Most families in Thailand live in dwellings that compare favorably with living facilities anywhere in Southeast Asia. The Thai government has stimulated housing and community development by means of a housing plan that provides government mortgages for building, renovation, or purchase of government land and houses. Under a self-help settlement scheme, the government sets up whole new communities, surveys sites, constructs roads and irrigation systems, and provides public utilities and medical care.
In 1973, to house Bangkok residents who had been living in makeshift shelters, the government formed the National Housing Authority (NHA), which undertook overall responsibility for coordination of public and private housing programs. By 1979, the NHA had completed 54,780 housing units. From 1979 to 1984, a total of 1,442,250 housing units were built in Thailand.
According to the preliminary results of the 2000 census, there were about 15,662,300 households nationwide. The average household had 3.9 people. About 79.7% of all households lived in detached houses. About 81.6% of all households were in owned dwellings.
