Abstract
The article examines the specifics of demographic processes in the Irkutsk agglomeration against the background of the regional situation. In the context of the theories of the second demographic transition and the second stage of the epidemiological transition, authors analyze the features of fertility and mortality in large and small cities and the suburbanized zone of the agglomeration. Based on the features of the age composition of fertility and mortality, the authors show the existence of three types of population reproduction in the onesomes space of the agglomeration: in a small town, large cities and suburbia. The first type was formed during the period of mass Soviet urbanization in the mid-20th century, the second - at the turn of the 21st century as part of the second demographic transition. The latter combines two oppositely processes: a decrease in mortality and an increase in life expectancy as part of the second stage of the epidemiological transition and an increase in the birth rate of migrants from the city while maintaining in general its urban age structure.
