The Development Evidence Portal (DEP) is the world’s largest database of impact evaluations and systematic reviews on interventions to improve lives in low- and middle-income countries. It is updated monthly and contains more than 10,000 impact evaluations, systematic reviews and evidence gap maps. The DEP provides advanced searching capabilities and a rich set of options for filtering studies to help you find the evidence you need.

Of the 72 new studies we added to the EGM in this round, as many as 24 per cent evaluate interventions at the national or transnational scale. In this blog, we explain how this is a remarkable increase over the original map.
