Chain migration


• “Push” Factors are events or conditions that impel an individual to move from a location.

• “Pull” Factors are forces of attraction that influence migrants to move to a particular location.

• Most decisions to migrate are a combination of push and pull factors.

• Distance decay--most moves are to closer and more familiar locations

• Step migration--an eventual long-distance migration is undertaken in stages--farm to village to small town to city.


• Intervening opportunity--closer opportunities will reduce the attractiveness of interaction with more distant--even slightly better--alternatives.


Voluntary Migration

• Voluntary migration has an element of choice based on some percieved opportunity.

Forced Migration

• In forced migration, the element of choice is removed.

Slave Trade

Counter migration

• …or return migration…is the return of migrants to the regions from which they earlier emigrated.

• Every migration flow generates some counter-migration
