumerate them in the same manner as homeless persons or households.

16.2.12 Refugees
These are persons who are unable or unwilling to return to their country of
origin owing to a well-founded fear of being persecuted for reasons of race,
religion, nationality, membership of a particular social group, or political
opinion. Refugees who are in camp are to be enumerated as institutional
households while those who are integrated in communities will be remunerated
as regular households.

 CHAPTER SEVENTEEN
RE-INTERVIEW SURVEY

17.1. INTRODUCTION
There are errors but the same cannot be said of non-sampling errors, which
can occur at every stage of data collection (Planning, field operation, tabulation
and computation). Unlike the sampling error, which decreases with increased
sample size, non-sampling errors increase with increase in sample size. This
means that non saData collection through complete enumeration (Census) can
be free from sampling sampling errors are expected to be higher in census than
in surveys. It is for this reason that re-interview is necessary to minimise
non-sampling errors.

17.1.1. What is re-interview survey?

A Re-interview Survey is another innovative quality assurance layer that will be
implemented during the 2023 PHC. It is an evaluation tool for assessing the level
Page | 219
of compliance to the protocol by the Enumerators and checking the accuracy
of data they collected right on the field. It entails the visiting of Supervisors to
selected buildings and households to observe how enumerators conduct live
interviews and, re-administer some key census questions after enumeration is
completed in the households. Buildings and households that will participate in
the Re-interview Survey will be randomly selected. This survey is centred more
on checking for content errors than coverage errors, although it may to some
extent determine coverage errors.

17.2 Re-Interview Methodology

The Re- interview Survey will be conducted in two stages:

I. During Building numbering and household listing
II. During persons’ enumeration

17.2.1 During Building Numbering and Household Listing

The first stage of Re-interview Survey will be carried out during building
numbering and household listing. Three buildings shall be selected randomly
from buildings where listing has been completed through an automated sample
selection process. The selection shall be based on a moving universe with the
daily interviews of the enumerators serving as universe. Example of a sampling
universe is presented in Table 13.1 below.

Table 17.1: Example of a sampling universe

SN DAYS BUILDINGS NUMBERED UNIVERSE SAMPLE

1 1 25 -

2 2 40 25 1

3 3 15 40 1

4 4 33 15 1

It can be seen that each day forms a new universe for sample selection. During
this period, the re-interview is to be carried out by the supervisors and the unit of

Page | 220
re-interview shall be the building.It shall start on the second day of enumeration;
this is because the first day shall be used for sit-in interviews by the supervisor i.e.
staying with a set of enumerators and observing them conducting interviews. In
an SA the supervisor is expected to carry out the re-interview in fifteen (15)
buildings within three days in an SA with five EAs. This means one building per EA
per day as shown in the re-interview matrix below. In order to ensure that the
execution of the process is done early enough and remedial and corrective
decisions are taken, the re-interview shall take place in the first four days of
building numbering and listing as follows: Day 2, 3 and 5. A Building re-interview
Matrix for the 2023 PHC is presented in Table 13.2 below.

Table 17.2: 2023 PHC Building Re-interview Matrix

Day 5 BL 3 BL 3 BL3 BL 3 BL 3

Building Re-interview Matrix explained

● Day 1: sit-in interview (supervisor will observe conduct of interviews by
enumerators).
● Day 2: Conduct re-interview in the first selected buildings in all the EAs in
the SA.
● Day 3: Conduct re-interview in the second selected buildings in all the EAs
in the SA.
● Day 4: Observe improvement on corrections made particularly on the
weakest enumerator or set of enumerators.
● Day 5: Conduct re-interview in the third selected buildings in all the EAs in
the SA.

17.2.2. DURING PERSONS’ ENUMERATION

The second stage of the Re-interview Survey will be implemented during

persons’ enumeration. It is also to be carried out by the Supervisor.The
household will be the unit of reinterview and it will start on the second day of
Page | 221
enumeration. Three households shall be randomly selected from the households
that enumeration has been completed through an automated sampling
process. The supervisor is expected to carry out the re-interview in a total of
fifteen (15) households. Re-interviews in the selected households will be
conducted in three numeration days (day 2, day 3 and day 5). All members of
selected households shall be interviewed.
During the reinterview, questions on household characteristics are to be
answered by head of households or any adult member while those on individual
characteristics are to be answered by individuals themselves, except children or
incapacitated members. In a situation where the respondent is not at home at
the time of visit, the supervisor should make a return visit in view of the fact
that the person's enumeration is de-facto. Table 13.3 below presents the
Household Re-interview Matrix for the 2023 PHC.

