Based on the annual percentage of ethnic groups in each country The Historical Index of Ethnic Fractionalization (hereafter, HIEF) calculates the degree of ethnic fractionalization (EF) using the most universally applied formula in the empirical literature, which is a decreasing transformation of the Herfindahl concentration index.
Where EFc is the level of ethnic fractionalization in country c, i indexes ethnic groups and Si is the proportion of the population in unit c belonging to ethnic group i (i = 1, …, n).
