Ethnodemographic processes among the Udmurts of the Kirov region during the Soviet period

Introduction. Historically, Russian society has developed as a multiethnic one, and today its composition is undergoing changes largely driven by assimilation processes. In this context, the topic of ethnodemography is relevant yet underexplored. For a long time in the USSR, demographic data were classified, and later it was revealed that existing sources contain information on ethnodemographic processes only for certain years, with incomplete records. Therefore, researchers need to utilize additional information sources and interdisciplinary studies, which may help fill existing statistical gaps. The aim of this study is to analyze demographic processes among the Udmurts of the Kirov region from its formation until the collapse of the USSR.
