The priority of state policy of the Russian Federation is to make conditions for sustainable social economic development of national regions, including the territories of the Arctic Zone. The successful solution of these tasks is possible only if there is sufficient amount of labor resources and at achieving positive dynamics of main demographic processes. The purpose of the study is to establish characteristics of both dynamics of main demographic processes and reproductive health of Northerners as exemplified by the Republic of Komi. Materials and methods. The retrospective ecological epidemiological study was carried out using reports of the Federal statistical observation. To evaluate demographic processes the values of main demographic parameters were calculated. To analyze dynamics of demographic processes time series of demographic coefficients were constructed and values of growth rate indicators were calculated. Results. The number of male and female population of the Komi Republic in 1990–2023 decreased by 46.5% and 37.1%. The specific weight of people older than able-bodied age increased in males from 4.9% to 14.7% and in females from 15.7% to 31.6%. The number of females of fertile age (16–49 years) in the Komi Republic decreased by 152.602 people (−47.5%) and their general fertility rate decreased by 33.3%. The birth rate in the group of young women aged 15–19 years decreased in 1990–2021 by 80.1%; and of women aged 20–24 years decreased by 60.4%. The frequency of abortions tends to decrease, but significantly exceeds the national average values. Conclusion. The replacement-level fertility is not achieved in the Komi Republic. Taking into account the peculiarities of demographic, social economic processes, it is necessary to develop and to implement regional program of reproductive health improvement.
