This paper focuses on the problem of studying the demographic structure of the Irkutsk oblast in terms of reducing the number and proportion of young and working-age population. The indicators of reproduction of the population of the Irkutsk oblast for the period from 2011 to 2018 are analyzed. According to the UN scale, the proportion of elderly people over the age of 65 for the municipal districts, which determines the general pattern of aging of the population, is calculated. The cartograph ic method is used for grouping the territory of the Irkutsk oblast according to three types of age structures of the population: progressive, stationary, and regressive. It is shown that the demographic structure of the region’s population is territorially dif ferentiated: the progressive type is characteristic of the middle settlement area of the Irkutsk oblast and the Ust-Orda Buryat Ok rug, and the regressive type is characteristic for most urban districts and northern peripheral regions of the region. It is proposed to distinguish a transitional subtype from the progressive type of the age structure to the stationary type with a minimum difference in the proportion of ages younger and older than the working-age one. It has been established that the formulas for the age structures of the population of municipal districts are determined by the indicators of natural reproduction and the migration situation. According to state statistics, the forecast of the demographic structure of the population until 2036 is given. Currently, the region’s population is characterized by a transition from the stationary type of demographic structure to the regressive one.
