We use Demographic and Health Surveys (DHS) to compare poverty at two or more points in time within and between African countries. Our welfare measure is an index resulting from a factor analysis of various household characteristics, durables, and household heads' education. An advantage of this measure is that for intertemporal and intraregional comparisons, we need not rely on suspect price deflators and currency conversion factors. The wide availability and similarity of questionnaires of the DHS facilitate comparisons over both time and countries. Our results generally show declines in poverty during the previous decade, largely due to improvements in rural areas. (C) 2000 Published by Elsevier Science Ltd.
