Foreign aid matters to low-income countries. Official Development Assistance, or ODA, is aid that supports economic development in specific areas like health, education and infrastructure. It can make up two-thirds of all external financing for the least well-off nations.

The United Nations calls for the world's richest countries to donate 0.7% of their gross national income (GNI) as foreign aid. But only a handful of countries hit that target, and an increasing number of nations have signalled they intend to slash their foreign aid budgets going forward.

Read on to see who’s the most generous and who gives the least, based on data from the Organisation for Economic Co-operation and Development (OECD) for 2023, the most recent full year available. Countries are ranked by the percentage of GNI donated.

All dollar amounts in US dollars.

How much do the world's richest countries really donate in foreign aid?
