This factsheet analyses several major international finance flows between 2000 and 2021 to countries which were eligible to receive Official Development Assistance (ODA).1 Focusing predominately on 2021 – the latest year for which data is available for all the flows analysed in this factsheet – it provides an update on a previous factsheet published in 2018. The 2018 paper described key trends in international sources of finance over time and assessed their relative level of significance. In 2021, ODA continued to be a critical source of finance,2 particularly to least-developed countries (LDCs) and to countries in fragile situations.3 However, commercial flows still dominated the international financing landscape; these and other international financial flow trends will be explored in this factsheet.
