The presence of bathroom facilities, ascertained for all occupied and vacant housing units. This question was asked on a sample basis.
A room with a flush toilet, bathtub or shower, and a wash basin with piped hot and cold water for the exclusive use of the occupants of the housing unit. (Although the instructions on the questionnaire do not specify that a complete bathroom must have hot water, this requirement was applied during the processing of the data in the edit combining the items on complete bathrooms and complete plumbing facilities for the exclusive use of the household.) The equipment must be inside the unit being enumerated.
No bathroom or only a half-bathroom
A unit with no bathroom facilities, only a half bathroom, or bathroom facilities which are also for the use of the occupants of other housing units. A half bathroom has at least a flush toilet or a bathtub or shower for exclusive use but not all the facilities for a complete bathroom.
Data on number of bathrooms have been collected since 1960. The category "2 l/2 or 3 bathrooms" was included in 1970 but dropped for 1980.
