Title in Portuguese: Funções de migração por idade e caracterização de migrantes das microrregiões de Goiás e Distrito Federal, 1975-1979 e 1986-1990(Dissertação de Mestrado)(M.A. Thesis)Since the 70’s, the Brazilian Middle-West Region has experienced an important modernization process in agricultural and industrial activities, which has led to an employment retraction and migration flows, especially from rural areas to the major metropolitan cities of the region. In this research the focus of analysis are the State of Goiás and the Federal District, which encompasses Brasília, the capital of Brazil. In order to understand the new population configuration, the region was divided into four sub-areas (micro-region of Goiânia, micro-region of Entorno de Brasília, the Federal District, and a group of 16 micro-regions of Goiás) and the patterns of migration, by age and sex, were estimated for the periods 1975-1979 and 1986-1991. In addition, differences between native and migrant population of each sub-area, according to the participation in the labor force, income, education and type of migration were investigated. The analysis was performed on the basis of the 1980 and 1991 Brazilian Census data.In the intra-state migration, the fluxes between the micro-region of Goiânia and the 16 other micro-regions of Goiás, and between the Federal District and the micro-region of Entorno de Brasília were the most important. In the inter-state migration, the flux from the states of Mato Grosso, Mato Grosso do Sul and the North region to the 16 micro-regions of Goiás, as well as the flux from Northeast, Southeast and South to the Federal District were significant. But there was a decline in the migration to the Federal District, between 1975-1979 and 1986-1991, while, in the same period, the migration to the Entorno of Brasília increased.The chance of the migrant population in the micro-region of Goiânia and in the Federal District to have worked in the last 12 months prior to census interview was lower than that of the native population. However, those who migrated from the Federal District to the micro-region of Entorno de Brasília had higher chance to have worked in the formal sector than those who did not migrate. Migrants who moved from the micro-region of Entorno de Brasília and the 16 other micro-regions of Goiás to the micro-region of Goiânia had lower wages than the non-migrant population. The lowest level of wages was recorded for the migrants to the 16 other micro-regions of Goiás. Migrants living in the Federal District had high level of education, while those migrants living in the micro-region of Entorno de Brasília had low level of education.In 1986-1990, the micro-regions of Goiânia and Entorno de Brasília, as well as the 16 other micro-regions of Goiás, presented a high percentage of returned migrants. In the same period, a major proportion of migrants to the micro-region of Entorno de Brasília had first moved from Southeast or from the Federal District to others regions. In addition, there was a considerable proportion of migrants with low income who had moved from Northeast to the Federal District and then to the micro-region of the Entorno de Brasília.Future research could focus other areas or regions of Brazil, and could also explore the same kind of analysis, on the basis of the incoming 2000 Brazilian Census, which requires the development of new techniques, as it did not collect information on the city of previous residence, but only on the state of residence.
