In particular, post-Soviet transition countries have limited knowledge of informal settlements, because housing in the Soviet era was considered as a universal right, with the State providing housing and basic infrastructure free-of-charge and centrally. With the commodification of access to housing and facilities in these countries, residents have been experiencing degraded standards of living, which also now represent a great challenge for policymakers. This is why it is important to raise awareness and to develop a broad understanding of the phenomenon as well as to suggest possible solutions.
