Today, the human migration is one of the most important factors in the socio-economic territorial development. This process requires considerable attention on the part of federal, regional and municipal general government. The main trends that characterize migration in Russia at the present time is a population tightening and a high level of its concentration in the European part of the country, a significant outflow of population from towns, small cities, as well as rural settlements, migration inflow to large and highly developed territories, an increase in the socio-economic development polarization in territories, etc. These problems are also considered in the Concept of the State Migration Policy in the Russian Federation for 2019-2025. At the same time, despite the adoption of the Concept several issues remain unresolved, such as the lack of state attention to internal Russian migration, the definition of specific needs of the region and municipalities, as well as the lack of a quantitative assessment of targets, etc. It is necessary to clarify the main directions and mechanisms for implementing Russia's migration policy. It is promising to consider population migration from the point of view of meeting the various interests and needs of the main participants in this process - a person, business, territory (locality, region, country), in our opinion. An essential point in the development of such a mechanism is an adequate and scientifically based description of the characteristics of each agent., It is necessary to develop a set of proposals for improving the migration policy and measures for its implementation to achieve a balance of interests of these agents.
