OECD Income Distribution Database (IDD): Gini, poverty, income, Methods and Concepts


To benchmark and monitor income inequality and poverty across countries, the OECD relies on a dedicated statistical database: the OECD Income Distribution Database which offers data on levels and trends in Gini coefficients before and after taxes and transfers, average and median household disposable incomes, relative poverty rates and poverty gaps, before and after taxes and transfers, etc. Due to the increasing importance of income inequality and poverty issues in policy discussion, the database is now annually updated. If you would like to be informed by email when the database is updated, please contact
