D. Trainings and Fieldwork for the Conduct of the POPCEN 2015 D-1
INTRODUCTION
Like the previous censuses conducted in the country, the POPCEN 2015 was
designed to take an inventory of the population of the Philippines and to collect
information about its characteristics.
The authority and mandate of the PSA to conduct the POPCEN 2015 emanates
from Republic Act (RA) No. 10625 and Executive Order No. 352.
RA No. 10625, also known as the Philippine Statistical Act of 2013, which was
approved on 12 September 2013, states that “the PSA shall be primarily responsible for
all national censuses and surveys, sectoral statistics, consolidation of administrative
recording system, and compilation of national accounts.” Specifically, Section 6(b) of
this Act mandates the PSA “to prepare and conduct periodic censuses on population,
housing, agriculture, fisheries, business, industry, and other sectors of the economy”.
Executive Order No. 352 – Designation of Statistical Activities That Will Generate
Critical Data for Decision-Making of the Government and the Private Sector, stipulates
the conduct of a mid-decade census primarily to update the population count in all
barangays nationwide.
Section 9 of RA No. 10625 states that one of the functions of the PSA Board is to
prescribe appropriate frameworks for the improvement of statistical coordination and
establish mechanisms for statistical coordination at the regional and LGU levels. With
this mandated function and being the highest policy making body on statistical matters,
the PSA Board was designated as the National Census Coordinating Board (NCCB) for
the POPCEN 2015.
Explanatory Text 2015 Census of Population
The NCCB was chaired by the PSA Board Chairperson, who is the Secretary for
Socioeconomic Planning and Director, National Economic and Development Authority
(NEDA). The Secretary of the Department of Budget and Management or his/her duly
authorized Undersecretary served as the NCCB Vice-Chairperson. The members of the
Board were the National Statistician (NS) of the PSA, who served as the Executive
Officer (EO) of the NCCB; Executive Director of the Philippine Statistical Research and
Training Institute; one representative each from the executive departments; Bangko
Sentral ng Pilipinas; Commission on Higher Education; Technical Education and Skills
Development Authority; Governance Commission for Government-Owned and -
Controlled Corporations; Philippine Statistical Association, Incorporated; Union of Local
Authorities of the Philippines; and the private sector.
The local census coordinating boards were composed of the Regional Census
Coordinating Board (RCCB), Provincial Census Coordinating Board (PCCB), and
City/Municipal Census Coordinating Board (C/MCCB). The PSA Regional Director (RD)
was responsible for organizing the RCCB. The RD oversaw the creation of the PCCB by
the Provincial Statistics Officer (PSO) in all the provinces under his/her jurisdiction. The
PSO, on the other hand, oversaw the creation of the C/MCCB by the Provincial
Statistical Office (PO) statistician/staff in all the cities/municipalities under his/her
jurisdiction. In provincial capitals where there are no PO statistician/staff designated to
create the local CCB, the PSO was responsible for the formation of the C/MCCB.
Aside from the national and local CCBs, the PSA likewise coordinated with other
government agencies such as the Philippine Information Agency, National Commission
on Indigenous Peoples, National Commission on Muslim Filipinos, and National
Commission on Disability Affairs. Coordination was also made with nongovernment
organizations (NGOs), religious groups and civic organizations (both at the national and
local levels); homeowners, village associations, and building administrators; and
indigenous cultural communities/indigenous peoples (ICCs/IPs).
The operational definitions and concepts adopted in the POPCEN 2015 have
also been used in the past censuses of population. The use of the same operational
definitions of terms and concepts in population censuses ensures comparability of
census results. The POPCEN 2015 enumerators were instructed to adhere strictly to
these operational definitions.
Barangay
A barangay is the smallest political unit in the country. Generally, one enumerator
(EN) is assigned to enumerate one barangay.
The official list of barangays of the Department of the Interior and Local
Government (DILG) in the Philippine Standard Geographic Code as of December 2015
was used for the POPCEN 2015.
