The state of housing in a country has a direct impact on the level of public health, on the crime rate, and on many other social problems of importance. It also has an indirect effect on labor productivity in the economy through the general morale of workers. Practically all countries today are facing housing problems in varying degrees, especially in urban areas. For an underdeveloped country, its ability to provide adequate housing in urban areas is a vital prerequisite for successful industrialization. In countries which are relatively well developed, the rising income level of the population creates a constantly increasing demand for better dwellings.
