In this paper, we update the work by Palloni and Lee and use a modified version of their model to calculate the demographic impact of HIV/AIDS on the elderly. Our evaluation rests on newly available data for South Africa as a whole and its provinces. Our central objective in this paper is rather modest since we only estimate the effects of HIV/AIDS on residential patterns of the South African elderly and evaluate observable changes in living arrangements of the elderly over less than a decade. We eschew assessment of other effects of the epidemic on the elderly but argue that these may be reflected, at least in part, in changes in residential arrangements. We use information from three data sources collected before and after the onset of the HIV/AIDS epidemic in South Africa: the 1991 census of the Republic of South Africa, the 10% sample of South Africa’s first post-apartheid census conducted in 1996, and South Africa’s 1998 Demographic and Health Survey (DHS).
