7Types of Migration
1
- International Migration
- Emigration is an indicator of economic and/or
social failures of a society. - Crossing of a national boundary.
- Easier to control and monitor.
- Laws to control / inhibit these movements.
- Between 2 million and 3 million people emigrate
each year. - Between 1965 and 2000, 175 million people have
migrated - 3 of the global population.
8Migration Policies and Global Migration Patterns
1
Period Policies Pattern
Before 1914 Open policies (showing up). Immigration as a source of labor and development. From developed (Europe) to developing countries (Americas, Africa, Australia). Immigration from Europe between 1880 and 1910 was exceeded 25 million.
1920s and 1930s Closed door linked with the economic depression. Deportation of immigrants. Limited migration.
After 1945 More open policies. Reconstruction in Europe (12 of labor force) and economic growth in America. Beginning to shift from developing to developed countries (12).
After 1973 Relatively open policies, but with more stringent requirements. Growth of refugees and illegal immigration. From developing to developed countries (88). 3 million illegal immigrants entering the US per year.

- Internal Migration
- Within one country.
- Crossing domestic jurisdictional boundaries.
- Movements between states or provinces.
- Little government control.
- Factors
- Employment-based.
- Retirement-based.
- Education-based.

20Types of Migration
1
- Local Migration
- No state boundaries are crossed.
- Buying a new house in the same town or city.
- Difficult to research since they are usually
missed in census data. - Based on change of income or lifestyle.
- Often very high levels of local migration.
- Americans change residence every 5 to 7 years.

21Types of Migration
1
- Voluntary migration
- The migrant makes the decision to move.
- Most migration is voluntary.
- Involuntary
- Forced migration in which the mover has no role
in the decision-making process. - Slavery
- About 11 million African slaves were brought to
the Americas between 1519 and 1867. - In 1860, there were close to 4 million slaves in
the United States. - Refugees.
- Military conscription.
- Children of migrants.
- Situations of divorce or separation.
22Types of Migration
1
Type Characteristics
International Crossing a boundary easier to control regulated difference in income 2-3 million per year.
National Between states or provinces little control employment opportunities education retirement.
Local Within a city/region change of income or lifestyle.
Voluntary The outcome of a choice.
Involuntary The outcome of a constraint.
23Selective Migration
2
- Context
- Many migrations are selective.
- Do not represent a cross section of the source
population. - Differences
- Age.
- Sex.
- Level of education.
- Age-specific migrations
- One age group is dominant in a particular
migration. - International migration tends to involve younger
people. - The dominant group is between 25 and 45.
- Studies and retirement are also age-specific
migrations.

- Sex-specific migrations
- Males
- Often dominant international migrations.
- Once established, try to bring in a wife.
- Females
- Often dominate rural to urban migrations.
- Find jobs as domestic help or in new factories.
- Send remittances back home.
- Filipino females 17-30 to Hong Kong and Japan.
- Mail-order bride
- 100,000 150,000 women a year advertise
themselves for marriage. - About 10,000 available on the Internet at any
time. - Mainly from Southeast Asia and Russia.
- Come from places in which jobs and educational
opportunities for women are scarce and wages are
low.
26Selective Migration
2
- Education-specific migrations
- May characterize some migrations (having or
lacking of). - High level of education attained by most
contemporary Asian immigrants to the USA and
Canada. - Educational differences
- 21 of all legal immigrants have at least 17
years of education. - 8 for native-born Americans.
- 20 of all immigrants do not have 9 years of
schooling. - Foreign students
- Often do not return to their home countries after
their education. - Often cannot utilize what they have learned.
- Since 1978 some 130,000 Chinese overseas students
have returned while some 250,000 have remained
abroad. - Most research-oriented graduate institutions have
around 40 foreign students.
27Selective Migration
2
- Immigration and jobs
- Related to the economic sector.
- High level
- Filling high skilled position in science,
technology and education. - Not enough highly trained personnel in the US.
- Result in recruiting abroad (see brain drain).
- Low level
- Filling low paid jobs (minimum wage) that most
people do not want (agriculture and low level
services). - Maintain low wages in low skilled jobs.
- Possibility of an informal economy.
28Brain Drain
3
- Definition
- Relates to educationally specific selective
migrations. - Some countries are losing the most educated
segment of their population. - Can be both a benefit for the receiving country
and a problem to the country of origin. - Receiving country
- Getting highly qualified labor contributing to
the economy right away. - Promotes economic growth in strategic sectors
science and technology. - Not having to pay education and health costs.
- 30 of Mexicans with a PhD are in the US.
29Brain Drain
3
- Country of origin
- Education and health costs not paid back.
- Losing potential leaders and talent
- Between 15 and 40 of a graduating class in
Canada will move to the US. - Long term impact on economic growth.
- Possibility of remittances.
- Many brain drain migrants have skills which they
cant use at home - The resources and technology may not be available
there. - The specific labor market is not big enough.
- May eventually come back with skills and
connections - Korea, Taiwan, China and India.

