As migrações nas cidades médias de Minas Gerais e seus impactos no crescimento e na composição por sexo e idade da população no período 1980-2010

Abstract

The main objective of this paper is to investigate migration in the intermediate cities of Minas Gerais state in Brazil and its effects on growth and composition by age and sex of the population in the period 1980-2010. The data used came from the Demographic Censuses of 1980, 1991, 2000 and 2010 and from the question related to a previous place of residence at a fixed date over the last three censuses (disaggregated by sex and age). The results revealed a mixed picture regarding the impacts of migration on the volume and composition of the studied populations. Although most of the intermediate cities of Minas Gerais have shown positive and relatively high net migration in all analyzed periods, some striking exceptions were observed in the eastern portion of the state. While the effects of migration on the gender composition proved to be insignificant, effects on age structure were substantial, indicating a strong tendency for population gains from migration to slow population aging because of migrant age selectivity.
