This article examines the content of a web-based repository of published impact evaluations of international development interventions. To populate this repository, we conducted a systematic search and screening process. We find that of the 2259 studies published from 1981 to 2012, annual publication increased dramatically after 2008. Most studies are on health, education, social protection and agriculture and are concentrated in South Asia, East Africa, South and Central America and Southeast Asia. There are statistically significant differences in time between end line data collection and publishing by the publication type, and institutional affiliation of authors has shifted towards countries in North America and Europe.

The International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding and producing high-quality evidence of what works, how, why and at what cost. We believe that better and policy-relevant evidence will make development more effective and improve people's lives.3ie evidence gap map reports 3ie evidence gap maps are thematic collections of information about impact evaluations and/or systematic reviews that measure the effects of international development policies and programmes. The maps present a visual overview of existing and ongoing studies in a sector or subsector in terms of the types of programmes (or interventions) evaluated and the outcomes measured. The evidence gap map reports provide all the supporting documentation for the maps themselves, including the background information for the theme of the map, the methods and results, including the protocols and the analysis of the results.

The International Initiative for Impact Evaluation (3ie) promotes evidence-informed equitable, inclusive and sustainable development. We support the generation and effective use of high-quality evidence to inform decision-making and improve the lives of people living in poverty in low-and middle-income countries. We provide guidance and support to produce, synthesise and quality assure evidence of what works, for whom, how, why and at what cost. 3ie evidence gap map reports 3ie evidence gap maps are thematic collections of information about impact evaluations or systematic reviews that measure the effects of international development policies and programmes. The maps provide a visual display of completed and ongoing systematic reviews and impact evaluations in a sector or subsector, structured around a framework of interventions and outcomes.The evidence gap map reports provide all the supporting documentation for the maps, including the background information for the theme of the map, the methods and results, protocols, and the analysis of results.

This is a list of impact evaluations of interventions in low-income and middle-income countries published between January and May 2010. If you would like to submit a newly published study for inclusion in the next 'Recent Impact Evaluations', please submit details of the study to database@3ieimpact.org. All listed studies will also be included in the 3ie database of impact evaluations accessible at: http://www.3ieimpact.org/database_of_impact_evaluations.html
