DAC have tracked financial flows to countries in the global south for over 50 years, with special attention paid to ODA (Official Development Assistance). ODA includes official grants or loans made to developing countries (or multilateral agencies,) which promote economic development and welfare, and are provided at concessional financial terms.

To allow comparisons between countries over time, DAC reports aid flows in US dollars at constant prices (these are the figures used in this blog). Most donor countries have long signed up to the principle of spending 0.7% of GNI on ODA, but this ambition has never been met on a global scale.
