Digital tools have revolutionized the ways in which we interact with the world around us. Since its creation, the Center for Digital Development, a part of USAID's U.S. Global Development Lab, has helped the Agency adopt new approaches to incorporating these digital tools into development projects and programs. The 2017 Digital Download provides an overview of the Center's recent accomplishments, focusing on what we believe are the critical foundations of a sustainable digital economy--digital inclusion, digital finance, digital information systems, and advanced data and geospatial analysis.
