The aim of Business Longitudinal Database (BLD) is to facilitate micro level analysis for a panel (cohort) of small and medium businesses over time, and it includes both characteristics and financial data. The BLD Confidentialised Unit Record File (CURF) provides information for the first two panels included in the BLD. Panel One contains three reference periods of data (2004-05, 2005-06 and 2006-07) and Panel Two contains two reference period of data (2005-06 and 2006-07).

The BLD CURF is available via the Australian Bureau of Statistics (ABS) Remote Access Data Laboratory (RADL). The RADL is accessible for authorised users via the ABS web site. Users should refer to the CURF Microdata entry page (
www.abs.gov.au, Services, CURF Microdata).

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.

This Technical Manual provides comprehensive information for BLD CURF users.
