To benchmark and monitor economic inequality across countries, the OECD relies on two dedicated statistical databases: the OECD Income Distribution Database (IDD), which offers data on levels and trends in income inequality and poverty, and the OECD Wealth Distribution Database (WDD), which collects information on the distribution of household net wealth. OECD IDD is updated on a rolling basis, two to three times a year. OECD WDD is updated every two or three years. If you wish to be informed by email when either database is updated, please contact Inequality.Contact@oecd.org.
