This dataset and predefined summary tables are a complement to the report Agricultural Policy Monitoring and Evaluation 2025, which monitors agricultural policy developments in 38 OECD member countries, 5 non-OECD European Union member states and 11 emerging and developing economies: Argentina, Brazil, People’s Republic of China, India, Indonesia, Kazakhstan, the Philippines, the Russian Federation, South Africa, Ukraine and Viet Nam.

The OECD uses a comprehensive system for measuring and classifying support to agriculture - the Producer and Consumer Support Estimates (PSEs and CSEs) and related indicators. They provide insight into the increasingly complex nature of agricultural policy and serve as a basis for OECD's work on agricultural policies.

The commodities used in this dataset have been reviewed and mapped to the Central Product Classification (CPC) Version 2.1 where relevant to facilitate international comparison. The mapping can be found here
