Abstract

Tendo como pano de fundo as rápidas transformações experimentadas pelapopulação brasileira ao longo do século XX, tais como a redução da imigraçãointernacional e a queda da mortalidade e da fecundidade, o trabalho analisa adinâmica populacional brasileira no passado recente e apresenta dois cenários deevolução futura para essa população.Os resultados apresentados consistem em projeções para os qüinqüênioscompreendidos entre 2000 e 2020, desagregados por sexo, grupos qüinqüenais deidade e situação de domicílio. O método utilizado para projetar a população foi o doscomponentes, que utiliza a projeção separadamente das três variáveis demográficas:fecundidade, mortalidade e movimentos migratórios do tipo rural-urbano. Foirealizada uma hipótese para cada um dos componentes demográficos, com exceção dafecundidade. Para essa variável, foram consideradas duas hipóteses, o que distingueos dois cenários.Segundo a hipótese 1, a população brasileira poderá atingir 217,4 milhões depessoas em 2020. A hipótese 2 prevê um contingente de 209,5 milhões de pessoas em2020. Nos dois cenários, as taxas de crescimento continuarão no seu processo dedecréscimo, podendo atingir valores próximos a 1,0% a.a. ou 0,7% a.a. no final doperíodo da projeção, respectivamente para as hipóteses 1 e 2.ABSTRACTThe paper analyses the marked changes experienced by the Brazilian populationthroughout the end of the XXth century. It also presents two sets of populationprojections for the quinquenium comprised between 2000 and 2020. They aredisaggregated by sex, age groups and place of residence (rural and urban).The projection was done using the component method. The start up is theprojection of each demographic component, fertility, mortality and rural-urbanmigration, separately. A single hypothesis was done for each component except forfertility. For it, two hypotheses were done which differentiated the two sets ofprojections.According to hypothesis 1, the Brazilian population would reach 217.4 millioninhabitants in 2020. The second hypothesis forecasts 209.5 million persons for thatyear. In both scenarios, population growth rates will continue to decline throughoutthe projection horizon. They would get values close to 1.0% a.a. or 0.7% a.a. in2015-2020 under respectively hypotheses 1 and 2.
