Dynamics and Migration Concentration of the Population of the Trans-Siberian Corridor in Baikal Siberia

The purpose of this study is to identify the spatial dynamics of the population of the territories of the south of Baikal Siberia (Irkutsk region, Republic of Buryatia and Trans-Baikal Territory). The study was conducted using statistical, cartographic and comparative geographical methods; The units of statistical observation are urban districts and municipal areas. The main results are the identification of the main urbanized areas and transport corridors in places of maximum population concentration. Thus, the demographic potential of the Irkutsk part of the Trans-Siberian transport corridor accounts for more than half of the region’s population. The influence of the level of development and location of productive forces on the demographic situation and the transformation of settlement systems is assessed. Geographical aspects of spatial development are expressed in the strengthening of two partially overlapping gradients of population and production concentration: mainline-peripheral and central-peripheral. Currently, agglomeration effects prevail over highways, but all agglomerations operate on highways. Modern market conditions, through increased economic contrasts, the strengthening of the role of the most important highways and agglomerations, and the degradation of local infrastructure, affect the demographic situation.
