The OECD’s aid statistics seek to inform taxpayers in OECD members and other countries about what is being spent on aid overseas. In doing so, they enable the public to see what governments are doing with their money. These statistics are completely transparent and publicly available to users.
ODA trends and statistics
The OECD is the only official source of reliable, comparable, and complete statistics on official development assistance (ODA). From high-level overviews to granular perspectives, OECD statistics on ODA help our users answer the question, “Who is spending what, where, and when?”
Key messages
The OECD’s database on individual aid activities, allows users to understand the key characteristics of ODA to help inform the policies and programmes of development co-operation providers in low- and middle-income countries.
The database, with information on more than 60 attributes variables for each activity, provides a comprehensive perspective on what ODA is doing worldwide.
Many OECD governments have agreed to international commitments, enshrined in domestic legislation, on where and how to spend their aid to maximise results or benefit the neediest countries.
An example is the UN target to spend 0.7% of a provider’s national wealth on ODA. The OECD’s aid statistics help to hold its members and other providers accountable to meeting such commitments.
Members of the Development Assistance Committee (DAC) are required to report their ODA statistics to the OECD. Many bilateral providers outside of the DAC have been reporting their statistics to the OECD on a voluntary basis, as have multilateral agencies on outflows from their core resources.
These initiatives have improved the OECD’s ability to provide a comprehensive perspective on development finance flows to partner countries.
Context
Official development assistance in historical perspective: 1960-2025
ODA declined by 23.1% in 2025, representing both the largest annual contraction on record and a second consecutive year of decline. This downturn brings ODA back to its lowest level in ten years. Germany, the United States, the United Kingdom, Japan and France (ranked by ODA volume) accounted for 96% of the total decline in ODA.
Official development assistance to vulnerable populations
In 2025, ODA from DAC member countries to least developed countries fell by 25.8%, while support to sub-Saharan Africa decreased by 26.3%. Humanitarian ODA contracted for the second consecutive year, ending a period of sustained growth from 2019 to 2023. ODA allocated to in-donor refugee costs also dropped again this year by 22.1% compared to 2024.
Finance supporting gender equality dropped in 2024
A decade-long trend of rising volumes of ODA to advance gender equality is coming to an end. From 2023 to 2024, bilateral allocable ODA with gender equality objectives dropped by 13%. This is the lowest volume since 2021. The share of aid integrating gender equality objectives also fell from 49% in 2023 to 47% in 2024.
