EPR - Ethnic Power Relations

The Ethnic Power Relations (EPR) Core Dataset 2018 is based on the original dataset EPR v.1.1 and identifies all politically relevant ethnic groups and their access to state power in every country of the world from 1946 to 2017. It includes annual data on over 800 groups and codes the degree to which their representatives held executive-level state power—from total control of the government to overt political discrimination.

Data

The current version of the EPR data is available in research-ready country-year and group-year format from the GROWup Research Front-End data portal.
