Among the largest non-Slavic group of Russian citizens of Siberia are the approximately 400,000 ethnic Volga Germans [REF].
According to the 2002 census there are 500,000 Tatars in Siberia, but of these, 300,000 are Volga Tatars who also settled in Siberia during periods of colonization and are thus also non-indigenous Siberians, in contrast to the 200,000 Siberian Tatars which are indigenous to Siberia [REF].
