This study explores the consequences and origins of between-ethnicity economic inequality both across and within countries. First, combining satellite images of nighttime luminosity with the historical homelands of ethnolinguistic groups we construct measures of ethnic inequality for a large sample of countries and show that the latter is strongly inversely related to comparative development. Second, differences in geographic endowments across ethnic homelands explain a sizable portion of ethnic inequality contributing to its persistence over time. Third, exploiting across-district within-African countries variation using individual-level data on ethnic identification and well-being from the Afrobarometer Surveys we find that between ethnic-group inequality is systematically linked to regional under-development. In this sample we also explore the channels linking ethnic inequality to (under) development, finding that ethnic inequality maps to political inequality, heightened perceptions of discrimination and undersupply of public goods.
