MIGRATION






The greatest body of migrants travel long
distances and leave their native country.
Long distance movements are directed towards
rural farming areas.
People in urban areas migrate less than people
in urban areas.
Males migrate more over short distances
females migrate more over long distances.
Most migrants are 20-34 years of age.
People MAINLY move for cultural reasons.

Ravenstein’s Laws of Migration
1. Every migration flow generates a return or
counter-migration
2. The majority of migrants move a short distance
3. Migrants who do move longer distances tend to
choose large cities
4. Urban residents are less migratory than rural
folk
5. Families are less likely to make international
moves than young adults

Native Americans in the US
Soviet Union moving non-Russians to Central Asia
and Siberia

Voluntary Migration
Most migrations are voluntary – but they may
have been precipitated by bad things



Most for jobs/better life
Most people move for $ or €
Others because of war, environmental
problems
Immigration is causing great pressure on some
countries - Chad
More pop. growth due to immigration than
natural growth – U.S. is a good example
Remember – most population growth globally
is in Developing World

Migration – long term location
of an individual
 External and Internal
 Emigration – out migration
 Immigration – in migration


Distance Decay


More accurate perceptions of nearer places than far
away places.
Farther away from origin one gets, less likely a
behavior, activity, interaction will decay or cease.
Chain Migration – family member leaves,
sends word back, more come
 Step Migration – most migrations actually done
in segments – that is…
Farm  Village  Town  Suburb  City



Intervening Opportunity – immigrant has an
intended destination, but does not reach that
destination, instead settles somewhere along the
way
EXAMPLE – African Americans after WWI
migrate seeking work in Detroit, Chicago and
Cleveland only to find employment and stay in St.
Louis and Cincinnati
Detroit – Motown Records
 Tourists – visit a place that is cheaper; not like they
expected
 Snowbirds

Internal Migration – US E -W and N- S (MAP pages 73 and 85) –
what’s wrong on page 73?
How can professional sports show us the internal demographic
shifts of the last 40-75 years

Isn’t this an issue of Supply and Demand?
