[Internal migrations: why investigate?].


 The problem of internal migration has become during the last 15 years of paramount importance for many countries. In Brazil, for example, in 1970 almost 1/3 of the population was defined as migrant; if this trend continues there will be 40 million migrants in 1980, and 60 millions in the year 2000. The phenomenon of migration, wherever it occurs, is always related to the economic system and to the social organization of some particular areas, as well as to the age and education of the migration population itself. Solutions to the problem must reflect a concentrated effort from the areas of social policy, urban planning and industrialization development. The formulation of internal migration policy belongs to the governments, as is the special distribution of national resources. The article also reviews recent studies on the problem, analyzes areas of possible government intervention, and supplies topics for relevant research which could prove useful and provide orientation to migration policy planners.
