The OECD National Accounts Statistics database includes annual and quarterly data of a wide range of areas from 1955, such as gross domestic product (GDP) with its three approaches: expenditure based, output based and income based; gross domestics product (GDP) per capita; disposable income; population and employment; PPPs and exchange rates; general government accounts; financial accounts flows and stocks and central government debt for OECD countries and non-member economies. Data are internationally comparable based on the System of National Accounts 2008 (SNA 2008).
