Figure: The erosion of the middle class share in market income
All the Ginis (ALG) dataset (version: October 2016)
This dataset represents a compilation and adaptation of income or consumption Gini coefficients retrieved from nine sources in order to create a single “standardized” Gini variable. The dataset was intentionally created in a flexible format so that every user can decide to use just one or two of these sources or to combine several sources in a particular way. The Ginis cover the period 1950-2015 and include 166 countries. There are more than 5,000 Gini values (all coming from nationally representative household surveys).

World Income Distribution (WYD) dataset 1988-2008
World wide household survey data (1988-2005), from approximately 120 countries, arranged mostly by income or consumption ventile, and used in several papers, and in the books Worlds Apart: Measuring International and Global Inequality (Princeton University Press, 2005) and The Haves and the Have-Nots: a Short and Idiosyncratic History of Global Inequality (Basic books, 2010) can be downloaded here. The data are in Stata10 and for five benchmark years: 1988, 1993, 1998, 2002 and 2005 (in a single file), plus there is an update for 2008.

Lakner-Milanovic World Panel Income Distribution
This database contains a panel of country-deciles covering the twenty year period 1988-2008, expressed in common currency and prices (2005 Purchasing Power Parity (PPP) dollars derived from the 2005 International Comparison Project). The database allows comparisons of average incomes by decile both across time and across countries. The data, explanation of the variables and the relevant papers can be downloaded here:
