Methodology for assessing demographic factors of the quality of life of the population of Russian regions based on the index of the viability of society

The methodology for assessing demographic factors of quality of life based on the community vitality index is an important tool for assessing the demographic situation and its impact on the sustainability of regional development. The article presents the methodology for constructing the index and its calculation. The Society Vitality Index is calculated for the constituent entities of the Russian Federation for 2020 and 2021. The methodology for calculating the society vitality index takes into account: life expectancy level, birth rate, average age of the population, as well as indirect indicators from the Federal Statistical Work Plan of the Russian Federation. The results obtained made it possible to identify clusters of Russian regions with low indicators of the social vitality index and to identify the relationship with the influence of negative environmental factors. Based on the construction and analysis of the index, recommendations are presented, which consist in using the index to monitor and identify problem areas in spatial development, taking into account a comprehensive assessment of the demographic situation, as well as in developing effective measures to improve the vitality of society and predict demographic changes.
