The harmonised core module data are available in the combined dataset. The questions contained in the core modules of the two SASAS questionnaires for 2004 (demographics and core thematic issues) were asked of 7000 respondents, while the remaining rotating modules were asked of a half sample of approximately 3500 respondents each. The combined data set contains 5583 records and 255 variables. Core topics included in the questionnaires are: democracy, identity, public services and local government, health status, HIV/AIDS, health behavior, moral and religious issues, crime, voting, demographics and other classificatory variables. This version of the combined dataset should be used where analysis is to be performed at household level.
