ABSTRACT
The movement of population from one location to another is a basic dynamic of an urban system. Population mobility alters the relative distribution of individuals and households both between regions of a country and within areas of cities and towns and thus changes the nature of demand for housing, public and private finances and other services. As well, it acts to fulfil individual expectations and aspirations and to abet or frustrate goals in population distribution and resource provision. The study of population movements thus has a utility far beyond a mere description of where people live at a particular point in time, or the patterns of movement in space.
