This paper introduces a new quinquennial dataset of educational inequality disaggregated by age group for 146 countries, from 1950 to 2010, by using the Gini index of education as a measure of the distribution of years of schooling. Based on recent estimates of average years of schooling from Barro and Lee (2010), our calculations take into consideration, for the first time, the changes over time in the duration of educational stages, in each country and for each age group. The downward trends in educational inequality observed during the last decades depend on age group, gender, and development level.
