Astrakhan Oblast is one of the most diverse parts of the country in terms of ethnic groups and languages.
The major groups are ethnic Russians (61% of the population), Kazakhs (17%) and Tatars (7%), but many others are also present and influence the shared local identity, culture and language varieties.
Being a regional rather than linguistic unity, Astrakhan Russian is a term for a broad group of dialects varying between speakers depending on their ethnicity, native language, age, education, occupation, location within the region and other social factors.
The main divide is that between Russians and people of other ethnic groups, as the speech of the latter is influenced by the vernacular languages of their communities.
It is not uncommon for people of minority background to grow up in an ethnically and linguistically diverse town or city in the region speaking only Russian, but their Russian typically still has traces of their heritage language.
