Abstract
The South African Integrated Family Survey was undertaken in the second half of 1999 in the Langeberg district of the Western Cape province of South Africa. This area comprises the three magisterial districts of Mossel Bay, Heidelberg, and Riversdal which, at the time of the 1996 census, had a population of just under 97 000 persons of whom more than three-quarters (78%) lived in urban areas. The remaining 22% of the population lived in 'non-urban' areas, mainly commercial farms.

Sampling
Weighting
Weights are the inverse of the probability of selection of the household (which were calculated when the sample EAs were drawn) times the inverse of the response rate (which may be interpreted as an inverse probability of selection under the assumption that observations are missing at random within EA's). This product summed across the 294 households to an arbitrary number approximately equal to the total number of households in the Langeberg district. The weights were rescaled to sum across completed households to the sample size, 294, by dividing each weight (the product) by the mean weight for the 294 cases. The Rescaled weight is the weight adjusted for non-response in the survey and the Rcensus weight is the Rescaled weight adjusted to 1996 population census proportions.

Questionnaires
Questionnaires
Data was collected from a stratified sample consisting of 294 households (103 Black; 126 Coloured; and 65 White) by means of four questionnaires: one directed at adults of 55 years and older; one at younger adults (between 18 and 54 years of age) and two focused on health (including anthropometric measurements) of adults and children. The survey instrument used was one that had been developed over a four year period and was the joint product of researchers at the University of Cape Town (Monica Ferreira, HSRC/UCT Centre for Gerontology, Karen Charlton, Nutrition and Dietetics Unit; and Jaqui Goldin, SALDRU); University of the Western Cape (Pieter le Roux, Economics); University of the Witwatersrand (Merton Dagut, and Martin Wittenberg, Faculty of Commerce); Rhodes University (Valerie Moller); the Medical Research Council (Krisela Steyn and Debbie Bradshaw); Princeton University (Anne Case and Angus Deaton, Economics and Woodrow Wilson School); Harvard University (Robert Jensen, Kennedy School of Government, and David Bloom, School of Public Health); MIT (Courtney Coile, Economics); the Health Systems Trust (Dr John Gear) and the Western Cape Provincial Dept. of Health (Drs. Najma Shaikh, Mike Hendricks & Ingrid le Roux) together with other persons in the medical community of South Africa. This team of gerontologists, economists, public health experts and physicians grappled with the survey design, both structure and content, through many rounds of piloting, until there was consensus that the questionnaire worked well in the field.