All persons were enumerated in their usual place of residence, which refers to
the geographic place (street, barangay, city/municipality or province) where the person
usually resides. As a rule, a person’s usual place of residence is the place where that
person sleeps most of the time. Hence, it may be the same as or different from the
place where he/she was found at the time of the census.
Household
In most cases, a household consists of persons who are related by kinship ties,
such as parents and their children. In some instances, several generations of familial
ties are represented in one household while, still in others, even more distant relatives
are included as members of the household.
A person who shares a housing unit with a household but separately cooks
his/her meals or consumes his/her food elsewhere is not considered a member of the
household he/she shares the housing unit with. This person should be listed as a
separate (one member) household.
Household Population
Institutional Population
Institutional population comprises of persons who are found living in ILQs. They
may have their own families or households elsewhere but at the time of the census,
they are committed or confined in institutions; or they live in ILQs and are usually
subject to a common authority or management, or are bound by either a common public
objective or a common personal interest.
Household Membership
In determining the household membership, the basic criterion was the usual
place of residence or the place where the person usually resided. This may be the same
or different from the place where a person was found at the time of the census. As a
rule, it was the place where a person usually sleeps.
As in the past population and housing censuses, ENs of POPCEN 2015 were
provided with guidelines on whom to list as members of a household and ILQ. This
helped ensure uniformity in determining household membership, institutional population,
and in identifying persons to be included in the enumeration or excluded from it. Further,
this helped ensure that there was no omission or duplication in the enumeration of
persons and households during census-taking. The following guidelines were used in
determining household membership and institutional population:
1. Those who were present at the time of visit and whose usual place of
residence was the housing unit where the household lived;
2. Family members who were overseas workers and who were away at the
time of the census and were expected to be back within five years from
the date of last departure.
These included household members who may or may not have had a
specific work contract or had been presently at home on vacation but had
an existing overseas employment to return to. Undocumented overseas
workers or the so-called TNT (Tago Nang Tago) were still considered as
members of the household for as long as they had been away for not
more than five years. Immigrants, however, were excluded from the
census.
3. Those whose usual place of residence was the place where the household
lived but were temporarily away at the time of the census for any of the
following reasons:
7. Persons temporarily staying with the household who had no usual place of
residence or who were not certain to be enumerated elsewhere.
3. Hotel residents who stayed in the hotel for more than six months at the
time of the census;
5. Patients in hospitals who were confined for more than six months;
7. Wards in orphanages, homes for the aged, and other welfare institutions;
Included in the enumeration were those who were alive as of the POPCEN 2015
reference date, that was, 12:01 a.m. of 1 August 2015 were enumerated.
Specifically, these were the following:
5. Civilian citizens of foreign countries who had their usual residence in the
Philippines, or foreign visitors who had stayed or were expected to stay for
at least a year from the date of their arrival in this country.
Excluded from the enumeration were the following persons, although they
happened to be within the territorial jurisdiction of the Philippines at the time of
the census enumeration:
Method of Enumeration
The gathering of population and housing data was performed by census ENs
through house to house visits and interview of a responsible member of each household.
Self-Administered Questionnaires (SAQs) and/or Electronic Questionnaires (E-
Questionnaires) were provided to households living in special areas, such as high-rise
buildings/condominiums, exclusive subdivisions/villages, and townhouses, and
institutions where personal interview was not possible. A complete listing of buildings
which contain living quarters, including the vacant ones, as well as housing units and
ILQs was also done.

FIDEL V. RAMOS
President of the Philippines
The 2015 Census of Population (POPCEN 2015) is designed primarily to take an inventory
of the population in the Philippines and collect information about their characteristics. All information
about the population and living quarters were collected as of 12:01 AM of 1 August 2015, the census
reference date and time.
