Today there are close to 80,000 Khakas people. Most of them live in the Taiga regions on the northwestern slopes of the Sayan mountains in the Minusin Basin which contains the headwaters of the Abakan, Chulym and Yenisei Rivers. During the initial period of czarist colonization (the seventeenth and eighteenth centuries), the Khakas were known to the Russians as the "Yenisei Kirghiz."
The Altai who live in northern slopes of the Altai and Sayan mountains are divided primarily into two groups. The southern group is sometimes known as the Altai Kizhi (the word kizhi means "person" in Altai) after the largest of the four constituent groups; the remaining three are the Telengits, Telesy, and Teleuts). The northern group consists of the Tubalars, Chelkans, and Kumandins. They were were originally semi-nomadic taiga hunters and fishers.
The Taiga Yukaghirs live in the Upper Kolyma region in the Sakha Republic and in Srednekansky District. And there are also Yukaghirs that live in Tundra. the Tundra Yukaghirs live in the Lower Kolyma region in the Sakha Republic. There were three known surviving tribes from this Yukaghirs' group: the Odul of Nelemnoe, the Vadul of Andryushkino and the Chuvan of the Anadyr river area. The one who live in Taiga is Odul and they're also known as Taiga Yukaghir or Kolyma Yukaghir. Vadul lives in Tundra. Sometimes, Chuvan is considered as a different tribe (not belong to this group).
Bikin Udege is one of the Taiga tribes. To them, the Taiga means everything. The present population of Udege is less than 2,000, and the majority of them live in Khabarovsk in Far East Russia and coastal Russia. (The population of Russia is about 140 million.)
