The United Nations Statistics Division is responsible for collecting official national statistics on housing stock and housing conditions generated from population and housing censuses. In 2005 the United Nations Statistics Division initiated a systematic and regular collection of basic statistics on housing by introducing a housing statistics questionnaire in the existing Demographic Yearbook data collection system.

Earlier data collections were conducted in 1992 and 1999, in collaboration with the United Nations Human Settlements Programme (UN-HABITAT).

Results of the data collection on housing statistics are available online.

The most recent technical reports review the collection and dissemination of data on household characteristics, living arrangements and homeless households within the Demographic Yearbook.