The Philippine Statistics Authority (PSA) is the agency mandated by law to conduct the
POPCEN 2015. Republic Act (RA) No. 10625 and Executive Order (EO) No. 352 are the legal
bases for the conduct of this census. RA No. 10625 mandates the PSA to conduct national
censuses and surveys, while EO No. 352 requires the conduct of a mid-decade census. Section
25 of RA No. 10625 provides that all respondents are obliged to give truthful and complete
answers during the censuses and surveys conducted by the PSA while Section 26 stipulates the
confidentiality of information provided by respondents to the PSA in censuses and surveys.
An EN was assigned to enumerate one enumeration area (EA), which had about 400
households. To ensure quality data collection during the census enumeration, a ratio of one TS
for every four ENs and one CAS for every five TSs was implemented, in general.
To prepare the hired census personnel for enumeration work, four levels of training were
conducted. The first level or the task force training for enumeration was conducted within Metro
Manila on 29 June to 4 July 2015. The said training was participated in by selected personnel of
the PSA central, regional, and provincial offices, who, in turn acted as trainers in the succeeding
levels of training. The second level training was conducted within the region for selected PSA
provincial and regional office staff who, in turn, served as trainers in the third and fourth level
training. The third level training, which was conducted within the province was participated in by
selected provincial office personnel and pre-selected hired CASs. The ENs and TSs were
trained during the fourth level training, which was conducted within the city and municipality with
available training center. A standard training program covering the concepts, definitions,
procedures, as well as duties and responsibilities of ENs and supervisors was used.
Census-taking involved going around the whole enumeration area to do the required
census procedures, as follows:
1. Courtesy Call. As a matter of protocol, the census personnel made a courtesy call to
the Punong Barangay. The ENs informed the official that the census would be
undertaken in the barangay and that they would go around the entire area to ask
questions from the residents.
2. Mapping and Canvassing. The ENs went around the entire EA to familiarize
themselves with the place, checked the barangay or EA boundaries and landmarks,
and reflected these on the barangay/EA map.
3. Listing. The ENs listed buildings with living quarters, housing units, households and
number of household members, and institutional living quarters (ILQs) and number of
persons staying in ILQs in CP Form 1 or the Listing Booklet. Structures which were
occupied or used as living quarters by households, even though these were not
intended for human habitation were also listed. During the listing, the names of the
household heads and their addresses, and the names and addresses of ILQs were
recorded.
4. Interview and Recording of Answers. For every household or ILQ listed, the ENs
administered a questionnaire, that is, CP Form 2 for a household or CP Form 4 for an
ILQ. The Punong Barangay or any barangay official was also interviewed by the ENs
or their TS using CP Form 5 (Barangay Questionnaire).
5. Plotting. The ENs plotted the building with its assigned serial number on the EA
map. Standard cartographic symbols were used in plotting the buildings of the
households and ILQs.
Progress monitoring reports were utilized to track the progress of census and field
operations and evaluate the completeness of census coverage in each barangay/EA while the
enumeration was still ongoing. The provincial, regional, and central offices of the PSA
monitored the progress of enumeration through the Progress Monitoring System (PMS). The
PMS generated reports on the number of households, ILQs, and persons enumerated based on
the information sent by the area supervisors through short messaging system (SMS) or text
messaging.
The POPCEN 2015 adopted the following technologies to make the census operations
efficient:
1. GPS technology for mapping. For this census round, GPS (Global Positioning
System) technology was used for mapping selected barangays in all regions. This
activity provided the ENs with more accurate maps with exact boundary information.
The use of GPS technology will be continued by the PSA as part of its rolling
program for mapping activities.
2. SMS technology for progress monitoring. The PSA made use of the SMS technology
in monitoring the progress of census enumeration nationwide. Started in the 2007
census, the enhanced version of the PMS was adopted for this census round. The
Philippines is the first country in Asia and the Pacific to use the SMS technology in
progress monitoring.
3. OMR technology for data processing. The use of Optical Mark Reader (OMR)
technology in the Philippine census started in the 2000 Census of Population and
Housing (2000 CPH). The Philippines is among the first few countries to have
successfully used this technology. The use of OMR shortened the data entry phase
because only selected items with codes corresponding to write-in entries were
encoded. Data encoding using KFI was done instead of keying from the
questionnaires.
