1 This publication contains final estimates for the main commodities collected in the 2002-03 Agricultural Survey and related Supplementary Collections (i.e. Apples and Pears Collection and Vineyards Collection). It contains detailed statistics on crops, livestock and livestock products and characteristics of farms.
SCOPE AND COVERAGE
2 Estimates of farm production are based on information obtained from the Agricultural Survey conducted at 30 June 2003. Prior to 1999-2000 information was obtained for the period ending 31 March. The ABS has changed the collection period to 30 June to better align with other ABS surveys. A study of respondent data indicated that there should be no significant difference in estimates collected between the reference periods.
3 The scope of the 2002-03 Agricultural Survey is establishments undertaking agricultural activity with an estimated value of agricultural operations (EVAO) of $5,000 or more. This is the same as the scope for Agricultural Censuses from 1993-94 to 1996-97 and for 2000-01 and the 1997-98, 1998-99, 1999-2000 and 2001-02 Agricultural Surveys. Prior to 1993-94 scope has varied and these details are available on request.
4 From 2005-06 the ABS will use the Australian Business Register as the main source of frames for its agricultural surveys. Until then, the Agriculture Survey sample will be selected from the 2001-02 survey frame.
5 For the 2001-02 Agriculture Survey, a stratified random sample of 35,000 farms was selected. For the 2002-03 Agriculture Survey, a sub-sample of 28,000 units from the 2001-02 selections was used. This helped control the estimates of movement for that year which was particularly important given the impact of the drought.
6 The sample for the 2003-04 Agriculture Survey will be the same 28,000 selected for the 2002-03 survey. A further 3,000 units will be selected to cover sample loss due to units in the original selections having ceased farming, and to improve relative standard errors where commodities were approaching or exceeding design parameters in the 2002-03 Agricultural Survey. A proportion of the 3,000 units will also be used to sample units that have commenced farming since 2001-02. This strategy will again help ensure good estimates of movement as parts of Australia move out of the drought.
7 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.
8 Since 1991-92, units in the Agricultural Census and the Agricultural Survey have been classified according to the methodology described in Australian and New Zealand Standard Industrial Classification (ANZSIC) (cat. no. 1292.0). Prior to 1991-92, establishments were classified according to the methodology described in the 1983 edition of Australian Standard Industrial Classification (ASIC), Volume 1 - The Classification (cat. no. 1201.0). Therefore care should be taken when making comparisons between years where different classifications have been used.
9 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.
10 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.
11 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 relative standard error 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 variability 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.
RELATIVE STANDARD ERROR OF SELECTED COMMODITIES - As at 30 June 2003
CROPS, PASTURES AND HORTICULTURE
12 Statistics on area and production of crops relate, in the main, to crops sown during the year ended 30 June. Statistics of perennial crops relate to the position at 30 June and the production during the year ended on that date, or fruit set by that date. Statistics for apples and pears and grapes, which in some states are harvested after 30 June, are collected by supplementary collection forms and are included in this publication.
13 A number of vegetables collected in previous years were not collected separately in 2002-03. These include beetroot, cabbages, celery, cucumbers, marrows, squashes, zucchini, parsnips and sweet corn. Please contact the ABS if you require details of other vegetables not collected in 2002-03.
LIVESTOCK SLAUGHTERING AND LIVESTOCK PRODUCTS
14 The statistics on livestock slaughtering and meat production are based on data collected from abattoirs and other major slaughtering establishments and include estimates of animals slaughtered on farms and by country butchers and other small slaughtering establishments. Care should be taken when using this information as the figures only relate to slaughtering for human consumption and do not include animals condemned or those killed for boiling down. Definitions of livestock categories may differ between states and within states, particularly with regard to calves.
15 Wool production statistics contained in this publication are derived from the quarterly ABS Wool Brokers and Dealers Receivals Collection and are published on the basis of state of production.
16 Wool receivals statistics show the amount of taxable wool received by brokers and dealers from wool producers. It excludes wool received by brokers on which wool tax has already been paid by other dealers (private buyers) or brokers.
17 Milk statistics have been collected and provided to the ABS by Dairy Australia. Data for the Australian Capital Territory are included with New South Wales; data for the Northern Territory are included with South Australia.
18 Poultry slaughtering statistics have been compiled from quarterly returns supplied by commercial poultry slaughtering establishments. Producers in Tasmania, the Northern Territory and the Australian Capital Territory are not included in the aggregates derived from the Poultry and Game Birds Slaughtered collection. However, the statistics represent a high level of coverage.
ABS DATA AVAILABLE ON REQUEST
19 As well as the statistics included in this and related publications the ABS may have other relevant data available on request. Inquiries should be made to either the National Information and Referral Service on 1300 135 070 or Gordon Cameron on (03) 6222 5939.

Their continued cooperation is very much appreciated: without it, the wide range of statistics published by the ABS would not be available.
