From the late 1940s on Vilnius began to grow again, following an influx of Lithuanians, Poles and Belarusians from neighbouring regions and throughout Lithuania as well as neighbouring region of Grodno and from other more remote areas of the Soviet Union (particularly Russia, Belarus and Ukraine). Most of these new residents moved to Vilnius, due to repressions or poor living conditions caused by, e.g. collectivisation, in areas, where they lived previously. On the previously rural outskirts as well as in the very vicinity of the Old Town (industrial zones in Paupys, Markučiai, Naujamiestis), industrial areas were (re)designed and large Soviet plants were built, following a program of industrialization.
