Siberia has population density of only three persons per square kilometer (comparable to Mongolia). The oblasts with the highest population densities are Chelyabinsk Oblast and Kemerovo Oblast, with 41 and 30 persons per square km, respectively. Koryak Okrug has population density of less than 0.1 per square kilometer.
Sakha (Yakutia) Republic, capital — Yakutsk, population 949,280 (2002) — the only Far Eastern region that is sometimes counted as part of Siberia.
Excluding territories of north-central Kazakhstan, Siberia has a total population of ca. 38.7 million (2005). The North Kazakhstan oblast has another 1.1 million inhabitants (2002).

About 70% of Siberia's people live in cities. Novosibirsk is the largest city in Siberia, with a population of about 1.5 million, followed by Yekaterinburg (1.3 million, Urals), Omsk (1.1 million), Chelyabinsk (1.07 million, in the Urals), Krasnoyarsk (0.91 million), Barnaul (0.60 million), Irkutsk (0.59 million), Kemerovo (0.52 million), Tyumen (0.51 million), Tomsk (0.48 million), Nizhny Tagil (0.39 million, Urals), Kurgan (0.36 million), Ulan Ude (0.36 million), Chita (0.32 million).
The above count, however, by including the entire Urals Federal District, includes cities not usually considered part of Siberia, i.e. Yekaterinburg, Chelyabinsk, and Nizhny Tagil.
Mongolic, Turkic and Manchu-Tungus languages are sometimes taken together under the term Altaic. At one time Uralic and Altaic were believed to form the Ural–Altaic group, though this theory has now been largely discarded.[citation needed] The proposed Uralo-Siberian family combines the Uralic family with the Yukaghir languages, Chukotko-Kamchatkan, and Eskimo–Aleut.[citation needed] These are more umbrella terms than accepted linguistic relationships.[clarification needed] The Yeniseian family, which includes Ket, has recently been linked with the Na-Dene languages into a Dené–Yeniseian group; while not universally accepted a broad consensus in favor of the proposal has emerged.[citation needed]
