Marriage structure of the population of Udmurtia in 1989-2021

Introduction. The article presents, for the first time, a historical and demographic study of the marital status of the population of Udmurtia from 1989 to 2021. The relevance of the topic is due to its insufficient study and the need to understand the reasons behind the sharp decline in the Udmurt population over the last two inter-census periods. The aim of the research is to identify the characteristics of changes in the marital structure of the Udmurt population in the Udmurt Republic during the period from 1989 to 2021.
