Completed Census forms are delivered to the Data Processing Centre (DPC) as soon as possible after Census Night. They are then put through a number of processes.
The first processing stage in the 2011 Census is precapture. During this process forms are checked to ensure key fields have been completed and extraneous material removed. The forms are then prepared for data capture.
The data capture stage is the second stage of input processing. This stage encompasses a number of processes, including:
The fourth stage includes Automatic Coding and Computer Assisted Coding (CAC). All hand-written textual responses are examined automatically to see if a classification code can be allocated based on the response provided. Where a classification code cannot be allocated automatically, CAC is used to allocate the classification code.
Quality control checks are constantly made for coding accuracy. The editing process is largely automatic, with some fields being reset based on other responses on the individual Census forms. All Census data are extensively validated before data are released.
