The Census provides the characteristics of the population and its housing to support the planning, administration and policy development activities of governments, businesses, communities, researchers and other users. While some of this information is available from other sources, only a Census can provide the information for the country as a whole and for small geographic areas and small population groups.

Examples of how Census data are used can be found in the publication How Australia Takes a Census, 2011 (cat. no. 2903.0).

The 2011 Census Dictionary (cat. no. 2901.0) contains details of the classifications used in the 2011 Census along with definitions of Census concepts and terms. The dictionary is a comprehensive reference guide that will help you determine and specify your data requirements.