EAs in the SA.
● Day 4: Observe improvement on corrections made particularly on the
weakest enumerator or set of enumerators.
● Day 5: Conduct re-interview in the third selected households in all the EAs
in the SA.

17.3 GENERATION OF RE-INTERVIEW REPORT
The report from re-interview shall be generated thus:
1. The supervisor syncs the data to the server
2. The server through an algorithm process automatically compares the
data from the supervisor with that of the enumerator
3. The matched items are coded “1” while unmatched items are coded “0”
4. From this the KR-20 report is generated
The report is then sent back to the following:
1. Supervisor’s tablet
2. DQM’s dashboard and mirrors same to the situation room for further
assessment
3. Monitoring App to be accessed by:
a. The Field Coordinator
b. Geo-monitor for supportive decision
Based on the report generated, there are three possible outcomes. The
outcomes and actions the supervisor and other census functionaries should
take when an outcome occurs are explained in Table 17.4 below:

173.1. Guide to field, LGA, State coordinators, Geo-monitors and Situation

Room
A comparison of consistency levels in the SA will determine whether a specific
set of enumerators or the supervisor is probably right or wrong as shown in the
daily report from the SA. The consistency level could manifest one of the
following:
a. ≥80% consistency between the supervisor and the five EAs in the SA
b. 60-80% consistency between the supervisor and the five EAs in the SA
c. ≤60% consistency between the supervisor and the five EAs in the SA

17.3.2 Interpretation of the Enumerator- Supervisor consistency outcome

● The consistency level “a” means all or most of the responses matched
and so the enumerators and the supervisor are right.
Page | 224
 ● The consistency level “b” means some responses matched and some did
not, so some enumerators are wrong or right and the supervisor is wrong
or right
● The consistency level “c” means all or most of the responses did not
match and so all or most of the enumerators are wrong or right and the
supervisor is wrong or right.

17.3.3 Decision Rule if the supervisor is wrong

The Field coordinator upon investigation could find out that the supervisor is
wrong.Three possible reasons that can explain why the supervisor could be
wrong and decision shall be on the possible reason for the supervisor being
wrong:
1. S/he did not attend the training
Decision: Recommend for dismissal and replacement
2. Attended the training but did not understand the concept(s)
Decision: Retrain, coach and watch out for improvement, if no
improvement, where there is no improvement, recommend for dismissal
and replacement.
3. Attended the training understood the concept(s), but is not conducting
the interview according to instructions
Decision: Coach and watch out for improvement.

17.3.4 Conflict resolution mechanism

Disagreement can arise between the enumerators and supervisors for two
reasons
I. The enumerators could reject or deny the report.
II. The supervisor can misinterpret the report
III. When this happens, with the prying eyes of the situation room, the field
coordinator will be expected to wade and resolve the using the
information available to him or her
IV. The Geo-monitor, if available, can also wade in, in exceptional cases. The
decision of the Geo-monitor must be evidence based
V. The situation room should pass judgement where necessary base on the
available information

 CHAPTER EIGHTEEN
DATA QUALITY ASSURANCE FRAMEWORK

18.1 Data Quality Dynamics: Experiences from trial census activities

Achieving acceptable levels of data quality is a major objective of the 2023
PHC. Thus a number of data assurance systems and procedures have been
built into the census process. Experience from the Trial Census showed that
adequate attention needs to be paid to ensure quality in data on sex, age ,
household size, relationship to head of household, marital status, schooling
status and age at first marriage. The Trial Census indicated:
a. A tendency to heap age of respondents with ages ending at 0 and 5. This
may be linked to some challenges in eliciting age data responses but
more likely to the inability of enumerators to probe adequately to obtain
more accurate responses.
b. A bias in sex data in favour of males; thus a tendency to under report
females. Thus might be related to attempts by enumerators to avoid
some fertility and mortality questions related to females
c. A tendency to skip enumeration of some household members. This
resulted in a low value for average household size in the country.
d. That many enumerators did not understand some values (options) in the
relationship to the head of the household data field. This applied
especially to the adopted and foster child values.
e. A poor understanding of the living together value in the marital status
data field. People at very young ages 0,1,2,3, etc were reporting as living
together though the option should apply only to adults in consensual
relationships.
f. Challenges with administering the field on schooling status. For example
there were cases of lower ages reporting currently attending higher
education and very old age currently attending Nursery or early child
education.
g. Some wrong reporting for the age of first marriage data field. There were
cases of age at first marriage being higher than reported age of
respondent.
The above instances indicate, amongst others, the need for enumerators and
other field functionaries to understand and rightly administer all data fields in
census instruments. Thus an important element of data quality assurance
during the 2023 PHC is adequate teaching and learning during training. As such

