About CURF Microdata
 

Confidentialised Unit Record Files (CURFs) are microdata files containing individual responses. These files have been treated to protect privacy and confidentiality using a range of statistical techniques. Some datasets provide access to ABS survey or census results while other datasets contain administrative data collected by other organisations. There are two types of CURFs:

Basic CURFs
The least detailed unit record data. Users can access basic CURF data in their own environment. Individual data items in basic CURFs are likely to be reported at a broader level than that offered in other ABS microdata products.

Expanded CURFs
Moderately detailed unit record data. Due to the protected environments in which expanded CURFs are accessed, users are able to access a finer levels of detail than that offered on a basic CURF. For example, where a basic CURFs might report an age classification in five-yearly increments, an expanded file may include data for each year. Access to expanded CURFs is provided in the secure Remote Access Data Laboratory (RADL) and the DataLab environments. To use these systems, users must be experienced in one of the analytical languages available.

Alternatively, the ABS may be able to produce customised CURFs to serve specific approved statistical purposes for a particular customer. The cost to produce a customised CURF is fully cost recovered from the customer. Customised CURFs may include data items and levels of detail not otherwise disseminated, or may be configured in other ways to respond to particular user needs. Production of Customised CURFs is dependent on availability of ABS resources. If you are interested in requesting the production of a Customised CURF email microdata.access@abs.gov.au.
