In the broad-base system, social housing is open to all citizens without necessarily applying any priority criterion in the allocation of dwellings. In targeted systems, social housing operates apart from the private rental market, and only households for which the market is deemed unable to deliver housing will benefit from it. Income thresholds or vulnerable groups could be criteria for eligibility in this system. Table 2.4 shows a comparison of types of social housing systems across OECD countries that may lead Kazakhstan’s leadership in its debate to define the best system for the country.
