The Million Programme was a large public housing program implemented in Sweden between 1965 and 1974 by the governing Swedish Social Democratic Party to ensure the availability of affordable, high quality housing to all Swedish citizens. The program sought to construct one million new housing dwellings over a ten-year period, which it accomplished. As part of its intention to modernize Swedish housing, it also demolished many older buildings that national and local governments considered obsolescent, unhealthy or derelict.

Public housing is a form of housing tenure in which the property is usually owned by a government authority, either central or local. Although the common goal of public housing is to provide affordable housing, the details, terminology, definitions of poverty, and other criteria for allocation vary within different contexts. 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.
