The article is based on the study results of the role of labor migrants from the post-Soviet countries in meeting the needs of Russian households in different services. The aim of the work is to analyze the structure of national contingents and the specifics of the services provided by labor migrants from specific CIS countries. The author used statistical and sociological methods of data analysis and a comparative analysis of data from various statistical sources on the problems of labor migration in Russia. The empirical base of the study is the second sample survey in the Rosstat modern history "Results of sample statistical observation of migrant labor. 2019", and the comparison with official statistics. Along with the introduction of previously unused data from a large-scale study conducted by Rosstat into scientific circulation, the author reveals the specifics of the sectoral distribution of immigrants from nine post-Soviet countries. The author concludes that the significant concentration of labor migrants in a certain range of industries providing services to households (i.e., actually to the population) mainly includes construction and repairs, cleaning, various types of agricultural work and transport services. Employment in other sectors is less widespread, which largely correlates with the professional and qualification structure of labor migrants. National preferences for employment in certain sectors are also observed. The author analyses the features of hiring migrants both by households and by members of households as entrepreneurs. It was revealed that the latter attract a limited number of labor migrants, since they are, first of all, individual entrepreneurs representing small and microenterprises. The study results may be of further use to federal and regional executive bodies responsible for the development and implementation of state policy in the field of regulation of external labor migration flows, open up prospects for more reliable forecasting of the balance of supply and demand for foreign labor.
