This publication provides a range of information about the release of microdata from the Business Longitudinal Database (BLD). Microdata are the most detailed information available from a survey and are generally the responses to individual questions on the questionnaire. The microdata is made available through an Expanded Confidentialised Unit Record File (CURF) released with the approval of the Australian Statistician. The CURF is accessible through the Australian Bureau of Statistics (ABS) DataLab.

This publication includes details about the survey methodology and how to use the microdata. It also includes a data item list, a test file, definitions of common terminology used, and information on the quality of the microdata.


An Expanded CURF is available via the DataLab. Expanded CURFs allow approved users to query the data via statistical languages.
