This article is devoted to the problem of maintaining and preserving the ethnic culture and language of the Chuvash living in Western Siberia. The purpose of the work is to initiate the beginning of linguistic and, in general, ethnographic studies of this diaspora group of the Chuvash people, the existence of which is an interesting scientific problem. The author mainly relies on the already published scientific developments of Siberian scientists. In fact, these studies are written in the genre of an essay. It provides information about the language, demographic situation, folklore and religion of the Chuvash of the specified region. Studies have shown that the Chuvash of the metropolis and Siberia retain many common features in traditions, customs, religious practice and culture. Their first generation tries to preserve the ethnic culture to the maximum extent possible. The new settlers, as a rule, speak the language and observe the traditional ritual and festive culture, while representatives of the Chuvash Republic often take a significant part in their life. Subsequent generations are more exposed to the processes of language shift and de-ethnization. Observations show that in order to maintain and preserve an ethnic culture, it is extremely important to recognize the need to maintain an ethnic language.
