1 This publication presents preliminary estimates of principal agricultural commodities and livestock numbers for the 2006-07 season, ewes expected to lamb in the forthcoming season, and comparative data for the previous year. The preliminary estimates are based on a response rate of 71% from the 2006-07 Agricultural Survey.
2 The estimates for 2005-06 are the third release of preliminary National and State level estimates for principal agricultural commodities and livestock numbers collected in the 2005-06 Agricultural Census. The estimates are based on a final response rate of 93% and implement the final methodology for handling non-response.
3 Final estimates for 2005-06 for the full range of commodities and to sub-state levels, including Natural Resource Management (NRM) regions and Statistical Local Areas (SLA), will be released in March 2008. The final estimates are not expected to differ significantly to the 2005-06 estimates in this publication.
SCOPE AND COVERAGE
4 Estimates in this publication are based on information obtained from the Agricultural Survey conducted at 30 June 2007.
5 The scope of the 2006-07 Agricultural Survey was essentially all agricultural businesses above a minimum size cut-off recorded on the Australian Business Register (ABR) maintained by the Australian Taxation Office (ATO).
6 For the 2006-07 Agricultural Survey, the measure of size was the ABS's Estimated Value of Agricultural Operations (EVAO) where available; or where it was not available a Business Activity Statement (BAS) turnover size was derived. A minimum size cut-off of $5,000, based on either EVAO or BAS Turnover, was used to determine whether a unit was in-scope for the Survey.
7 Where figures have been rounded, discrepancies may occur between sums of the component items and totals.
RELIABILITY OF ESTIMATES (SAMPLE ERROR)
8 The estimates in this publication are based on information obtained from a sample drawn from the total farm population in scope of the collection, and are subject to sampling variability; that is, they may differ from the figures that would have been produced if all farms had been included in the Agricultural Survey. One measure of the likely difference is given by the standard error (SE), which indicates the extent to which an estimate might vary by chance because only a sample was taken. There are about two chances in three that a 'sample' estimate will differ by less than one SE from the figure that would have been obtained if all farms had responded, and about nineteen chances in twenty that the difference will be less than two SEs.
9 In this publication, 'sampling' variability of the estimates is measured by the relative standard error (RSE) which is obtained by expressing the SE as a percentage of the estimate to which it refers.
10 Most published estimates have RSEs less than 5%. For some states with limited production of certain commodities, RSEs are greater than 10%. Estimates that have an estimated RSE between 10% and 25% are annotated with the symbol '^'. These estimates should be used with caution as they are subject to sampling variability too high for some purposes. Estimates with an RSE between 25% and 50% are annotated with the symbol '*', indicating that the estimate should be used with caution as it is subject to sampling error too high for most practical purposes. Estimates with an RSE greater than 50% are annotated with the symbol '**', indicating that the sampling variability causes the estimates to be considered too unreliable for general use. Separate indication of the RSEs of all estimates is available on request.
