Introduction. In multiethnic societies, the issues of interaction between different peoples is the subject of monitoring, as well as of constant attention, on the part of the government as a measure of preventing any contradictions and complications in this area. The article aims at studying the populations’ attitudes and perceptions in terms of local and national (federal, Russian) identities in the Republics of Bashkortostan and Tatarstan, as well as the degree of their involvement in the global social transformations of the Russian society at large. Data and methods. The research focuses on the analysis of the results of 2020–2021 surveys of the population of the two neighboring republics conducted within the framework of the Project «Preservation and development of the ethnocultural and linguistic diversity of the republics as a condition for promoting Russian federalism». When selecting the objects for the research the authors were guided by the fact that Bashkortostan and Tatarstan are leading subjects of the Russian Federation both in terms of socio-economic development and an awareness of civil and ethnic identities. Results. The study shows that while their ethnic (regional) identities have recently been of relevance for the populations in both republics, at the same time, there is a growing awareness of their national (federal) identity; there is an interest in promoting institutes of civil society, as well as in facilitating greater access to active involvement of the people in the economic, social, and public processes. Sociological surveys help correct approaches, as well as clarify and specify some concepts related to ethnological issues. This article, for example, includes analysis of various types of identities, including such concepts as «all-Russian nation», «ethnic identity», which are in the center of discussions in the scientific community. Granted the data of new ethno-sociological studies, the study attempts to further clarify the conceptual bases of these notions, the processes contributing to their formation, and their relationship with other forms of individuals’ identities and loyalties characteristic of modern Russian society. Conclusion. The process of growing national (federal) identity may encounter some difficulty, granted that there are problems in the economic sphere and everyday life. Positive changes in the economic, political, and social areas that will further a better quality of life and provide greater opportunities for development of human potentialities may significantly improve the situation. A diversity of ethnic, cultural, and confessional backgrounds characteristic of the populations in the regions in question contribute to the specific features of their worldviews, loyalties and perceptions, and the study of the mentalities of the people is of urgent relevance for the development of adequate policies in the area.
