The Housing and Land Survey is the most fundamental statistical survey on housing conditions conducted for the purpose of obtaining basic data for various policy measures on housing and land by investing actual situations and trends of dwellings and other occupied buildings and the inhabiting households for the whole country, major metropolitan areas, and prefectures. It had been conducted every five years since 1948 as Housing Survey until the tenth in 1993, then, the scope of survey was extended to include questions on land and the name was changed to Housing and Land Survey in 1998.The 2003 Survey is the twelfth in the series.
In the 2003 Survey, approximately one in four enumeration districts of the 2000 Population Census was sampled as the first stage, and then approximately 210,000 unit districts were randomly selected from the areas demarcated in the sample enumeration districts as of February 1, 2003. The survey was conducted through a channel of the Statistics Bureau, Ministry of Internal Affairs and Communications; prefectures; shi (cities), machi (towns) and mura (villages); and enumerators. Questionnaires were filled out by self-entry method (partly entered by enumerators).
The reference period is as of October 1.

Conditions (2) and (3) may be for join use, if they are in a location where they can be used at any time and can be accessed without passing through a floor of another household.
