[Regional differentiation of demographic dynamics in Russia and the role of healthcare].

The article examines the role of the processes of natural and migration movement of the population in changing the total population of the regions of Russia for more than two decades of the XXI century. Six possible combinations of these processes are proposed, which result in either an overall increase in the population or a reduction. During the period under review, various scenarios in a number of regions had fairly stable trends - a constant decline in the population or a stable increase in it. Moreover, such stability was determined either by a stable natural increase exceeding the migration decline, or by a stable decrease in the population as a result of a stable natural decline or migration outflow. But many regions experienced both the turbulence of reproduction and migration processes, as a result of which the overall result for population dynamics also changed. For the first time, a typology of Russian regions was carried out according to the frequency of the influence of natural and migration growth on the total population of the regions. This allowed further studies to consider the role of migration processes on the demographic aging of the population of the regions.
