Chuvash language
Chuvash is the native language of the Chuvash people and an official language of Chuvashia. It is spoken by 1,640,000 persons in Russia and another 34,000 in other countries. 86% of ethnic Chuvash and 8% of the people of other ethnicities living in Chuvashia claimed knowledge of Chuvash language during the 2002 census. Despite that, and although Chuvash is taught at schools and sometimes used in the media, it is considered endangered, because Russian dominates in most spheres of life, and few children learning the language are likely to become active users.