35Migration Theory
B
- 1. Push - Pull Theory
- What are the major push and pull factors
behind migration? - 2. Economic Approaches
- How can migration be explained from an economic
perspective? - 3. Behavioral Explanations to Migration
- How can migration be explained from a human
behavior perspective?
36Push - Pull Theory
1
- Context
- Migrations as the response of individual
decision-makers. - Negative or push factors in his current area of
residence - High unemployment and little opportunity.
- Great poverty.
- High crime.
- Repression or a recent disaster (e.g., drought or
earthquake). - Positive or pull factors in the potential
destination - High job availability and higher wages.
- More exciting lifestyle.
- Political freedom, greater safety and security,
etc.
37Push - Pull Theory
1
- Intervening obstacles
- Migration costs / transportation.
- Immigration laws and policies of the destination
country. - The problem of perception
- Assumes rational behavior on the part of the
migrant - Not necessarily true since a migrant cannot be
truly informed. - The key word is perception of the pull factors.
- Information is never complete.
- Decisions are made based upon perceptions of
reality at the destination relative to the known
reality at the source. - When the migrants information is highly
inaccurate, a return migration may be one
possible outcome.

41Economic Approaches
2
- Labor mobility
- The primary issue behind migration.
- Notably the case at the national level.
- Equilibrate the geographical differences in labor
supply and demand. - Accelerated with the globalization of the
economy. - Remittances
- Capital sent by workers working abroad to their
family / relatives at home. - 62 billion in 1999
- 16 billion each year goes out of Saudi Arabia as
remittances. - 2nd most important most important source of
income for Mexico (after oil and before tourism)
16.6 billion in 2004.

43Behavioral Explanations of Migration
3
- Life-cycle factors
- Migration linked to events in ones life.
- People in their 30s are the most mobile.
- Education, career, and family are being
established. - Later in life, flexibility decreases and inertia
increases. - Retirement often brings a major change.
- Large migrations of retired people have been
occurring in the direction of amenities-oriented
areas.

