The Basic and Expanded Confidentialised Unit Record File (CURF) contains data from both the monthly Labour Force Survey and the related Labour Mobility supplementary survey.
The Labour Mobility data is in relation to people aged 15 years and over who had worked at some time during the year ending February 2010. In addition to the standard labour force data items, the Labour Mobility data provides details of changes in jobs between employers/businesses for up to three jobs and, for those people who have been with their employer/business for the last 12 months, the changes in their job including promotion, transfer, changes in occupation and usual hours worked. Estimates can be cross-classified by demographics such as state, sex, age, marital status and country of birth, as well as labour force characteristics.
The Basic CURF is available on CD-ROM and users are able to tabulate, manipulate and analyse data to their individual specifications.
The EXPANDED CURF is available via RADL only. The RADL is accessible for authorised users via the ABS web site and enables the ABS to make more detailed microdata available than on CD-ROM, while still maintaining the confidentiality of ABS data providers.
Steps to confidentialise the dataset are taken to ensure the integrity of data, optimise its content and maintain confidentiality of respondents. They include removing any information that might uniquely identify an individual, reducing the level of detail for some items and collapsing some categories.
