Voluntary: when individuals choose to leave their homes.

15. Migration Theories: Ravenstein’s Model:
Most migrants proceed over a short distance.
Migration occurs in a series of stages: Rural to small town, small town to large town or city
Dispersal from large cities: as more migrants enter cities, rich move to near by villages (suburbs)
Long-distance migrants are more likely to move to large cities
Urban dwellers less likely to move than rural dwellers
Migration increases with advances in technology. This decreases distance decay due to space time compression.
