Redes sociais e conexões prováveis entre migrações: internas e emigração internacional de brasileiros

This article shows evidences of the probable connections between the internal and international migration among the micro-regions of Governador Valadares and Ipatinga and the others micro-regions of Brazil, based on the social network analysis.

Mobilidade espacial dos imigrantes estrangeiros no Brasil - 1991/2010

Na formacao do territorio brasileiro, os fluxos migratorios internacionais e internos desempenharam papel central. Se as correntes de imigrantes oriundas da Africa e da Europa fomentaram as atividades economicas do passado; as novas ondas migratorias, a contar de meados do seculo XX, conformaram a dinâmica socioespacial brasileira mais recente. Ao lado de tradicionais destinos como o Japao e Estados Unidos, novos movimentos populacionais internos a America do Sul ganharam importância, incluindo os fluxos de entrada no territorio brasileiro. Em face dessa dinâmica migratoria, constitui objetivo principal deste trabalho o levantamento das diferentes nacionalidades dos imigrantes estrangeiros residentes no Brasil e a analise das diferencas na mobilidade espacial interna desses mesmos estrangeiros. De acordo com dados extraidos dos censos demograficos de 1991, 2000 e 2010, nota-se uma expressiva expansao do numero de estrangeiros naturais dos paises latino-americanos em terras brasileiras, em especial dos vizinhos do cone sul, e um significativo nivel de mobilidade espacial interna dos paraguaios e dos bolivianos.

Of a method for estimating the average population size of personal networks and the size of hard-to-count populations

The method known as Network Scale-Up (NSU) – used for expanding social networks – is used to estimate hard-to-count populations, based on the idea that human populations are organized in a complex web of social interactions, to which all individuals, regardless of specific personal attributes, are connected. If we know the pattern of personal networks associated with certain individual attributes, we can estimate “parcels” of the population that have these same attributes. International migrants, especially those who are undocumented, fit into this type of subpopulation whose size is unknown because of the difficulty or even impossibility of measuring it directly. This article aims at describing the Network Scale-Up method and the methodological procedures necessary to estimate the number of international and returned migrants in a hypothetical, medium-sized, Brazilian city.
