OECD Income (IDD) and Wealth (WDD) Distribution Databases

 

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.

Quality reviews (IDD)

This quality review (December 2012) is in three main parts:
-Part I reports the results of a first self-assessment of different quality dimensions of the OECD Database on Household Income Distribution and Poverty (.pdf)
-Part II assesses the cross-country comparability of the OECD Earnings Distribution Database (.pdf)
-Part III provides detailed country data reviews on income distribution data, for the 34 OECD member countries. These country reviews compare the OECD benchmark series for income distribution and poverty reporting with alternative estimates which are available on a national or international basis -  each country separately (.pdf) including revised versions:
