The emergence of new state borders in the formerSoviet Unionhas led not only to geopolitical changes, but also to significant changes in the economic, ethnic and other situations in the surrounding areas. This fully applies to the Russian-Kazakhstan transboundary region, which over the past three centuries evolved as a unified whole, representing a conjoint historicalgeographical, ethnic and economic space, though complex in structure. At present the territory of the cross-border region is a testing ground, where the concept of Eurasian cooperation, covering various aspects of socio-economic and ethno-cultural interaction is being tested. All this gives grounds for a more detailed consideration of the Russian-Kazakh integration process, which is one of the most effective and successful forms of Eurasian cooperation in the postSoviet space. A study of the current status of the population in the borderland allows one to assess the prospects of demographic processes on both sides of the state border, and the geopolitical consequences of the dynamics of changes in population.
