Achieving global development objectives depends on involving stakeholders in aid-funded work, strengthening accountability of donor agencies and partner governments, and building country ownership. Yet sometimes even basic information such as the location of an aid project is difficult to find. Information on project locations is critical for determining whether aid is reaching areas of greatest need, as well as for avoiding duplication of effort within a country. Geocoding, or recording the location of aid projects at the sub-national level, enables visual tracking of where the money is flowing and what kind of aid each area is receiving.

AidData, in collaboration with Uppsala University, has developed a comprehensive way to geocode aid projects. AidData is a collaboration between Brigham Young University, the College of William and Mary, and Development Gateway. By defining multiple levels of geographical precision, AidData is able to accurately identify the locations of all types of development projects. Using our rigorous yet flexible methodology, teams of trained researchers work with donor and government agencies to determine the precise location of development activities. Mapping this information then enables a better understanding of the allocation of aid within a country, highlighting any potential financing gaps, displaying inequities of aid distribution, and ensuring that aid money flows to those who need it most. Recent work includes the Mapping for Results partnership with the World Bank Institute, where 1200 projects were geocoded using our methods. Maps of the results for about 70 countries are available at

The State of Data in DG’s Work

As we review our strategy, we plan to share here much of what we’ve learned through programming in more than a dozen countries – from our work and from our excellent partners – about the state of data in agriculture, tobacco control, open contracting, and the extractive industries. For each theme, we’ll explore who are the key data users, the decisions they make, the most important data gaps, and the crucial risks of data (mis)use. Here we share previews from some of our flagship programs.

HIV/AIDS Response Through Youth-Led Community Mapping in Côte d’Ivoire

With support from DCDJ, local youth in Côte d’Ivoire organized a successful mapathon to get community resources, landmarks, and risk zones in Daloa – particularly those relevant to young people – on the map. Through the process, they acquired new skills including OSM tracker to develop map layers, how to collect local data, and how to communicate results stored in a new database developed through the program.
