Development Data Library

An Effort of USAID AidScape


The Development Data Library (DDL) is USAID’s public repository of Agency-funded, machine readable data. The DDL is part of USAID’s commitment to evidence-based programming and rigorous evaluation.  In October 2014, USAID announced its first ever open data policy, Automated Directives System (ADS) 579 – USAID Development Data.
