The Demographic and Health Surveys (DHS) project is the third consecutive worldwide research project initiated by the U.S. Agency for International Development (USAID) to provide data and analysis on the population, health, and nutrition of women and children in developing countries. Its two predecessors, the World Fertility Survey (WFS) and the Contraceptive Prevalence Surveys (CPS), paved the way for the DHS project by focusing their research on questions related to fertility, family planning, and mortality. They also helped develop DHS' current reputation as a leader in the field of demographic and health research.

Demographic and Health Surveys (DHS) are nationally-representative household surveys with large sample sizes (usually between 5,000 and 30,000 households). DHS surveys provide data for a wide range of monitoring and impact evaluation indicators in the areas of population, health, and nutrition.
