The Organisation for Economic Cooperation and Development's Development Assistance Committee (OECD DAC) has published preliminary data for 2018, showing that official development assistance (ODA) fell by 2.7% in 2018. The data release is the first to use the OECD's new 'grant equivalent' methodology. Applied for the first time in 2018, the method aims to ‘provide a more realistic comparison of the effort involved in providing grants and loans and encourage the provision of grants and highly concessional loans, especially to low-income countries’.
Net ODA from DAC members reached US$153 billion in 2018. The largest donors in absolute amounts were 1) the US (US34.3 billion), Germany (US$25 billion), 3) the UK (US19.4 billion), 4) Japan (US$14.2 billion), and 5) France (US$12.2 billion). In relative terms, the largest donors were Sweden at 1.04% of its gross national income (GNI), Luxembourg (0.98%), Norway (0.94%), Denmark (0.72%) and the UK(0.7%).
