The EPR-Organizations (EPR-O) dataset
EPR-O is a new cross-national dataset on ethno-political organizations. Building on the EPR dataset (see below), it identifies individual organizations representing groups listed in EPR. It currently covers a random sample of 40 countries over the period 1946-2013, including over 600 distinct organizations, and provides yearly codings of these organizations' political demands, the ethnic groups they claim to represent, and their means of group representation, ranging from electoral participation to violence. The EPR-O dataset can be used both for organization-level analyses and, in conjunction with EPR, in aggregated form to study ethno-political mobilization at the ethnic group level.

The Ethnic Power Relations (EPR) dataset
The EPR dataset identifies politically relevant ethnic groups and provides annual codings on their access to executive state power in all countries of the world with a population, in 1990, of at least 500,000.
You can access the most current EPR 2018 data here or through ETH’s GROWup web portal.

Ethnic civil society organizations in Latin America
For my article on "Indigenous Movements and Ethnic Inclusion in Latin America", published in International Studies Quarterly, I have composed the first cross-sectional dataset on ethnic civil society organizations in Latin America. The original dataset covered the period 1946-2009 and has now been updated to 2017. This Excel file provides both the raw list of organizations and the aggregated ethnic group-level indicator of the number of organizations by group-year. Through the group name, country ID, and year variables, the data can be matched with the EPR dataset.
