Migration
Geographers study from where people
migrate and to where they migrate
They also study why they migrate
Migration- a permanent move to a new
location
Type of relocation diffusion (spread of a characteristic
through the bodily movement of people)
continued
Emigration- migration from a location
Immigration- migration to a location
Net migration- the difference b/w the # of
immigrants and the # of emigrants
If # of immigrants is higher, net migration is
positive—known as net in-migration
If # of emigrants is higher, net migration is
negative– net out-migration
Why Do People Migrate?
E. G. Ravenstein wrote 11 “laws” of
migration in 19th century
Serves as basis for modern migration study
“laws” concerned three areas of study
1. Why migrants move
2. The distance they typically move
3. The characteristics of migrants
Reasons for Migrating
Push factor- induces people to move out of
their current location
Pull factor- induces people to move into a
new location
Both factors usually play a role
3 major kinds of push and pull factors
1. Economic
2. Cultural
3. Environmental
Economic Push and Pull Factors
Most common reason for migrating
Move to places that seem to have opportunity
and out of places that have very little
US and Canada historically have had many
immigrants come for opportunity
Relative attractiveness of a region can shift
with economic change
Cultural Push and Pull Factors
Forced international migration is a cultural
push factor– ex.’s slavery and political
instability
Ethnic segregation and wars cause people to migrate
Refugees- people who have been forced to
migrate from their homes and cannot return for
fear of prosecution due to their race, religion,
nationality, or political opinion
continued
Refugees have no home unless another
country agrees to take them in
2 largest refugee groups are Palestinians and
Afghans
Palestinians left Israel after it was created in 1948
or after it expanded in 1967
2 largest groups of internal refugees are the
Sudanese (civil war) and the Columbians (drug
lords and guerrillas)
continued
Political conditions can also be a pull factor
Lure of freedom
Environmental Push and Pull
Factors
Pushed out of hazardous regions– pulled into
attractive ones
Attractive areas would include: mountains,
beach, and warm climates
Too little or too much water is a major push
factor
Drought and floodplains
An area subject to flooding during a specific number of
years
Intervening Obstacles
Def.- an environmental or cultural factor that
hinders migration
Historically, primarily environmental
Hard to travel across inhospitable environments
Ocean, mountains, desert
Modern transportation has made this much easier
Government and politics are obstacles today
Need passports to cross borders
Distance of Migration
Ravenstein said:
most migrants only move a short distance and
remain within the same country
Long-distance migrants to other countries head
major economic centers
Internal Migration
Def.- permanent movement within the same
country
Adheres to the idea of distance decay
The farther away a place is located, the less likely
people will migrate there
Explains why there are more internal migrants than
international migrants
Easier because there is less culture shock
continued
2 types of internal migration
1. Interregional migration- movement from one
region of a country to another
2. Intraregional migration- movement within one region
Historically, interregional migration has been
mostly rural to urban (but now environmentally
attractive rural areas are becoming popular)
Intraregional is usually within urban areas – city to
suburbs
International Migration
Def.- permanent movement from one country
to another
2 types
1. Voluntary migration- migrant has chosen to
move for economic improvement
2. Forced migration- migrant has been compelled
to move by cultural factors
Zelinsky’s Migration Transition
Def.- change in the migration pattern in a
society that results from industrialization, pop.
growth, and other social and economic
changes that also produce the demographic
transition
International migration is primarily a function of
stage 2 (people leave to go to stage 3 or 4
countries)
Internal migration is more important in stages 3
and 4 (cities to suburbs)
Characteristics of Migrants
Historically, males were more likely than
females to migrant internationally
Because men worked more than women and left to
find job opportunities
Since the 1990s, female migrants are on the rise
(about ½ in the US)
Most long distance migrants are young adults
seeking work –not children or elderly
continued
40% of US immigrants are b/w 25 and 39 (that
demographic is only 23% of entire US pop.)
Only 5% of immigrants are over 65
16% are under 15 – this number is on the rise
Global Migration Patterns
Asia, LA, and Africa have net-out migration
NA, Europe, and Oceania have net-in
migration
3 biggest migration flows are form Asia to
Europe, Asia to NA, LA to NA
Reflects the importance of migration from LDCs
to MDCs
People want the prospect of better jobs and higher pay
continued
US has more than 35 million people born in
other countries
More than half from LA
¼ from Asia
12% of US pop are immigrants
We have more immigrants than anybody
But, ¼ of Australian pop are immigrants
1/6 of Canadian
continued
½ the pop of the Middle East are immigrants
United Arab Emirates – 74%, Kuwait 68%
People from poorer areas of Middle East migrate to get
jobs in Oil exporting industry
US Immigration Patterns
70 million people have immigrated to the US
since 1820
The US has had 3 main eras of immigration
1. Colonial Immigration
2. 19th century European Immigration
3. Recent Immigration form LDCs
Colonial Immigration
2 sources: Europe and Africa
About 1 million Europeans migrated to the
American colonies before independence
90% from Great Britain
About 400,000 African slaves were forced to
migrate here during the same period
19 Century Migration