Page | 226
e ective training of the functionaries is the foundation for the census 2023 data
quality assurance framework. In addition to this, a series of data quality
assurance measures have been entrenched into all facets and levels of the
conduct of the 2023 PHC. For instance, the data quality assurance began with
your recruitment. You recall that you passed through a rigorous screening
process before you were recruited. This was part of the measures that ensured
only competent personnel that can collect quality data were recruited.
Recall also that the DQMs will perform in-depth checks on the data you will
collect during building numbering and household listing as well as enumeration
to ensure that they conform to laid down procedure. Enumerators and
Supervisors will also inject data quality assurance measures by ensuring that all
buildings, households and persons in their areas of assignment are totally
covered during the census. Enumerators should ensure that all persons in a
household are duly enumerated before they leave for another household. They
should ascertain that all persons – old, young, male, female etc. are
enumerated. Household heads should be reminded that newborn babies and
the elderly (who are often ignored during data collection) will be enumerated
during the census.
Care should be taken to ensure that particulars of every person irrespective of
age or sex are recorded separately and accurately. Omission of persons in
households during enumeration is tantamount to undermining the quality of
data that will be collected. For example, it may distort the age and sex
distribution, as well as the average household size. Please note that while every
e ort should be made to avoid omission of persons, it is equally important to
ensure that no person is enumerated more than once.

18.2 A Five Tier Data Quality Assurance Framework

The 2023 PHC incorporates a 5-tier data quality assurance frame involving the
following.
1. CAPI Applications: A hybrid software (CENSUSPAD and CSENTRY) has
been developed for this purpose. As a data quality strategy, the hybrid
software is programmed to perform the following.
a. Ensure complete coverage of all units of data collection.
b. Ensure the safety and integrity of data at the point of collecting
the data
c. Ensure that in built edit specification are functional to allow for
data internal consistency

Page | 227
 d. Ensure that data is encrypted before it is streamed to the server
e. Facilitate the synchronisation of encrypted data to the server
f. Ensure that data that is synchronised is backed in the PDA
g. Ensure that data is safe enroute to the serve and cannot be
intercepted
2. Re-interviews module: A structured reinterview process is built into the
2023 PHC programme. This involves the reinterview of selected
residential units and households by Supervisor. Reinterview will ensure
real time monitoring and quality assurance for the census.
3. Dynamic monitoring through Enumeration Tracking Dashboard and
field Data Quality Management: This is a real-time enumeration tracking
dashboard using computers where data can be tracked real-time or near
real time to ensure full coverage of buildings, households and persons
without direct interference with the data. In other words, data integrity is
guaranteed as only variables or indicators that will ensure complete
enumeration of EAs will be made manifest. It can also be used by the
quality assurance team at the LGA to take corrective decisions to ensure
timely completion of enumeration and collection of quality data.
4. Random spot-checks using geo-monitors and independent monitors
(peer observers)
5. Post Enumeration Survey (PES)

18.3 Other Technological And Methodological Innovations To Assure Data

Quality
The following ICT and geospatial innovations will also enhance the data quality
during the census:
● Cloud computing infrastructure to facilitate mobile data collection and
management
● Collection of highly geo-referenced infrastructure and demographic
(buildings, households, persons) data based on an award-winning
geo-database
● Mapping and geo-tagging of vulnerable population groups (IDPs,
Refugees, pastoralists, farmers, homeless etc.) to ensure their proper
enumeration
● Use of integrated call center service to improve communication among
census operatives and with the public towards ensuring complete and
accurate coverage
● Geo-fencing of buildings and enumeration areas to eliminate fabrication

Page | 228
● Online recruitment portal to ensure recruitment of competent and
adequate functionaries
● Implementation if hybrid learning system that incorporates online or
virtual learning activities to improve participation, understanding and
performance
● Hybrid census methodology to facilitate proper enumeration of
hard-to-reach areas.

