ABSTRACT
There has been much discussion about migration in recent years from students of population in various disciplines including geography. Migration takes place from an area of origin (departure) to one of destination (arrival) and a group of migrants with a common origin and destination is called a migration stream. Migration takes place when an individual decides that it is preferable to move rather than to stay and where the difficulties of moving seem to be more than offset by the expected rewards. The variety of moves classified as migration calls for a typology to attempt to introduce some order to the apparent chaos. Recently, Lee has returned to the same theme and restated Ravenstein’s laws in a series of hypotheses about the volume of migration under varying conditions, the development of stream and counterstream and the characteristics of migrants. Migration can be studied at different spatial scales and the analysis of flows depends on the level of generalization.
