POPULATION AND RESOURCES
Social,economic and political effects of migration.
Construct two mindmaps to explain the social,economic and political effects of migration. One mindmap should be for the area of origin and one should be for the area of destination.
Begin each one on a sheet of A4 or A3 paper with a central title. Then, from the central title radiate three new arms, one each for social, economic and political effects. Then, for each of these have two further arms, one for positive effects and one for negative effects.
