I need geo-referenced data on ethnic groups specifically in Russia (global data would work fine also as long as it includes Russia).
So far I can only find the GREG dataset: http://worldmap.harvard.edu/data/geonode:GREG_0vV.
However, this data is based on the classical Soviet Narodov Mira or "Atlas of the peoples of the world" which was completed in 1964. The population movements that occurred with the fall of the Soviet Union with ethnic groups returning to ancestral lands after forced relocation, this data seems outdated especially in the periphery and Southern regions of Russia.
Does anyone know of contemporary geo-referenced ethnic group data for Russia?
