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
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 for livestock slaughterings and wool is obtained from Australian Bureau of Statistics (ABS) collections. Price information for other commodities is obtained from non-ABS sources, including marketing authorities and industry sources.
For most years quantity data for crops and egg production have been collected via relevant Agricultural Surveys (AS) and Agricultural Censuses. For 2007-08 production quantity data for a more limited set of crop commodities have been sourced from a new Agricultural and Resource Management Survey (ARMS). Remaining commodity data are obtained from other ABS collections, with some information from external sources. The data are collected on a state basis and then aggregated to derive Australian totals.
TIMELINESS
Value of Agricultural Commodities Produced preliminary data are published 7 months after the reference period, and approximately 8 weeks after the publication of related agricultural production data in Principal Agricultural Commodities, Australia, Preliminary (ABS Cat. No. 7111.0).
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 and auctioneers. Production data is obtained from a range of high-quality sources, including ABS agricultural commodity collections and industry bodies. Extensive editing of this data and checking of resultant value estimates against earlier years and relevant other sources are used to ensure the accuracy of the estimates produced.
COHERENCE
Most data are directly comparable over different collection cycles.
INTERPRETABILITY
The survey provides a broad range of up-to-date data about the value of agricultural commodities produced in Australia through a suite of standard products or as data customised for individual requirements. Detailed explanatory notes are provided in Value of Principal Agricultural Commodities Produced , Australia, Preliminary (ABS Cat. No. 7501.0) to assist users in determining and specifying their data requirements and to understand the concepts underlying the data.
ACCESSIBILITY
An extensive range of data are available from the Value of Principal Agricultural Commodities Produced collection.
