The concentration of BSR population continues to a large extent.
Urban sprawl is re-shaping many large urban areas in the BSR.
Only ten urban regions swallow 47 % of all migration surplus in the BSR.
The summarised loss due to out-migration in the BSR amounts in five years to a region like the Republic of Karelia being totally deserted, whereas every 2½ years, housing, roads, schools, business facilities, public transport, etc. equalling a city the size of Stockholm needs to be performed somewhere in the BSR.
Data shows unequivocally that in the entire BSR, regions with acknowledged territorial handicaps (sparse, border, rural, peripheral) are suffering worst in terms of population drainage through migration.
Regarding migration, SMESTO regions however have as a group not been affected by the financial downturn of 2008 as much as other urban areas. The economic slowdown some times acts as a balancing force between core and periphery.
Europe is the primary reference point for global BSR migration. This concerns both emigration from and immigration to the region.
The BSR displays a substantial integrative trend in intra-BSR migration flows. More people migrate between BSR countries than to the rest of Europe.
Migration in the BSR does not aid in the achievement of the overarching horizontal EU goal of territorial cohesion. Migration appears to strengthen both the east-west and the north-south divides of the BSR.
Most indications point towards a strengthening also of the urban-rural divide.
BSR migration also appears to counter effect the achievement of most overarching EU 2020 strategy goals, albeit regarding specifically poverty reduction, it could also be argued to the contrary.
