First, accept our apologies. The key novelty has been to combine fiscal, survey and national accounts data in a systematic manner. In such cases we review all existing series and attempt to combine them in the most sensible manner.

New: WID.world now displays inequality estimates for all countries. By doing so, it becomes possible to track very precisely the evolution of all income or wealth levels, from the bottom to the top. This indicator has a different unit, selecting it will unselect the others. First, we release detailed series for national wealth accounts, which usually cannot be found on other portals.

(Source: United Nations World Income Inequality Database) The Gini-coefficient measures wealth distribution The work on top income shares was recently extended to study the long run evolution of top wealth shares (see E. Saez and G. Zucman 2016, F. Alvaredo, A. Atkinson and S. Morelli 2017, and B. Garbinti, J. Goupille and T. Piketty 2016). This is fully explained in the country-specific papers. WID, also referred to as WID.world, is an open source database, that is part of an international collaborative effort of over a hundred researchers in five continents. This allowed us to compute longer and more reliable top income shares series than previous inequality databases (which generally rely on self-reported survey data, with large under-reporting problems at the top, and limited time span). New: WID.world now displays inequality estimates for all countries. It should also be noted that default monetary values for Eurozone countries are displayed in PPP Euros and are thus different from Market exchange rate Euros.

Over the past decades, the increase in economic inequalities was largely driven by a rise in income and wealth accruing to the top of the distribution. There are now more than 3,600 unique country-year observations in … All these methodological choices can explain slightly different values between WID.world and other data portals. We changed the name of the database from WTID to WID in order to express the extension in scope and ambition of the database, as well as the new emphasis on both wealth and income. They are described in the Metadata associated to each variable and in the associated methodological documents. Income Inequality Data 8 November 2018 There has been much progress in improving the availability, quality and comparability of income and wealth inequality data. WID.world overcomes this limitation by combining different data sources: national accounts, survey data, fiscal data, and wealth rankings.

Atkinson and Alan Harrison 1978, and extends it to many more countries and years. Thanks to the continuous cooperation of the WID.world Fellows, we pursue our efforts to expand the database into three major directions. Thanks to the contribution of over a hundred researchers, the WTID expanded to include series on income inequality for more than thirty countries, spanning over most of the 20th and early 21st centuries, with over forty additional countries now under study. We attempt to combine the different data sources available (in particular fiscal data, survey data and national accounts) in a more systematic way than what was done to date, but more progress is yet to come.
