Public housing

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.

Affordable housing goals can also be achieved through subsidies. Subsidized housing is owned and operated by private owners who receive subsidies in exchange for providing affordable housing. Owners may be individual landlords or for-profit or nonprofit corporations.

Social housing had existed sporadically prior to modern developments. The oldest still in use is the 16th-century Fuggerei in Augsburg, Bavaria.

The origins of modern municipal housing lie in the dramatic urban population increase caused by the Industrial Revolution of the 19th century. In the large cities of the period, many social commentators, such as Octavia Hill and Charles Booth reported on the squalor, sickness and immorality that arose. Henry Mayhew, visiting Bethnal Green, wrote in The Morning Chronicle:

... roads were unmade, often mere alleys, houses small and without foundations, subdivided and often around unpaved courts. An almost total lack of drainage and sewerage was made worse by the ponds formed by the excavation of brickearth. Pigs and cows in back yards, noxious trades like boiling tripe, melting tallow, or preparing cat's meat, and slaughter houses, dustheaps, and "lakes of putrefying night soil" added to the filth.

Some philanthropists began to provide housing in tenement blocks, and some factory owners built entire villages for their workers, such as Saltaire in 1853 and Port Sunlight in 1888. It was in 1885, after the report from a royal commission in England, that the state first took an interest. This led to the Housing of the Working Classes Act of 1885, which empowered Local Government Boards to shut down unhealthy properties and encouraged them to improve the housing in their areas.

The City of London Corporation built tenements in the Farringdon Road in 1865. The world's first large-scale housing project was built in London to replace one of the capital's most notorious slums – the Old Nichol. Nearly 6,000 individuals were crammed into the packed streets, where one child in four died before his or her first birthday. Arthur Morrison wrote the influential A Child of the Jago, an account of the life of a child in the slum, which sparked a public outcry. Construction of the Boundary Estate was begun in 1890 by the Metropolitan Board of Works and completed by the then-recently formed London County Council in 1900.
