Peculiarities of population migration in Russian regions border Belarus

The article shows the demographic development of the Bryansk, Pskov, and Smolensk regions bordering Belarus in all the post-war years, to what extent it was caused by the consequences of the Great Patriotic War (many days of bloody battles, the destruction of civilians by punitive forces during the years of occupation, as well as the evacuation of part of the population). It was revealed that the share of the three regions bordering Belarus after the war significantly decreased in the population of Russia. It was also established that another factor in this dynamics was the migration outflow of the population. The article discusses that over the past time there has been an increase in migration exchange with the capital cities, the significance of migration links with the northern regions has changed while maintaining their importance with those regions that are in the same federal district. It is shown that in international migration the IMR values largely depend on the proximity of the states of the new abroad from the regions of resettlement. It was revealed that among the countries with which Russia and all regions bordering Belarus had the most effective ties are Kazakhstan and Georgia. The most effective exchange was also with Latvia, Turkmenistan, and Tajikistan, while the least effective migration exchange in the considered regions was with Belarus and Ukraine, as well as Lithuania and Moldova.