 CHAPTER NINETEEN
PRE/POST FIELD ACTIVITIES
Pre-field activities include all preparations made before the take-o of the main
field activities during census. This includes the training of functionaries,
distribution and collection of field equipment and materials, movement to
enumeration areas and community entry and sensitization. Post activities
include withdrawal, retrieval of materials and Post Enumeration Survey (PES)

19.1 Pre Field Activities

Training of Functionaries: A structured arrangement has been put in place for
training of functionaries for the 2023 PHC. Thus it is expected that all
functionaries involved in the census will receive detailed training on conceptual
and practical aspects of their functions.
Post Training Preparations: It is expected that a transitional period- (most likely
one day) will be set aside for preparation for the actual field work. This
transitional period will be used for the following activities:
a. Finalisation of team formation and placement of enumerators to EAs
b. Finalisation of profiling and tablet preparation for field work
c. Distribution of field materials according to teams
d. Engagement with supervisors by planning for field work as follows:
e. Preparation of supervision itinerary by supervisors
f. Preparation of itinerary for re-interview in EAs by supervisors
g. Creation of communication medium (WhatsApp group sms, etc.) by
supervisors
h. Compilation of field o cers list for initial payment of field allowance
i. Finalisation of action plans for enumeration of homeless persons
j. Intensification of advocacy exercise and community entry strategies
k. Engagement of authorities of correctional centres and remand homes for
cooperation
l. Engagement of leadership of orphanage and old people homes for
cooperation
m. Engagement of authorities of prayer camps for cooperation
n. Finalisation of action plans for the enumeration of floating population
o. Ensuring teams have data for synchronising of Data collected on the
field.
p. Departure for field work

Page | 230
19.2 Post field Activities
Two main activities will be carried out post fieldwork namely, retrieval of
materials and clearance of field o cers

19.2.1 Retrieval of material

PDAs and other non-consumable items used during the fieldwork will be
retrieved from the enumerators and other field functionaries. Supervisors will
be responsible for retrieving these materials from the enumerators and
transmission of the same of the same to their coordinators. The materials will
be checked and transmitted through appropriate channels for safe keeping. a
template exists for the retrieval of these materials. This activity should be led by
the DQM at the LGA level and State Coordinator at the State level.

19.2.2 Clearance of Field O cers

A structured mechanism for the clearance of o cers involved in the census is in
place. Supervisors are to clear their enumerators only after ensuring that their
assignments have been satisfactorily completed and their materials returned.
However it is expected that clearance will be done by teams. This means that
no individual member of a team will be cleared finally until the entire team is
cleared. Timely and e ective clearance will facilitate final documentation and
payment of functionaries.

19.3 Post Enumeration Survey

A post enumeration survey will be carried out. This is to measure the coverage
and content error of the 2023 PHC. The PES is organized independently of the
census itself to eliminate bias and ensure accurate and objective assessment.

 CHAPTER TWENTY
TRAINING CENTRE ADMINISTRATION AND MANAGEMENT

20.1. Overview
Training management is one of the most critical factors that would drive the
success of the 2023 Population and housing Census. It Is important to note that
unlike conventional schools, training centres shape skills and familiarise the
Census Workforce to work more supportively in line with the Commission goals.
For the census, training centres are used to develop the skills of the needed
workforce in terms of data collection.This way, they will perform faster, better,
with fewer errors and become e cient resources to the Commission.
The commission will be utilising more than 30,000 classes during the period of
the census and at di erent levels. To support the operational and technical
wing of the census, proper administration and management of these centres
are critical to the success.
The Training Centre Management and Administration unit will
1. aid in e ectively allocating classrooms,
2. ensure the provision of facilities and amenities and the proper
management of the resources making learning convenient for trainers
and trainees.
3. ensure collaboration between the LGA o ce and the training centre
before and during training sessions.
4. ensure e ective distribution of materials to trainees and trainers during
the training sessions.
5. ensure proper coordination during the training sessions.

20.2 Training Centre Administrators

TCM&As manage, coordinate, supervise and facilitate all human and material
resources for the successful training of 2023 Census functionaries across the 36
states of the Federation and FCT.
They provide support for the planning, execution and ensuring free flow of
communication, conduciveness and comfort of the trainees throughout the
training period. They help to meet training goals by mitigating and carrying out
core processes in the training venues.

