In the last decades, many large-scale representative household surveys have been conducted in developing countries. In these surveys, for millions of individuals, demographic, socio-economic, health and other information has been collected. At this moment, the data from these surveys cover over 100 countries in all regions of the developing world.

In the Database Developing World (DDW) these datasets are brought together, made comparable, and enriched with contextual data at the subnational and national level. In this way, a unique window to the developing world is created that makes it possible to study important processes taking place there on a scale and with a degree of detail that has never been possible before.
