EXPLANATORY NOTES
SCOPE AND COVERAGE
1 Estimates of 2000-01 farm production were based on information obtained from the Agricultural Census conducted at 30 June 2001. The scope of the 2000-01 Agricultural Census was establishments undertaking agricultural activity with an Estimated Value of Agricultural Operations (EVAO) of $5,000 or more.
2 Statistics on area and production of crops relate in the main to crops sown during the year ended 30 June 2001. Statistics of perennial crops and livestock relate to the position as at 30 June 2001 and the production during the year ended on that date, or of fruit set by that date. Statistics for apples and pears and for grapes, which in some states are harvested after 30 June, are collected by supplementary collection forms and are included in this publication.
AGRICULTURAL ESTABLISHMENTS
3 An agricultural establishment is the smallest accounting unit of business within a state or territory controlling its productive activities and maintaining a specified range of detailed data enabling value added to be calculated. In general, an establishment covers all operations at a physical location, but may consist of a group of locations provided they are within the same Statistical Local Area (SLA) or contiguous SLAs. The majority of establishments operate at one location only.
NULL VALUES
4 Values of zero within the spreadsheets, have the annotation 'nil or rounded to zero (including null cells)' and may indicate that the estimate is very small and has been rounded to zero, that no respondents have reported producing the particular commodity in that region or that, in the case of commodities with an area estimate but production of zero, there has been a crop failure. Blank cells have the annotation 'n.p.', the abbreviation for 'not published'. This indicates that the data are unavailable in order to protect the confidentiality of a respondent(s).
ACCURACY
5 The estimates in this publication are based on information obtained from respondents to the 2000-01 Agricultural Census. Since not all selected units responded, the estimates may differ from those that would have been produced if all farms had responded. 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 when not all units have responded, i.e. when a 'sample' of responses only is obtained. 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.
6 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. Annotations on the cells provide the range within which the RSE of the estimate falls. No annotation denotes estimates with RSEs of less than 10%.
