Three decades have passed since the collapse of the USSR. At the same time, in all post-Soviet states, already in the first decade, there was a landslide destruction of the production and scientific and technological potential, and the socio-economic situation deteriorated dramatically. Degradation processes have been most destructive in Ukraine, Georgia and the Republic of Moldova. This was largely a consequence of the disintegration of these states as a result of the so far unsettled armed confrontations with part of their territorial entities, as well as permanent political instability in general. The study is developed within the State Program (2020-2023) 20.80009.0807.21 “Migration, demographic change and stabilization policies”.
