Some Structural Effects of Migration on Receiving and Sending Countries

Traditionally, the question of migration has been compartmentalized analytically between, on the one hand, the causes of international migration which in the main have been studied by economists and geographers and, on the other hand, the consequences of migration primarily on the receiving countries, which has mostly been an area of concern for sociologists, demographers and geographers who have looked into theories and processes of settlement/integration. The twain rarely met. As a consequence, for heuristic purposes a separation based on discipline, geographical areas and objects of study has taken place, an approach challenged recently by some scholars. This article brings together the threads of international migration in its causes and consequences affecting both sending and receiving countries as well as the migrants. The close interaction between causes and consequences is enhanced by the role of migrants themselves. Indeed, migrants are not only objects whose moves are deterministically conditioned by structural factors, they are social actors who formulate their own strategies and life projects within given settings and conflicts in their society of origin and society of reception, which they in turn contribute to modify.
