Assessment of the Far East Regions Population Size Based on Territorial Changes Since 1939

The article examines the comparability of population census results across different years within the same territory, a challenge posed by changes in regional and municipal boundaries. The research focuses on recalculating population sizes within the Far Eastern Federal District (FEFD) using the boundaries established by the 2020 census. This analysis spans from the 1939 all-Union census onward, aiming to ensure demographic comparability across different periods by adjusting for changes in municipal structures from 1939 to 2020. In the course of this study, the authors have achieved the following outcomes, demonstrating scientific originality and novelty: 1. Developed and tested a methodology for recalculating population sizes in regions and municipal entities while considering changes in municipal structures. 2. For the first time, recalculated the population of the FEFD, covering all 11 constituent subjects and 230 municipal entities from 1939 to 2020, based on their current boundaries and accounting for territorial adjustments (derived from census data from 1939 to 2020). This method enables effective comparisons of population densities across various time periods. 3. Grouped FEFD regions and municipalities based on the mobility of their territorial boundaries, identifying stable, relatively stable, and unstable areas. The practical implications of this research are significant, as the findings can be used to assess actual population growth rates in FEFD territories. These results have potential applications in academic studies on the demography of the Far East, as well as in state and municipal governance related to the socio-economic development of these regions.
