This article explores the specifi city of the urbanization process in the native population of the Altai Republic and assesses its principal trends over the course of the years 1926–2020. The focus is on quantitative aspects such as the growth of urban settlements and their population. I look at the ways the urban network has developed in the Altai Mountains. The only urban administrative center shows a potential for agglomerative growth and continues to accumulate the rural population. Townships that had emerged during the Soviet period were unattractive for natives. Three stages in the urbanization process are described: 1926–1950s, 1960–1980s, and 1990 to the present. Over the entire period in question, urbanization was extensive, i.e. caused by migration from rural areas. At the fi rst stage, the key factor was political (collectivization). In the second stage, the factors were socio-cultural (attractiveness of urban lifestyle), economic (higher income and greater availability of jobs), and political (the abolition of “futureless” villages). The main factor at the third stage was socio-economic crisis. A conclusion is made that the potential for extensive urbanization in the native population of the Altai Republic has not yet been exhausted. The most attractive places to migrate are still the region’s capital and its suburbs. However, migration to other cities of Russia is likely to rise. A prediction is made that the role of intensive factors of urbanization in the indigenous population of the Altai Republic will increase.