20.2.1 Roles and Responsibilities

1. Ensuring the prompt opening of classrooms/centres.
Page | 232
 2. Liaise with Cleaners to ensure they clean and tidy classrooms.
3. Ensure that toilet and environment are sanitise on daily basis
4. Support the centre leads in maintaining daily attendance registers.
5. Ensuring all materials needed for the daily work are available and assist
in the Distribution
6. Sending daily reports on activities across various centres to the
headquarters through Online Google Form.
7. Ascertaining performance and deliverables by facilitators.
8. Ascertaining that quality teaching aids are provided at each training
centre.
9. Ensure that quality meals are served and liaise with accounting o cers
for the payment of meal allowances where meals are not served.
10. Liaising with security o cers for the safety of census materials and
personnel.
11. Liaising with the Legal unit and centre lead to arrange for the “Oath of
Secrecy” swearing.
12. Keeping time and maintain orderliness in the training centres
13. Taking and maintaining record of daily proceedings (briefing sessions).
14. 14. Filling the incident form in case of any causality(ies)

20.3 Training Centre Management and Administration

The management of training centres focuses on resource management, trainer
and trainee deployment, quality assurance of the training process and
application of information and communication technologies. The TCMA unit
provides the management and operational sta with administrative support in
their training function during the census.
The training Centre will be the distribution units of the census to the lowest
levels. A training centre will be manned by a Training Centre Administrator
(TCA)and will have 3 centre assistants to support the process. Each centre will
have a maximum of 12 classes, each class will consist of 53 persons i.e 50
trainees and 3 trainers, thus making a centre to have a total of 640
functionaires (including the TCA and TCAAs).
The TCMA unit will focus on 9 areas - training centre environment, standards of
performance, risk management, attendance tracking, sanitation and
cleanliness, logistics and material distribution, daily reporting of work progress,
coordinating of facilitators meetings and preparation for field work.

Page | 233
20.3.1 Training Centre Environment
The training environment is a place where various activities are going on, where
interaction takes place, social situations are enhanced and census beliefs are
imbibed in instructional situations. The training environment plays a vital role in
preparing the minds of the trainees for the task to be carried out in the census.
To ensure that the census is successful, the.training centre environment must be
conducive for trainers and trainees. An ideal training centre should -
1. be well ventilated
2. have electricity within the centre
3. be conducive with good sitting arrangement
4. be easily accessible by trainees and trainers
5. have sanitary facilities like toilets/mobile toiles,dustbins etc
6. have covid materials like face masks, sanitizers etc
7. have hand washing stations
8. have first aid boxes and emergency numbers for health related issues
9. have food vendors within the centre at proper times
10. have good and secured storage facilities within the centre
11. have internet accessibility within the centre

20.3.2 Duties of Facilitators

During a training programme, the trainer's knowledge, experience in
management and training, and personality are the main factors that a ect the
communication process between him/her and the trainees. If that
communication is quickly and easily established then a well chosen training
method would stimulate and facilitate the learning process.
Facilitators have a critical role to play in the management of training centres
especially within their domain (the class). Each class will have a total of 50
students and 3 facilitators. There will be a lead facilitator who will communicate
with the training centre admins in areas regarding the administration of the
centre. The duties of trainers can be found under the Standards of

 CHAPTER TWENTY-ONE
ADMINISTRATION AND LOGISTICS
This chapter will discuss key aspects of the logistics for the 2023 population and
housing census. It is important field functionaries are made aware and
understand the logistics arrangement for the census to help in the performance
of their functions. Logistics arrangement for the 2023 PHC will enable an
e cient workflow of forecasting, inventory management, distribution planning,
reporting, equipment maintenance, and retrieval and incorporate routine data
management processes.

21.1 Work Flow Forecasting

Workflow forecasting will enable projection on sequence of activities involved in
the census. This involves identification of the activities, their timing, material and
personnel needs and the required coordination mechanisms.

21.2 Inventory Management:

A comprehensive list of the materials, equipment and other resources needed
for e ective implementation of the census was made. This has facilitated their
acquisition, deployment and e ective use. Inventory management for the 2023
PHC has taken care of the materials required at each stage of the census
process as well as their storage and security

21.3 Planning for Material Distribution

A well-orchestrated plan is in place for the distribution of materials acquired for
the 2023 PHC. This includes plans for the distribution of PDAs, its accessories
and other field materials required for e ective conduct of the census. A clear
line of distribution from points of acquisition to storage facilities in the States
and Local Government Areas has been mapped out.

21.4 Logistics Administration
A number of functionaries are involved with the administration of logistics for
the 2023 PHC namely national logistics o cer, State logistics o cer and LGA
logistics o cer.

21.5 Logistics Committees

Logistics committees exist at all levels of census administration, namely
National, States and Local Government Areas.

