Voluntary Migration
Human migration flows in which the movers respond to perceived opportunity, not force. Migrants weigh options and choices before moving.
Ravenstein’s Laws of Migration
- Every migration flow generates a return or counter-migration.
- The majority of migrants move a short distance
- Migrants who move longer distances tend to choose big-city destinations.
- Urban residents are less migratory than inhabitants of rural areas.
- Families are less likely to make international moves than young adults.
Gravity Model
An inverse relationship between the volume of migration and the distance between source and destination: the number of migrants to a destination declines as the distance they must travel increases.
Push vs Pull Factors
Push Factors: Are the conditions and perceptions that help a migrant decide to leave a place.
Pull Factors: Are the circumstances that effectively attract the migrant to certain locales from other places, the decision of where to go.
Intervening Opportunity
When a migrant finds what they are looking for along the way and settle in a destination that was not their original one.
Chain Migration
Flows along kinship links through letters, phone calls, or other forms of communication that create a positive perception of the destination for families and friends.
