With more than 20 million Australians completing the Census, the Australian Bureau of Statistics now faces the enormous task of turning the raw data you provided into information that will be used to help plan a better and brighter future for Australians.

Once your paper form has been collected, it is transported under secure arrangements to the Census Data Processing Centre (DPC) via road, rail or air. If you completed your form using eCensus, your responses were encrypted and transferred electronically to the DPC as soon as you pressed the ‘Submit’ button.

Upon arrival at the DPC, your paper form is scanned to allow it to be read and processed electronically using intelligent automatic coding technologies. The information is also checked using special processes to help detect any missing or inconsistent pieces of information. For example, a missing house or unit number or unrecognisable handwriting.


Processing is split into two stages. The first, simple topics such as age, sex and religion are processed. Most of this processing is done automatically.

The second stage processes the more complex topics such as industry, qualifications and occupation, which requires a great deal of manual processing to allocate codes to your unique responses.

Once every form and eCensus response has been processed, the information is turned into a file of coded records of each person, family and household counted in the 2011 Census. These files form the basis of all Census data. Any release of data does not allow for the identification of any individual or household.

Once your form is processed and no longer needed it is pulped and turned into recycled paper or cardboard. All eCensus responses and images of Census forms captured during processing are also securely destroyed.

Australia will get its first glimpse of the 2011 Census data in June 2012. Census data will be released in two stages with the second release planned for October 2012.
