title: Populations on the move.
abstract: "This article sets out the broad nature of population movements and changes in distribution which are taking place in the major continental areas of the Third World, while making comparisons and contrasts.  It outlines the differing approaches to these movements, and the interpretations of varying ideological and disciplinary points of view.  It describes contemporary practical problems and indicates possible future developments." The primary focus is on internal migration.
