3. Review: Internal Migration- permanent move within the same country
Interregional: movement from one region to another. i.e. rural to urban.
Intraregional: movement within a region. i.e. central city to a newer suburban center
International Migration-
Voluntary international migration could be motivated by perceived economic or quality of life improvement.
Forced international migration is motivated by political or environmental factors.
Internal Migration-
Interregional – movement from one region to another. i.e. rural to urban.
Intraregional- movement within a region. i.e. central city to a newer suburban center.

4. Where Do People Migrate within a Country?
Interregional Migration
Perceived economic betterment typically compels individuals to make interregional migrations.
Historically- enticement of abundant available land on the American Frontier.
Presently- most jobs, especially in services, are clustered in urban areas.
Westward expansion contributed to a shift in the center of population.
“Center of population gravity”
Center of population gravity refers to the country’s center of population, as calculated by the U.S. Census Bureau. Conceptually, if the United States were a flat plane placed on top of a pin, and each individual weighed the same, the population center would be the point where the population distribution causes the flat plane to balance on the pin.

5. CHANGING CENTER OF U.S. POPULATION The population center is the average location of everyone in the country, the “center of population gravity.” If the United States were a flat plane placed on top of a pin, and each individual weighed the same, the population center would be the point where the population distribution causes the flat plane to balance on the head of a pin.

7. Migration Between Regions of a Country (Interregional):
Migration Between Regions Within the U.S.
Recent Growth of the South
1920s: population center moved southward
People migrate south for job opportunities and environmental reasons (“sunbelt”)
Interregional antagonism: feelings that southern states are stealing industries
African Americans have migrated from the South to take jobs in large cities of Northeast, Midwest, and West

8. Intraregional migration:
The movement within one region (New York to New Jersey, for example). Typically this is from rural to urban areas in search of jobs (Nassau County to Manhattan)

12. Migration between Regions in Large Countries
World’s five largest countries in land area are Russia, Canada, China, the U.S., and Brazil.
Russia: Interregional migration was encouraged eastward and northward by the government’s decision to locate new factories and to offer economic incentives away from existing population concentrations.
POPULATION DISTRIBUTION: RUSSIA Russia’s population is clustered in the west of the country, nearest to Europe.

13. Migration between Regions in Large Countries
Canada: Shares a similar east to west interregional migration pattern with the U.S. Three westernmost provinces are destinations for interregional migrants.
China: Nearly 100 million people have emigrated from rural interior to large urban areas along east coast where manufacturing is prevalent.
Brazil: Government moved its capital from Rio De Janeiro to Brasília (600 miles from Atlantic Coast) to encourage migration of Atlantic coast residents to move to the interior.

15. Migration Within One Region (Intraregional):
Migration from Rural to Urban Areas
Percentage of people in U.S. living in urban areas has increased from 5% in 1800 to 50% in 1920 to 75% today
Worldwide, more than 20 million people each year migrate from rural to urban areas
Pushed from declining opportunities in agriculture and pulled toward prospect of work in factories/service industries

16. Migration Within One Regions (Intraregional):
Migration from Urban to Suburban
In MDCs, most intraregional migration is from cities to suburbs
Pulled by suburban lifestyle (houses, yards, garages, parking, schools, safety, accessibility to city through cars and trains)

17. Counter urbanization:
Net migration from cities and suburbs to smaller towns and rural communities. This occurred during the late 20th century in the more developed countries of North America and Western Europe.
People make this move primarily for lifestyle reasons. Exchanging the frantic city life for a more laid back and isolated lifestyle.
This trend has mostly stopped in the U.S.

20. The Chinese migrated for economic opportunities as traders.
British relocated many Asian during the colonial period as did the Dutch.
The Chinese migrated for economic opportunities as traders.
Today they make up 14% in Thailand
32% in Malaysia
76% in Singapore
3% in Indonesia, but that is a large number out of 200 million.

22. International Migration –
Movement across country borders (implying a degree of permanence).

24. Trans-Siberian Railway increased migration to the east.

25. Intraregional Migrations in LDCs:
Populations in the less developed world are rushing to cities in search of work and income.
Urbanization
migration from rural areas
lack of jobs in countryside
lack of services in cities
Tokyo, Los Angeles, and New York only MDC cities on top 10 list

Mumbai, India
