Africa is the world region with the least information on population health. Most civil registration and vital statistics systems in Africa cover a small fraction of the population and produce data that are not useful. Consequently, the empirical basis for understanding population dynamics and population health in Africa is surprisingly thin. Professor Sam Clark will speak about over 20 years of steps and missteps working in the field and with African institutions engaged in a range of data collection and training activities. Much of the presentation will be about work with demographic and health surveillance system sites and the epidemiological and demographic research and training work that they do.
