Public housing, also known as social housing, is subsidized or affordable housing provided in buildings that are usually owned and managed by local government, central government, nonprofit organizations or a combination thereof. The details, terminology, definitions of poverty, and other criteria for allocation may vary within different contexts, but the right to rent such a home is generally rationed through some form of means-testing or through administrative measures of housing needs. One can regard social housing as a potential remedy for housing inequality. Within the OECD, social housing represents an average of 7% of national housing stock (2020), ranging from ~34% in the Netherlands to less than 1% in Colombia.
In the United States and Canada, public housing developments are classified as housing projects that are owned by a housing authority or a low-income (project-based voucher) property. PBV are a component of a public housing agency. PBVs, administered by state and local housing agencies, are distinct from Section 8 Project-Based Rental Assistance (PBRA), a program through which property owners' contract directly with the Department of Housing and Urban Development (HUD) to rent units to families with low incomes.
