Basic results of our research of ethnic identity as a major indicator of social-psychological adaptation with some Caucasians by birth (Azerbaijanians, Armenians, Chechens) having large diaspores in the Saratov region and the indigenous Russian population of the Saratov region as an example are presented. A comparative analysis of such indicators of ethnic identity as the positivity/negativity of auto- and heterostereotypes, feelings experienced to their own ethnic group, and aims at interethnic interactions is given.