44Behavioral Explanations of Migration
3
- Migrants as risk-takers
- Why, among a population in the same environment
(the same push factors), some leave and some
stay? - Migrants tend to be greater risk-takers, more
motivated, more innovative and more adaptable. - Non-migrants tend to be more cautious and
conservative. - Can be used to explain the relative dynamism in
some societies, like the USA since the 1800s. - Summary
- No one theory of migration can adequately explain
this huge worldwide phenomenon. - Each brings a contribution to the understanding
of why people move.
45Refugees
C
- 1. Definition
- What is a refugee and how one qualifies for this
status? - 2. Contemporary Evolution
- How the refugee situation has evolved in time?
46Definition
1
- The United Nations definition
- The 1951 Convention Regarding the Status of
Refugees and the 1967 Protocol on the Status of
Refugees - ..... any person who, owing to a well-founded
fear of being persecuted for any reasons of race,
religion, nationality, member of a particular
social group or political opinion, is outside the
country of his nationality, and is unable or,
owing to such fear, is unwilling to avail himself
of the protection of that country. . - The problem lies in the definition of who is a
refugee. - There are no international agreements to protect
people who cross boundaries for their economic
survival.
47Definition
1
- Conditions to qualify for refugee status
- Political persecution must be demonstrated.
- An international boundary must be crossed
- Domestically displaced persons do not qualify.
- Protection by ones government is not seen an
alternative - The government may be the persecutor.
- Could be incapable of protecting its citizens
from persecution.
48Definition
1
- Environmental and economic refugees
- People who can no longer gain a secure livelihood
in their homelands because of what are primarily
environmental or economic factors of unusual
scope. - Sources
- Natural disaster.
- Human alterations to the environment climate
change. - Contamination (pollution) of the environment.
- Lack of development and opportunities.
- Render continued residence in that particular
location unsustainable. - Mozambique, February 2000
- Floods made 1 million people homeless.
- Destroyed agricultural land and cattle.
49Contemporary Evolution
2
- Origins
- The first recorded refugees were the Protestant
Huguenots who left France to avoid religious
persecution. - About 200,000 at the end of the 17th century.
- Went to England, Germany, the Netherlands,
Switzerland, and the English colonies in North
America. - Pre-WW II and during WW II
- Primarily political elites
- Fleeing repression from the new government, which
overthrew them. - Usually small in number and often had substantial
resources available to them. - War-driven refugees
- About 12 of the European population displaced.
- Usually could be expected to repatriate after the
war ended.
50Contemporary Evolution
2
- Post WW II
- Change in the patterns of refugee flows
- The majority of refugees are now coming from the
developing world. - De-colonization in Asia, Africa, and the
Caribbean - Political unrest in many newly independent
states. - Multi-ethnic nature of those states.
- The result of the drawing of colonial boundary
lines by Europeans. - The Cold War also increased political instability
in a number of countries. - Political instability in Latin America increased
due to the vast social inequalities existing in
that region. - New kind of refugee flow
- Large and of long (or permanent) duration.
51Contemporary Evolution
2
- Current issues
- Refugees are a controversial issue
- Especially in the developed world.
- Only a small share of the asylum seekers are
granted the refugee status. - Less than 20 for the European Union.
- Increasingly, refugees are no longer accepted.
- Economic refugees resorting to asylum as the only
way to get a legal status. - 1996 amendment to US immigration law
- Enforcing detention for all refugees entering the
United States. - INS can summarily deport those who arrive without
valid travel documents. - 4,000 detained on any given day.

56Context and Issues
1
Population growth (Natural increase or migration)
- What is urbanization?
- Urbanization is the agglomeration of population
in cities - Growth of the proportion of the population living
in cities. - Demographic process
- Urban population growth (natural increase or
migration). - Infrastructure process
- Expansion of urban infrastructures and land use.
- Economic process
- Creation of secondary, tertiary and quaternary
sectors. - Creates a society where values and lifestyles are
urban.
Urban expansion
57Context and Issues
1
- Causes of urbanization
- Historical
- Defense.
- Trade routes.
- Social
- Increased social interactions.
- Institutions representing a society (government,
religion education). - Economic
- Linked with agricultural surpluses.
- Increased economic opportunities.
- Access to labor.
- Specialization.
- Economies of scale and of agglomeration.
58Context and Issues
1
- The urban explosion
- Urban population growth is the most important
change in population geography. - About 50 of the global population, 3 billions,
lives in cities. - Almost all the population growth between 2000 and
2030 will occur in cities. - By 2050, 6.2 billion people will live in cities,
more than the current (2000) population. - Much of this growth will come in the worlds
poorest countries.

61Context and Issues
1
- Developed countries
- Developed countries are already urbanized.
- Passed through the rural - urban migration
process. - Concurrent with demographic transition and
industrialization. - Developing countries
- Going through a major phase of urbanization.
- Urbanization mainly occurs in developing
countries - Will account for 93 of the 2 billion increase in
the global urban population between 2000 and
2030. - Latin America and East Asia is farthest along.
- The rest of Asia is a little further behind.
- Africa is urbanizing more slowly than the other
world regions.

