    Geographical stratification by socio-economic status: methodology from a household survey with elderly people in S. Paulo, Brazil
    (Faculdade de Saúde Pública da Universidade de São Paulo, 1989-12-01) Ramos, Luiz Roberto [UNIFESP]; Goihman, Samuel [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Secretaria de Estado da Saúde de São Paulo Cooordenação do Programa de Saúde do Idoso; Secretaria de Estado da Saúde de São Paulo Centro de Informação em Saúde
    Considering that in most developing countries there are still no comprehensive lists of addresses for a given geographical area, there has always been a problem in drawing samples from the community, ensuring randomisation in the selection of the subjects. This article discusses the geographical stratification by socio-economic status used to draw a multistage random sample from a community-based elderly population living in a city like S. Paulo - Brazil. Particular attention is given to the fact that the proportion of elderly people in the total population of a certain area appeared to be a good discriminatory variable for such stratification. The validity of the stratification method is analysed in the light of the socio-economic results obtained in the survey.
