“…Among the factors affecting the residential structure across BSR are the significant changes in the demographic profile (Berzins and Zvidrins, 2011;Hanell, 2000;Manakov et al, 2017;Michalski, 2001), the shift in the economy structure of the post-Soviet space (Glinkina and Kulikova, 2016;Kuznetsova, 2013;Sluka and Ivanov, 2014;Ubarevičienė and Burneika, 2015), and the coastal location of individual countries and regions. The coastal urban settlements of the BSR have become a particular subject for classification and analysis (Fedorov et al, 2017;Borodina, 2016;Enyedi, 1996;Lachininsky and Semenova, 2015), including the ones based on the level of metropolization (Druzhinin, 2014) and transnational cooperation (Palmowski and Tarkowski 2018;Bussmann and Nickel, 2018;Heininen, 2017;Pikner, 2008). Regional and local differences in population dynamics of coastal territories illustrate the centreperiphery gradients within the BSR, indicating the discreteness of its economic and socio-cultural space.…”