21.5.1 National Logistics O cer:

The national logistics coordinator is overall head of logistic operations during
the census. S/he liaises with the Department of Procurement foe

21.5.2 State Logistics O cer:

The State Logistics O cer is in charge of logistics at the State levels. S/he
collects materials from the headquarters and distributes the same to the Local
Government areas through the LGA logistics o cer.

21.5.3 Local Government Area Logistics O cer:

The function of the LGA Logistics O cer is to coordinate logistics of human
resource and materials within the assigned area. S/he is to ensure the
collection, proper storage, security, distribution of materials during the various
stages of census. This will include distribution of training materials to training
centres during training and during house listing and enumeration.

 CHAPTER TWENTY-TWO
MONITORING AND EVALUATION

22.1 Introduction
This chapter will introduce the enumerators and other census functionaries to
Monitoring and Evaluation in census. To ensure that programmes or activities
proceed as planned and to ensure the success of activities M&E is required.
There is no better place where M&E is required than in census taking. The
Commission has recognised the importance of M&E and has accorded it the
pride of place in the 2023 PHC. Census functionaries are required to understand
the principles of M&E and its conduct for the success of the 2023 census.   

22.2 Concept of Monitoring and Evaluation

Monitoring is a periodic assessment of the progress of a project towards
achievement of its planned activities and results. It starts with the
implementation of the first activity, and continues as long as all activities are
accomplished.
Monitoring is useful for the management to know the status of the project. This
is why it is considered as a basic and universal management tool. Project
management always remains interested to know if the activities are carried out
as per plans, and the activities produce expected e ect on the target
beneficiaries of the project.

22.3 Scope of Monitoring and Evaluation of the 2023 Census

The M&E will focus on all the critical areas towards the 2023 PHC including but
not limited to; 
● Planning
● Pretesting of tools and methodology
● All levels and medium of Training 
● Deployment of personnel 
● Deployment of materials 
● Logistics arrangements
● Building numbering and household listing
● Enumeration
● Post-Enumeration Survey
● Materials retrieval
● Advocacy and publicity activities

22.4 M&E Tools and Methods for the 2023 Census
A combination of complementing tools and methods will be employed for the
M&E of the 2023 PHC.
● Questionnaires
● Field interviews and 
● Observations will form key tools of M&E for the PHC. 
Digital routine evaluations through online survey will also be deployed to
provide immediate feedback to immediately assess progress and correct
deviations will be adopted to facilitate accuracy and rapidity of the M&E
process. M&E Data will be immediately analysed and feedback provided to the
Census Project Management Team. 

22.5 Operationalisation of M&E Plans

Based on the objectives of the 2023 PHC, M&E o cers will monitor and
evaluate processes and functionaries from trainings to field implementation of
the projects where applicable and will specifically carry out such functions as
the following; 
● Daily evaluation of training workshops 
● Evaluation of field practice sessions
● Routine feedback on field experience as work progresses 
● Routine assessment on remedial measures taken on challenges reported 
● Suggestions and recommendations for improvement

22.6 Framework and Indicators

22.6.1 Resource and Results Framework

The M&E system for the 2023 PHC will be built on the Results Framework. The
Results Framework (RF) is an important tool that helps project managers to
identify and focus on key objectives within a complex project environment such
as 2023 PHC. The Results Framework focuses specifically on census inputs,
activities/processes, outputs, outcomes and impacts built on objectives and
thematic areas as shown in Figure 12.1.
Chain of e cient Monitoring Framework Linking Inputs to Impact

Figure 22.1: Schematic Diagram Showing a Schematic Representation of the
M&E Framework Proposed for the PHC

22.6.2. Essential Component of an Indicator

The following are some of the essential features of an indicator
a. Clearly stated title and definition
b. Stated purpose and rationale
c. Method of measurement for the indicator clearly defined, including
the description of the numerator, denominator and calculation, where
applicable
d. Data collection methodology and data collection tools for the indicator
data
e. MUST BE clearly stated (Census Methodology and Data Collection tools)
f. Data collection frequency clearly defined (Timeline)
g. Relevant sources of additional information on the indicator
h. Action focused, indicators should lead to action. If stakeholder cannot
imagine what to do with the data from an indicator, then it probably isn’t
a good indicator

Page | 241
i. It is important that stakeholders should agree that the indicator and the
data it will generate will make relevant and significant contributions
towards improving the Census process.
j. An indicator should be measurable. Not only must the data collection  
methodology be defined, it must also be feasible to collect the data.
