This is an overview of the leading prospective studies in developing countries on population and health research. Prospective community studies are concerned with understanding the incidence of birth, disease, and death. Here, the leading practitioners in this field present the methodologies they have developed and summarize the major findings of their efforts. Since many of these methodologies have never been documented and their results are scattered in different publications, this volume collects much valuable data that is otherwise difficult to locate. It will be an indispensable guide to researchers in the field of prospective studies and will also prove useful as an academic or professional resource for demographers, public health researchers, family planners, and survey specialists.
