World Bank Development Research Group

The World Bank Development Research Group undertakes research across the broad spectrum of development issues, including health, social protection and poverty. The bank itself works across the developing world, providing financial assistance to client countries in the form of loans and grants, as well as technical assistance and analytic and advisory work to client governments. The work of the research group feeds into the activities of the rest of the bank, helping to shape thinking on priorities and policy reform options, generally and within specific sectors. The bank’s work in general helps identify issues and challenges for the research group to work on, and provides it with unrivalled access to information, data and policymaking at the global and country levels.

The World Bank is not an official funded partner within the HEFPA programme.
