ETHNIC POWER RELATIONS DATA SET, Version 3 (1946-2010)
Ethnic Power Relations (EPR) Version 3
identifies all politically relevant ethnic groups and their access to state power
in every country of the world from 1946 to 2010. It includes annual data on
almost 800 groups and codes the degree to which their representatives hold
executive-level state power — from total control of the government to overt
political discrimination.
The first version was produced in collaboration with researchers from the ETH Zürich (click here for EPR Version 1, including a geo-coded version). Version 3 extends to 2010 and improved the coding of much of Latin America, Central Asia, Eastern Europe, and many other countries. It was produced by a team of researchers at UCLA.

Coding rules for types of ethnic markers
Minor and Major Ethnic Armed Conflicts, 1946-2010
A recoding of the PRIO/Uppsala Armed Conflicts Data Set to identify ethnic and secessionist conflicts. The Ethnic Armed Conflict dataset is compatible with the EPR Version 3 dataset and is integrated in the above stata files.
NATIONAL PRIDE AND ETHNOPOLITICAL POWER (REPLICATION DATA)
This dataset combines representative survey data from 123 countries around the world and records responses to an identical question: "How proud are you to be of XY nationality"? The dataset also contains information, for a reduced sample of 64 countries, on the ethnic background of individuals, using EPR's group list and power status variables.
FROM EMPIRE TO NATION-STATE (REPLICATION DATA)
Territorial Data, 1816-2001
Takes fixed geographical territories instead of countries
as units of analysis, enabling the tracing of a territory’s political and
economic development before and after independence from 1816 to 2001.
1816-2001
Identifies the location and purpose of all 464
major wars since 1816, expanding substantially on previous efforts by
including wars fought in all polities, including pre-independent kingdoms and
empires. The data complements standard war datasets that characterize wars
only by the state participants that fight them.
The dataset and coding rules are described in Wimmer and Min. “The location and purpose of wars around the world, 1816-2001", in International Interactions 35(4):390-417, 2009. Download article
NATION-STATE FORMATION ACROSS THE WORLD (REPLICATION DATA)
Contains variables indicating economic, political, and cultural modernization processes on the world's territories before they transition to the nation-state, the presence of nationalist organizations, wars, dependency from imperal centers, the power of these centers, the years in which a territory transitions to the nation-state, etc. It covers 140 territories (in their post-independence geographic extension) and years from 1816 onward.
