The World Inequality Database on Education (WIDE) brings together data from Demographic and Health Surveys and Multiple Indicator Cluster Surveys from over sixty countries to enable users to compare education attainment between countries, and between groups within countries, according to factors that are associated with inequality, including wealth, gender, ethnicity and location. Users can create maps, charts, infographics and tables from the data, and download, print or share them online.
