This booklet celebrates 50 years of the OECD’s statistics on aid and other flows to developing countries. Compiled under the guidance of the OECD’s Development Assistance Committee (DAC), these statistics are the basis of practically all international comparisons of aid volume. They are relied on by governments, NGOs, the media, researchers and students as a key source of information on the volume and quality of aid.
The DAC has measured resource flows to developing countries since 1961. Special attention has been given to the official and concessional part of this flow, defined as “official development assistance” (ODA). The DAC first defined ODA in 1969, and tightened the definition in 1972. ODA is the key measure used in practically all aid targets and assessments of aid performance.
