Key Issue 1: Why do people migrate?

2. Why Do People Migrate
Geographers document from Where people migrate and to where they migrate.
Also study reasons why people migrate.
Most people migrate in search of three objectives:
Economic Opportunity
Cultural Freedom
Environmental Comfort

3. Reasons for Migrating Migration – type of relocation diffusion.
Emigration – from a location.
Immigration – to a location.
Difference is net migration.
Push & Pull Factors – people decide to move based on these factors.
Most people migrate for economic reasons.

4. Economic Push and Pull Factors
Karrie wants you to do the “Push Factor!”
Push Factor – induces people to move out of their present location.
Pull Factor – induces people to move into a new location.
Relative attractiveness of a region can shift with economic change.

5. Cultural Push and Pull Factors
Forced International Migration – slavery and political instability.
20th century – political instability resulting from cultural diversity.
refugees – people who have been forced to migrate from their home country and cannot return for fear of persecution.

water – poses the most common environmental threat.

8. Intervening Obstacles

Today’s migrant – local diversity in government and politics.

9. Migration
Ravenstein’s theories – most migrants relocate a short distance and remain within the same country.
Long-distance migrants to other countries head for major center of economic activity.
International Migration – permanent movement from one country to another.
Internal Migration – permanent movement within the same country.

10. Migration
Interregional migration – movement from one region of a country to another.
Intraregional migration – movement within one region.

11. International Migration
Further divided into two types: forced and voluntary .
Zelinsky identified a migration transition, consists of changes in a society comparable to those in the demographic transition.
Stage 1: Unlikely to migrate permanently; has high daily or seasonal mobility in search of food (high birth and death rates and low NIR).
Stage 2: International and interregional migration from one country’s rural areas to its cities (NIR rises rapidly as a result of sharp decline in the CDR).
Stage 3 and 4: Destination of the international migrants leaving the Stage 2 countries in search of economic opportunities (CBR declines).
Internal migration within countries in Stages 3-4 of the DTM is intraregional, from cities to surrounding suburbs.

12. Characteristics of Migrants
Most long distance migrants are male.
Adult individuals rather than families with children.
Women now constitute about 55% of US immigration.
Ravenstein believed most long-distance migrants were young adults seeking work.
Mexico:
In the late 1980s males were about 85% of Mexican migrants to the US without proper documentation
Since 1990s women have accounted for about 50% of the undocumented immigrants coming from Mexico
