Updated Version of World Income Inequality Database now Freely Downloadable

The updated WIID, Version 3.A, gives researchers access to data on eight new countries and over 2000 additional observations as well as numerous corrections to the previous dataset.

Thee period covered by the data base has been extended by seven years in this new version, with the latest observations now coming from 2012. Quality ratings of the data provide researchers with the ability to decide for themselves which measurements to include in their analysis.

Since its first publication in 2000 the WIID has become a vital resource for all those interested in the study of inequality, and has made significantly easier the task of comparing income inequality over time and time and space.

The updated WIID will continue to contribute to better-informed studies of inequality, and increase debate about its causes and consequences.

WIID V3.A can freely be downloaded here.
