Our colleague Johannes points us to AidData.org:
AidData is a collaborative initiative to provide products and services that promote the dissemination, analysis, and understanding of development finance information. At the core of the AidData program is the AidData web portal, which is a gateway to nearly 1 million records of development finance activities from donors around the world. Complementing the work of the OECD, whose Creditor Reporting System (CRS) is the official source of statistics for all OECD member countries, the AidData portal aims to provide access to development finance activities from a wide range of donors in an accessible format. In addition to providing access to these data, the team works on other projects that make it easier to access and analyze aid information, such as geocoding.
