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 1950-2012 and include 166 countries. There are more than 5,000 Gini values (all coming from nationally representative household surveys).
