The ETH has taken up the further development of the “Ethnic Power relations” dataset. It comprises all politically relevant ethnic main groups, differentiated between common linguistic, somatic and religious aspects, for 155 sovereign states from 1946 to 2017. Politically relevant means either that at least one actor active in political life (political organisation) claims to represent the political interests of an ethnic group or that members of single ethnic groups are systematically and purposefully discriminated against. The participation of ethnic groups are divided into those that participate in the political arena (monopoly, dominant, senior partner, junior partner) and those who do not (regional autonomy, powerless, discriminated).
