History

The World Inequality Database was initially created as the The World Top Incomes Database (WTID) in January 2011 with the aim of providing convenient and free access to all the existing series. 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.

In December 2015, the WTID was subsumed into the WID, The World Wealth and Income Database.  In addition to the WTID top income shares series, this first version of WID included an extended version of the historical database on the long-run evolution of aggregate wealth-income ratios and the changing structure of national wealth and national income first developed by T. Piketty and G. Zucman 2013, 2014
