QUALITY DECLARATION - SUMMARY
INSTITUTIONAL ENVIRONMENT
For information on the institutional environment of the Australian Bureau of Statistics (ABS), including the legislative obligations of the ABS, financing and governance arrangements, and mechanisms for scrutiny of ABS operations, please see ABS Institutional Environment.
RELEVANCE
This publication contains preliminary estimates from the 2014-15 Value of Agricultural Commodities Produced (VACP) Collection. The value estimates in this publication are derived by the multiplication of price and quantity of agricultural commodities. Price data refer to the average unit value of a given commodity realised in the marketplace. Price information is obtained from ABS collections, as well as from non-ABS sources, including marketing authorities and industry sources.
Quantity data for crops has been collected via the 2014-15 Rural Environment and Agricultural Commodities Survey (REACS). Remaining commodity data are obtained from other ABS collections, with some information gathered from external sources. The data are collected on a state/territory basis and then aggregated to derive Australian totals.
Preliminary estimates from the 2014-15 Rural Environment and Agricultural Commodities Survey (REACS) will be presented in:
Principal Agricultural Commodities, Australia, Preliminary, 2014-15 (cat. no. 7111.0) which contains detailed statistics on principal crop area and production and livestock numbers. The publication presents data on a national, state and territory basis. Final estimates that also include sub-state level data will be released in Agricultural Commodities, Australia, 2014-15 (cat.no. 7121.0) in mid-2016.
TIMELINESS
Preliminary estimates from the VACP Collection will be published within 7 months of the reference period, and at the same time as the preliminary agricultural production estimates from the REACS which can be found in Principal Agricultural Commodities, Australia, Preliminary, 2014-15 (cat. no. 7111.0). Final estimates from the 2014-15 VACP Collection will be released in Value of Agricultural Commodities Produced, Australia, 2014-15 (cat no. 7503.0) from mid-2016.
Gross Value of Irrigated Agricultural Production (cat. no. 4610.0.55.008) will be published in late 2016.
ACCURACY
The accuracy of price data is ensured by the collection of price data from the best known sources. Where a statutory authority handles marketing of the whole or a portion of a product, data are usually obtained from this source. Information is also obtained from marketing reports, wholesalers, brokers, dealers and auctioneers. Production data are obtained from a range of high-quality sources, including ABS agricultural commodity collections and industry bodies. Extensive editing of production and prices data and checking of resultant value estimates against earlier years and other relevant sources are used to ensure the accuracy of the estimates produced.
All estimates in this publication are subject to sampling error. For more information about sampling error refer to the Explanatory Notes within this release.
COHERENCE
Most estimates in this publication are directly comparable to previous reference periods. However, estimates of 'Total crops', 'Total livestock slaughtering and other disposals' and 'Total agriculture' are not directly comparable to all previous issues due to changes data items that are included in these ‘total’ items.
INTERPRETABILITY
