A question on the number of rooms/bedrooms has been included in every Australian Census since 1911, however the question relating to Number of Bedrooms in Private Dwelling was first asked for the 1976 Census.
While the 1986 Census Household Form asked householders to indicate the numbers of various room types, only the number of bedrooms was retained in the computer record.
The 1991 and 1996 Censuses collected data on the number of bedrooms only.
Since the 2001 Census, respondents have been asked to write in the number of bedrooms in their dwelling rather than mark a response category. An additional 'None' mark box was added in 2006.
This variable was unchanged between 2011 and 2016.
Item non-response rates are a measure of how many households did not respond to a particular question as a proportion of the total number of households the question was applicable to. In this instance the response is left as not stated.
The majority of item non-response is attributable to the households who did not respond to the Census at all. Refer to item non-response tables for more information. The second and smaller contributor to item non-response is when households return a Census form but may not answer a particular question(s). For more information, refer to Understanding Census data quality.
The non-response rate for Number of Bedrooms in Private Dwelling was 7.4% (5.4% in 2011).
Data usage notes
Dwellings with a high number of bedrooms reported were checked manually to ensure that they match the actual response on the form. The data may include a small proportion of dwellings with unusually large numbers of bedrooms, as all numeric responses are accepted as reported.
