The age structure of the population of the regions of Russia at the beginning of the 21st century: components of the formation

In order to improve the management system of demographic processes, the article proposes and tests a non-standard methodology for studying the results of the demographic dynamics of the population of territories in the age context. The structure of their formation due to the main demographic components is disclosed. The main specific task is to assess as of mid-2021 for all regions of Russia - cumulative results of the demographic movement of the population accumulated over 28 years, which had an age of zero years in mid-1993. The proposed and tested methodology in the article allows us to clearly show the results of demographic dynamics and its components in a simple visual form. According to the current official Russian statistics, the demographic situation in the regions of Russia as of mid-2021, concerning the population aged 28 years, can be represented as follows (we will give two typical examples). Moscow: out of 100 persons aged 0 years, in mid-1993, 94 survived in 28 years (with zero migration). Migration increase added 107 people to them, including 87 at the expense of other Russian regions and 20 at the expense of foreign countries. Total: 201 persons out of 100 in 1993; Kurgan oblast: out of 100 persons aged 0 years in mid-1993, 93 survived in 28 years (with zero migration). 15 people left by migration, including 25 people to other Russian regions. But at the expense of foreign countries, 10 people were added. Total: 78 persons out of 100.
