CONFIDENTIALISED UNIT RECORD FILES (CURFS)
What is a CURF?
A Confidentialised Unit Record File is a file of responses to an ABS survey that has had specific identifying information about a person or organisation confidentialised. Each person's or organisation's response to a survey is called a unit recordor microdata.The ABS ensures the confidentiality of all microdata made available on CURFs. This includes removing all identifying information, including names and addresses. Data items that are most likely to be used for identifying unit records are only released in broad categories. The files are also checked for any records with very unusual responses and these records may be altered slightly to ensure individuals cannot be identified. After the microdata is confidentialised, CURFs are released to authorised clients for approved purposes of statistical analysis and policy research.
Who uses a CURF?
CURF microdata is the most detailed statistical information available from the ABS. CURFs are used widely by universities, government and private sector researchers and analysts. A list of those who currently have access, together with their appointed contact officer, are available on the ABS website, under the Services We Provide heading.
Researchers and analysts are able to run statistical queries on the CURF microdata using SAS, SPSS or Stata software.
