Siberian Tatars (), the ethnographic and ethnoterritorial group of Tatars of Western Siberia, the indigenous Turkic-speaking population of the forests and steppes of Western Siberia, originate in areas stretching from somewhat east of the Ural Mountains to the Yenisey River in Russia. The Siberian Tatars call themselves Yerle Qalıq ("older inhabitants"), to distinguish themselves from more recent Volga Tatar immigrants to the region. The word "Tatar" or "Tadar" is also used as a self-designation by some closely related Siberian ethnic groups, namely the Altaians, Chulyms, Khakas, and Shors. The 2010 census counted more than 500,000 people in Siberia defining their ethnicity as "Tatar". About 200,000 of them are considered indigenous Siberian Tatars. However, only 6,779 of them called themselves "Siberian Tatars". It is not completely clear which part of those who called themselves "Siberian Tatars" consider themselves to be a separate ethnos and which part as a group into the Tatar people, because the census took into account the Siberian Tatars as a subgroup of the Tatar ethnos. , the Siberian Tatars do not yet have public education available in their own language. Lessons in the local schools are taught only in the Russian and Volga Tatar languages. Population Siberian Tatars historically lived in the vast territory stretching from around the Yenisey River all the way to the area lying somewhat east of the Ural Mountains. According to the ambassadors of the Siberian Khanate ruler Yediger Khan, who visited Moscow in 1555, the population of "the black people", not counting the aristocracy, was 30,700. In a decree concerning tribute issued by Ivan the Terrible, the population was given as 40,000. According to the results of the 1897 All-Russia Census, there were 56,957 Siberian Tatars in the Tobolsk Governorate. This was the last accurate information about this population. In later censuses, Tatar immigrants from the other regions of Russia were also recorded under the classification of Tatar. The Siberian Tatars tried to avoid the census as much as possible, as they believed that it was an attempt to force them to pay the Yasak (tribute). Their population in the territory of the current Tyumen Oblast in 1926 was recorded as 70,000; in 1959 as 72,306; in 1970 as 102,859; 136,749 in 1979; 227,423 in 1989; and 242,325 in 2002. According to the results of the 2002 Russian Census, there were 385,949 Tatars living in the oblasts discussed above. (Their territory roughly
