The Kagera Health and Development Survey 2004 (KHDS 2004) took place in 2004 as a fifth round following on the four rounds of the baseline Kagera Health and Development Survey 1991-1994 (KHDS 91-94). The KHDS 2004 was designed to provide data to understand economic mobility and changes in living standards of the sample of individuals interviewed 10-13 years ago. The KHDS 2004 attempted to reinterview all respondents ever interviewed in the KHDS 91-94. This entailed attempting to track these individuals, even if they had moved out of the village, region or country.
