AidData Center for Development Policy

USAID from the American people

The AidData Center for Development Policy (the AidData Center) provides geospatial data and tools that enable the global development community to more effectively target, coordinate, and evaluate aid. Working in partnership with USAID country missions, host governments and civil society groups, the AidData Center pinpoints the precise geographic locations of development projects and creates subnational maps and dashboards that overlay geocoded project data with high-resolution spatial data on poverty, disease, violence, environmental degradation, and governance. These data and tools make it possible to visualize and analyze where funds are going at the subnational level compared to the areas of greatest need and opportunity.

Headquartered at the College of William and Mary in Williamsburg, Virginia, the Center has five main focus areas:

Geocoding aid projects

AidData pinpoints the locations of development activities, and design tools to visualize this information and support monitoring of aid distribution and impact.

Building an AidData Research Consortium

AidData mobilizes experts across seven thematic areas to analyze development trends using geospatial information and inform evidence-based policy decisions.

Boosting government capacity

AidData increases the capacity of governments to capture granular information on their development portfolio and use this to manage development finance flows.

Equipping students, faculty, and civil society organizations

AidData provides tools and training for non-governmental actors to map the distribution of development resource flows and monitor results.

Developing tools to support research and practice

AidData designs tools for researchers, policymakers, and practitioners to visualize multiple data sources and uncover otherwise difficult-to-observe relationships.

Capacity Building Spotlight: AidData Summer Fellows

Eleven student researchers from the College of William & Mary and University of Texas-Austin deployed in the summer of 2013 to Nepal, Uganda, Timor-Leste, Senegal, and Mexico to serve as AidData Summer Fellows embedded within local universities, civil society organizations and research institutes. These summer fellows improved the capacity of developing country stakeholders to use geocoded data to address their existing initiatives and goals. Funded by USAID’s Higher Education Solutions Network, fellows held trainings for NGO, civil society and university stakeholders in ArcGIS software and the AidData/UCDP geocoding methodology – applying precise geographic coordinates to the locations of aid activities.
