Producing agriculture financial statistics using linked data
Business structure information was used to deal with these issues and ensure the maximum number of meaningful links were made.
Initial linking results are very encouraging and indicate that approximately 90 per cent of 2005-06 Agricultural Census records can be linked to 2005-06 BIT and BAS records. The other important point is that unlinked Agricultural Census records have roughly the same proportional distribution by state and commodity as the linked records providing confidence that bias in our results will be minimised. Imputation is currently being considered as the best option for dealing with the unlinked records.
The next phase of the feasibility study, which is currently underway, is to focus on a conceptual comparison of Tax Data and ABS Financial Data, to ensure that the linked data set can be used to measure the appropriate financial concepts. Generally speaking, the concepts align fairly well, however there are some slight differences in the definition of some individual data items. At present, the funders and other potential users of the estimates (e.g. ABARE, National Accounts Branch) are being consulted regarding the financial concepts that are being measured.
ABS staff have provided a presentation to DAFF outlining the project achievements to date which has generated considerable interest from staff within the funding body. The project also provides ongoing opportunities for the ABS. The current and ongoing consultation will ensure that any estimates derived from the linked data set will inform and support the information needs relating to agricultural statistics.