5. MIS for quick monitoring of selected POPCEN 2015 activities. The Management
Information System (MIS) is a web-based application system that served as a sound
board for both the PSA CO and Field Office (FO) staff. It facilitated the monitoring of
status of delivery of census questionnaires and supplies, reporting of accidents,
injuries, and deaths, among others.
The PSA implemented various strategies to enumerate areas which were hard to reach,
remote, upland or mountainous, under military control or with peace and order problem, Chinese
communities or exclusive villages with low response rate for reasons of security or other
concerns, and areas with boundary disputes. These strategies included the recruitment of ENs
who were from the area; coordination with various government agencies and local government
units for mobility; coordination with local officials; and coordination with homeowners’
associations in exclusive villages, high-rise condominiums, and in communities inhabited by
many foreign nationals and indigenous peoples.
Progress monitoring reports were utilized to track the progress of census field operations
and evaluate the completeness of census coverage in every barangay/enumeration area (EA).
The provincial, regional, and central offices of the Philippine Statistics Authority (PSA) monitored
the progress of census enumeration through the Progress Monitoring System (PMS).
Information on a completely enumerated area was sent to the Central Office (CO) through Short
Messaging Service (SMS) using information from CP Form 1 (Listing Booklet). The Field Offices
(FOs) and CO monitored the progress of enumeration through the use of PM reports generated
from the PMS.
The Regional Statistical Services Office (RSSO) was responsible for the evaluation of the
2015 Census of Population (POPCEN 2015) counts for the provinces in the region while the
Provincial Statistical Office (PO) was responsible for the evaluation of population counts in the
cities and municipalities in the province. The computerized reporting through the PMS facilitated
the evaluation of population counts at the RSSO and PO. The PMS generated various reports,
which include the progress of enumeration by EA with total number of households and total
population (PM Report 2). This report showed the EAs, which were completely enumerated as
of the date the report was generated. It also showed the percentage of EAs in a barangay,
city/municipality or province that has completed the census taking. This report was used to
evaluate the acceptability of the reported counts for the following indicators, computed at the
barangay level in comparison with the results of the 2010 Census of Population and Housing:
The FOs investigated areas with demographically implausible growth rates and
questionable values in any of the above cited indicators.
Parallel monitoring and evaluation of population counts were done at the CO, particularly
at the Population and Housing Census Division (PHCD). The information used by the PHCD for
evaluation were:
a. POPCEN 2015 counts at the barangay level generated through the PMS;
b. POPCEN 2015 counts at the barangay level from the Enumeration Area Reference
File (EARF) filled up with population counts by the POs after matching and
completeness checking of census questionnaires during the manual processing;
c. POPCEN 2015 counts at the barangay level generated from the Quick Count;
d. average annual population growth rates for the provinces and cities/municipalities for
the periods 1995-2000, 2000-2007, 1995-2007, 2000-2010, 2007-2010, 2010-2015
and for all geographic levels, that is, including barangay level, for the period 2010-
2015;
e. sex ratio for the provinces and cities/municipalities for the year 2010, and for all
geographic levels for the year 2015;
f. average household size for all geographic levels for the years 2000, 2007, 2010 and
2015;
g. percent change of population between census years 2000 and 2007, 2000 and 2010,
2007 and 2010, 2007 and 2015, and 2010 and 2015 for all geographic levels; and
h. difference in the total population, household population, and number of households
between census years 2000 and 2007, 2000 and 2010, 2007 and 2010, 2007 and
2015, 2010 and 2015 for all geographic levels.
Below are the other sources of information used as inputs for the extrapolation of
population counts for 2015. The results of extrapolation were compared with the population
counts from 2010 CPH, using the balancing equation assumption:
a. vital registration data on annual births and deaths and estimates of levels of
registration based on POPCEN 2007 and 2010 Census of Population and Housing
(2010 CPH), for the provinces and cities/municipalities; and
b. number of housing units based on satellite images, for selected provinces and
cities/municipalities.
