Most OECD Member countries produce both annual and quarterly national accounts. National accounts are established in line with international accounting standards, as put down in the System of National Accounts 1993.

National accounts are important tools in economic analysis and forecasting. While annual accounts offer greater depth and comprehensiveness, quarterly accounts are more focused and more rapidly available.

National accounts data are used by government, the private sector and academia in their assessment and analysis of economic developments.

Links to methodological sources can be found under Annual National Accounts and Quarterly National Accounts.

Methodological work in areas related to national accounts includes two OECD Manuals: Measuring Productivity and Measuring Capital.
