Frequently Asked Questions - About CURFs - How is CURF data 'confidentialised'?
 

Confidentialised Unit Record Files (CURFs) are files from which all identifiers have been removed. Identifiers may include details such as names and addresses. In addition, it is generally necessary for the ABS to alter the records to prevent the identification of survey participants who have a rare mix of responses. All CURFs are thoroughly checked to ensure data has been confidentialised prior to their release.

For more information, see 'Avoiding Inadvertent Disclosure' and 'Microdata' on the ABS web page How the ABS keeps your information confidential and the National Statistical Service Confidentiality Information Sheets. These sheets explain and provide advice on a range of issues around confidentialising data.
