Traditionally, Samoyedic languages and peoples have been divided into two major areal groups: Northern Samoyedic (Nenets, Yurats, Enets, Nganasans), and Southern Samoyedic (Selkups) with a further subgroup of Sayan-Samoyedic (Kamasins, Mators) named after the Sayan Mountains. This classification does not reflect linguistic relations, being purely geographical.
The most numerous of the Samoyedic peoples are the Nenets, who mainly live in two autonomous districts of Russia: Yamalo-Nenetsia and Nenetsia. Some of the Nenets and most of the Enets and Nganasans used to live in the Taymyrsky Dolgano-Nenetsky District. Most of the Selkups live in Yamalo-Nenetsia, but there is also a significant population in Tomsk Oblast.
↑0,2% of the population of Sayansky District (21 ppl) are declared as Kamasins and their descendants by the district administration in the official tourist guide (2021).
