Minorities at Risk (MAR) Project (1945+)

Tracks 284 politically-active ethnic groups throughout the world -- identifying where they are, what they do, and what happens to them. Focuses specifically on ethnopolitical groups, non-state communal groups that have 'political significance' in the contemporary world because of their status and political actions. Political significance is determined by: (1) The group collectively suffers, or benefits from, systematic discriminatory treatment compared to other groups in a society and (2) The group is the basis for political mobilization and collective action in defense or promotion of its self-defined interests.
