Este trabalho busca contextualizar o tema do espraiamento na evolução urbana da Região Metropolitana de São Paulo. Definimos espraiamento urbano como o crescimento urbano que é desconcentrado, não denso e que deixa vazios urbanos dentro da mancha urbana. Analisamos os mapas da área urbanizada entre os anos de 1962 e 2002, a evolução das densidades populacional e de empregos e a evolução dos gradientes de densidade. Propomos a construção de um índice de espraiamento. Sua evolução temporal é analisada através da metodologia de cadeias de Markov, enquanto seus determinantes são buscados em análise econométrica. Os resultados indicam que houve espraiamento no período mais recente analisado e que esse fenômeno se dá a partir da ocupação das periferias por população de baixa renda. This work deals with the issue of urban sprawl within the context of the São Paulo Metropolitan Area. We define urban sprawl as leapfrogging, not concentrated and not dense urban growth. We analyze urban area maps between the year of 1962 and 2002, the evolution of population and jobs density and the evolution of density gradients. We propose the construction of a sprawl index. Its evolution is analyzed using Markov chain models, while we search its determinants using econometric tools. Results point out that there was urban sprawl in the most recent period of time. The determinants show the link between this phenomenon and the occupation of suburbs by low income families.
