—Intraregional migration in modern Russia plays a crucial role in the realization of people’s life plans and contributes to a change in the configuration of space. Every second registered resettlement within Russia occurs within federal subjects. However, apart from the general scale and role in changing the population size of individual municipalities, nothing is known about intraregional migration. The authors collected statistical information on long-term intraregional migration in 1265 municipalities of 39 federal subjects (51.4% of the country’s population) for 2017, which made it possible to form arrival, departure, and net migration matrices for each region. This made it possible to analyze population flows and redistribution in intraregional movements between regional centers, suburban municipalities, and the regional periphery. The analysis revealed that the quantitative parameters of redistribution of the population between centers, their suburbs and other municipalities in all intraregional migration approximately correspond to their share in the population, and all classes of municipalities are equally involved in migration. There is intensive migration exchange between regional centers and their suburbs. The centers are not only inferior to the suburbs in terms of the intensity of migration growth, 80% of the centers are losing population in the migration exchange with their own suburbs. In general, the redistribution of the population in intraregional migration in almost all studied federal subjects contributes to an increased concentration of population in the agglomeration zone formed by regional center and its suburbs. In some federal subjects, another zone of population congestion, as a rule, of a much smaller size, are subcenters, represented by large cities a considerable distance from the regional center. They form their own migration gravity zones from the nearest peripheral municipalities. In most cases, this migration only allows subcenters to compensate for migration outflow to other regions or to their regional center.
