ABOUT THE CURF

The data included in the 2012 Labour Force Survey (LFS) and Labour Mobility Survey, Basic and Expanded CURFs are released under the provisions of the Census and Statistics Act 1905. This legislation allows the Australian Statistician to release unit record data, or microdata, provided this is done “in a manner that is not likely to enable the identification of a particular person or organisation to which it relates.”

The ABS ensures the confidentiality of the data by:

  • removing name, address and any other information that might uniquely identify any individual
  • changing a small number of values - particularly unusual values - and removing very unusual records
  • controlling the detail available for all records on the Basic and Expanded CURF
  • excluding some data items that were collected
  • controlling the modes of access to restrict access to more detailed data
  • placing restrictions on how the data are used, supported by both information in the User Manual: Responsible Use of ABS CURFs, the undertaking signed by the head of each organisation and the terms and conditions signed by each user.

As a result, data on the Basic and Expanded CURFs will not exactly match other previously published estimates. Any changes to the distribution of values are not significant and the statistical validity of aggregate data is not affected.
