Geo-referencing of Ethnic Groups

Up to date version of this dataset can be found at

Whether qualitative or quantitative, contemporary civil-war studies have a tendency to over-aggregate empirical evidence. In order to open the black box of the state, it is necessary to pinpoint the location of key conflict parties. As a contribution to this task, this data project geo-references ethnic groups around the world. Relying on maps and data drawn from the classical Soviet Atlas Narodov Mira, the “Geo-referencing of ethnic groups” (GREG) dataset employs geographic information systems (GIS) to represent group territories as polygons.

The GREG dataset consists of 8969 polygons and is provided in ESRI shapefile format.