66Why People Move to Urban Areas?
2
- Context
- 50 million new urbanites each year.
- 1 million new urbanites each week.
- About 155,000 new urbanites each day.
- About 75,000 rural poor migrate to cities each
day. - Major changes in the developing world.
- Migration
- Makes a significant contribution to the growth of
urban areas. - Accounts for between 40 and 60 of annual urban
population growth in the developing world. - Huge rural-to-urban migration potential in areas
having a large rural population.
67Why People Move to Urban Areas?
2
- Push-Pull considerations
- Both are affecting rural-urban migrations.
- Pull of the cities may determine the
destination. - Migrants are pulled toward cities
- Prospect of jobs and higher incomes.
- Most early urbanization was the result of pull
considerations. - Pushed out of rural areas
- Push factors predominate as the motivation to
move. - Poverty, lack of land, declining agricultural
work, war, and famine. - Play more importance today than push
considerations.

71Why People Move to Urban Areas?
2
- Urbanization and economic survival
- Decision to move to an urban area
- Part of a complex survival strategy.
- Families minimize risk by placing members in
different labor markets. - Largest labor market maximizing the chances of
employment and survival. - Cities are the largest labor markets.
- Favelas (squatter settlements) of Rio de Janeiro
- Cannot be understood without reference to the
latifundia land system in rural Brazil. - Characterized by large landholdings owned by a
limited elite. - Peasants as contract labor with no ownership.
72Megacities and Urban Regions
3
- Concentration
- An increasing share of the global population
lives in megacities - Megacities (over one million).

77Shantytowns
4
- Context
- Many of the new urban dwellers, particularly
women and their children, are among the poorest
people in the world. - Difficulty to access housing
- Economic costs.
- Availability.
- 100 million people are homeless.
- 928 million live in precarious housing conditions
(slums). - Shantytowns informal habitat or squatter
housing - Favelas (Brazil).
- Pueblos jovenes (Young towns).
- Asentamiento irregulares (Irregular
settlements). - Villas miserias (Miserable villages, Argentina).
- Jughi Jopri (India).
78Shantytowns
4
- Definition
- Dwellings are built by the current or original
occupant - Rudimentary construction materials.
- Did not receive a construction permit.
- Do not follow norms in terms of housing and
sanitation. - Inhabitants have no legal title to the land
- Most are located in areas being declared
inhabitable. - Own by the municipality.
- Abandoned private land.
- Exploiting a legal vacuum of land ownership.
- Lack of urban services
- Generally not serviced by public utilities such
as tap water, electricity, roads, public
transportation and sewage.
79Shantytowns
4
- Setting
- Shantytowns are constructed over the least
desirable land. - Put the population at risk.
- Caracas, Venezuela, 1999
- Mudslides killed 50,000 inhabitants.
- Created 400,000 homeless.
- 500,000 of the 6 million inhabitants were
considered at high risk. - Bhopal, India, 1984

4
- Habitat
- Informal settlements
- Perhaps the most visible sign of widespread
poverty. - About 25 of the surface of cities in developing
countries is covered by shantytowns. - 30-60 of the urban population.
- Emerged in all Third World cities
- Following the demographic explosion.
- Now the norm more than the exception.
- Incapacity of private and public instances
- Provide low price housing for the majority of the
population. - The State more concerned about providing housing
for its public servants and its middle class. - Housing crisis that could not be solved.
81Shantytowns
4
- Growth process
- People expelled from gentrification in downtown
areas. - Inflow of people expelled from poverty in rural
areas. - In several cases, rightful owners of land have
divided it in small lots and sold it in order to
have a higher profit. - In some instances, land was illegally sold to
dwellers being framed. - Is there any hope?
- Housing has always been a priority for
investment. - As the population of Third World cities gets
higher incomes, the priority will be improving
their housing conditions. - On the long run, shantytowns are likely to
disappear (or at least become less significant).
