Dynamics of ethnocontact zones in the Turkic republics of the Ural-Volga region in the post-Soviet period

Introduction. The interest of world science in assessing the ethnic diversity of countries and regions predetermines the development of the concept of ethnocontact zones. To test new methods within the framework of the concept, there is a need to conduct research not only at the regional, but also at the intraregional levels. The purpose of the study is to classify the municipalities of Chuvashia, Tatarstan and Bashkortostan according to ethnic dynamics in the post-Soviet period using the methodology developed by the authors in accordance with the concept of ethno-contact zones.
