Siberia (North Asia), including the Russian Far East, geographicaly, is the Asiatic part of Russia. As a result of the Slavic-Russian conquest of Siberia (17th to 19th centuries) and of the subsequent population movements during the Soviet era (1917-1991), the demographics of Siberia today is dominated by speakers of Russian. However there remains a slowly increasing number of indigenous groups, between them, accounting for about 10% of the total Siberian population (about 4,500,000), some of which are closely genetically related to indigenous peoples of the Americas.
