"The Ket language belongs to the Ket Assan (Yenisey) group of the Paleo-Asiatic languages. Kott (Kot), Arin, Assan (Asan) also belong to this group but these people have been assimilated by either the Khakass, Evenks or Russians. The Kets are the only living people of the western Paleo-Asiatic group.

"The population of the Kets has been more or less stable, but the percentage of native language speakers is on the decline. In 1926 there were 1,225 speakers, but after 53 years only about 500 were reported -- less than half of the population. "
