INTRODUCTION
ABOUT THE CURF
This product provides information about the release of microdata sample files from the 2011 Census of Population and Housing. Included are details about the methodology, how to use the the sample files, and the conditions of use. Data item lists and information on the quality of the microdata are also provided.
Microdata are the most detailed information available from a Census and are generally the responses to individual questions on the Census Form or data derived from two or more questions. This level of detail is released with the approval of the Australian Statistician.
ABOUT THE MICRODATA
The 2011 Census Sample Files (CSFs) are confidentialised Unit Record Files (CURFs) of Census variables. They contain a small random sample of unidentified occupied private dwellings with their associated family and person records, and a random sample of persons from all non-private dwellings together with a record for the associated non-private dwelling. Subject to the limitations of sample size and the data classifications used, the CURF will enable users to tabulate, manipulate and analyse data to their own specifications.
The 1% Basic CURF contains data on 87,798 dwellings, 93,002 families and 215,597 persons. The 5% Expanded CURF contains data on 422,725 dwellings, 450,038 families and 1,083,585 persons.
The data were collected on Census Night, 9 August 2011.
