Ethnic Power Relations v.1.1
Up to date version of this dataset can be found at http://www.icr.ethz.ch/data/epr/#core
The Ethnic Power Relations (EPR) dataset identifies all politically relevant ethnic groups and their access to state power in every country of the world from 1946 to 2005. It includes annual data on over 733 groups and codes the degree to which their representatives held executive-level state power—from total control of the government to overt political discrimination.
Based on the input of dozens of regional and country specialists as well as independent research, EPR improves upon existing dataset that provide information on excluded demographic minorities only. EPR is a dynamic dataset that captures changes in ethnic politics over time, unlike static indicators such as ethnic fractionalization indices.
The EPR project is a collaborative effort between researchers at the ETH Zurich and the University of California Los Angeles.
