Lee's Migration Model shows migration between two locations, Location A and Location B. It depicts factors that can push people to leave Location A or pull people to Location B, as well as intervening obstacles between the locations that may hinder migration. The model illustrates the complex interplay of forces that influence people's movement between locations.
