The Housing Survey is one of the main INSEE surveys in terms of its seniority (1955) and sample size (43,000 dwellings in 2006). It is the major statistical source for describing housing stocks and the conditions under which households occupy their main residence. It also serves to measure the housing costs borne by different types of households.
The 2006 survey benefited from regional and national partnerships serving to complete the national sample (extension into sensitive urban zones, extensions into six mainland regions and into the Overseas Departments).
