AN INTRODUCTION TO THE BUSINESS LONGITUDINAL DATABASE
The BLD contains both business characteristics and financial information of small to medium businesses in Australia. It is an overlapping panel where the first wave of panel data was collected for the 2004-05 reference period and three years data are available. Australian Bureau of Statistics recently released its first wave of BLD data for public access.
Accessibility of BLD Data
The BLD is made available through a Confidentialised Unit Record File (CURF), which is released with the approval of the Australian Statistician. To ensure micro-data confidentiality is maintained, access is managed in a unique virtual environment, the Remote Access Data Laboratory (RADL). Further information is available at the CURF Microdata Entry Page on the ABS website.
The sample design involves the use of panels that represent the Australian business population at the point in time that each is initiated into the BLD. Panel One is representative of the in-scope business population as at 30 June 2005. Panel Two is representative of the in-scope business population as at 30 June 2006. Each Panel is directly surveyed once a year for a period of five years. In this current edition of the BLD CURF, Panel One contains three reference periods of data (2004-05, 2005-06 and 2006-07) and Panel Two contains two reference periods of data (2005-06 and 2006-07).
The Business Longitudinal Database 2004-05, 2005-06 and 2006-07 CURF is only available as an expanded CURF accessed via the RADL. The aim of the BLD is to produce a reliable longitudinal dataset of both characteristics and financial data that will allow analyses of changes in the performance of a cohort of small and medium businesses over time. The BLD is specifically designed for longitudinal purposes and not to produce accurate cross-sectional/population information.
Some of the key data items on the BLD CURF include:
