Chapter 3
What Is Migration? • Movement
– Cyclic movement: Movement away from home for a short period
•Commuting
•Seasonal movement
•Nomadism
– Periodic movement: Movement away from home for a longer period.
•Migrant labor
•Transhumance
•Military service
• Migration: A change in residence intended to be permanent
International migration: Movement across country borders (implying a degree of
permanence)
Internal migration: Movement within a single country’s borders (implying a
degree of permanence)
Why Do People Migrate?
• Forced migration: Movers have no choice
but to relocate
Kinds of Voluntary Migration
• Step migration: When a migrant follows a series of stages, or steps, toward a final destination.
Intervening opportunity : At one of the steps along
the path, pull factors encourage the migrant to settle there
• Chain migration: Further migration to a place where friends or relatives have already settled
Voluntary Migration
• Migrants weigh push
and pull factors to
decide
– Whether to move
– Where to go
• Distance decay: Many
migrants settle closer
to their old home than
they originally
contemplate
Ravenstein’s Laws (Gravity Model)
1. Every migration flow generates a return or countermigration.
2. The majority of migrations move a short distance.
3. Migrants who move longer distances tend to choose big-city destinations.
4. Urban residents are less migratory than inhabitants of rural areas.
5. Families are less likely to make international moves than young adults.
