Ethnic Power Relations (EPR)
The well-known Ethnic Power Relations dataset identifies all politically relevant ethnic groups and their access to state power in all countries from 1946 onwards. It includes over 800 groups and codes the degree to which their representatives held executive-level power—from total control of government to overt political discrimination. New coding markers distinguish group members by religion, language, race, etc. Additional datasets provide geospatial data; ethnic conflict data; transborder ethnic data; linguistic, racial & ethnic cleavages of groups; ethnicity of refugees
