Quality Framework This data quality framework has been published internationally (Brackstone G., Managing Data Quality in a Statistical Agency, (1999) Survey Methodology, Vol. 25, no. 2, Statistics Canada) and has been recommended by the ANAO as 'better practice' in specifying performance measures (ATO Performance Reporting under the Outcomes and Outputs Framework, Australian Taxation Office, Audit Report No.46 2000-01, pp63-64.) on advice from the ABS Statistical Consultancy Unit.

Why do you need to conduct a survey? (B1)
The prime objective of the Agricultural Survey is to act as a source of basic agricultural statistics about a wide variety of commodities. The Agricultural Survey is designed primarily to collect data about commodities (including area and production for crops, number of livestock and area irrigated). Data are also available on the number of producers for each commodity, and on the counts of producers by Australian and New Zealand Standard Industrial Classification (ANZSIC) class. The Agricultural Survey is also the major source of commodity data input into the calculation of Value of Agricultural Commodities Produced (VACP). VACP is a major output from the survey which is in turn used as an input to the Australian National Accounts. In addition to the core set of questions the 2006-07 Agricultural Survey contains both internally and externally funded non core questions. The internally funded questions relate to water usage. These questions are being funded by the Environment and Energy Business Statistics Centre. For 2006-07 there will be only one externally user-funded question. This will collect data on new and/or emerging vegetable varieties and several main stream varieties that are not normally collected by the ABS.
The 2006-07 Agricultural Survey will collect data for a wide range of agricultural commodities and land uses including: Area of holding; Area of holding by landuse; Hay and silage (area and production); Cereal crops (area and production); Other non-cereal crops (including cotton, sugar cane) (area and production); Nurseries, cut flowers and cultivated turf (area); Vegetables harvested for human consumption and for seed (area and production); Fruit and nut trees, plantation and/or berry fruit (tree number or area and production); Cattle, sheep, pigs, poultry and other livestock numbers; and Water use (area and crops irrigated and sources of irrigation water). Estimates: Final estimates are expected to be available at National, State and Statistical Division (SD). Data will be available by Estimated Value of Agricultural Operations, ANZSIC 06 and the previous ANZSIC 93, plus commodity and specified size ranges (e.g. area of holding size, herd size). Statistical unit: Data are collected at the agricultural business level. Scope: As with the 2005-06 Agriculture Census, the scope of the 2006-07 Agricultural Survey includes units flagged as having both agricultural activity and an Estimated Value of Agricultural Operations (EVAO) of $5,000 plus or a Standardised BAS Total Sales (SBTS) of $5000 plus. SBTS is an 'EVAO equivalent' and is calculated by applying ANZSIC based standardisation factors to BAS Total sales for ATOMP units. ABNs identified through ABS frame maintenance activities as not operating an agricultural property are excluded from scope. The number identified on the ABR-based frame (190,000) excludes known duplicate/multiple ABNs from related entity units (a related entity group is a group of ABNs which could all report the same activity on the same parcels of land leading to duplication of reporting) and also ABNs identified through ABS frame maintenance activities as not operating an agricultural property. Sample size: The 2006-07 Agriculture Survey is expected to increase to around 35,000 units (a sampling fraction of about 21%). The previous Agriculture Survey (2004-05) included around 31,000 units (a sampling fraction of around 24%). Target RSEs for the survey: RSE constraints on the design variables will be in the order of: 3% for Australian level constraints; 7% for State level constraints; and 15% for Statistical Division and NHT2 constraints. These constraints were set at 2.5%, 6% and 12% respectively for the 2004-05 reference year and earlier survey years. Response rate: The 2006-07 Agricultural Survey budget allocation provides for an overall response rate of 80%, which is equivalent to that achieved in previous surveys.
Estimates will be aggregated into various statistical tables/datasets stored on the ABS Information Warehouse. Datasets will include: Area and production data for all commodities at the national, state and Statistical Division levels; Industries by estimated value of agricultural operation; Industries by area of holding; Industries by Australian Standard Geographical Classification; and Commodities by yields. Publications Principal Agricultural Commodities, Australia, Preliminary (ABS Cat. No. 7111.0). This release contains area and production data, plus comparative data for earlier years, for key commodities at the national and state levels only. Key commodities released in the preliminary estimates include: Principle crops (wheat, barley, grain sorghum and oats) Livestock (Milk cattle, meat cattle, sheep and pigs) Agricultural Commodities, Australia (ABS Cat. No. 7121.0). This release will contain final estimates for area and production of the main commodities collected in the 2006–07 Agricultural Survey. It will contain detailed statistics on broadacre crops, fruit and vegetables as well as the number of livestock and livestock products. Also includes details of industry structure including counts of agricultural businesses by ANZSIC 2006 and size (physical and economic). ABS website releases Preliminary estimates are expected to be released November 2007. This release will feature the preliminary commodity set released at the national and state level. Final estimates at the Australian, state and Statistical Division, are expected to be released on the ABS website in June 2008. This release is expected to contain final estimates for area and production of the main commodities. Customised output In addition to the suite of standard publications customised data output such as cross classified and small area data will be available through the various ABS information consultancies units. Standard data will be made available to information consultancy staff in each state via the datasets contained in the ABS Information Warehouse while specialised, cross classified and other custom generated data will be provided by staff in the Clients Services Section of the Agriculture Business Statistics Centre in Hobart.

What is the expected total number of businesses you will attempt to contact (ie total sample size initially drawn)? How has this been set? (H4)
Within a single cycle, there may be variation between preliminary and final estimates due to biased early response patterns. For example, late responses from large remote locations in Western Australia can affect the early estimates for such items as Area of Holding (which are not normally released as preliminary estimates) and cattle numbers.
The frame is expected to include a large number of out-of-scope units and units that are related to other in-scope units (requiring the identification of duplicates). It is expected that around 15% of the frame will be out-of-scope or a secondary related entity (duplicate) of other in-scope units. The proportion of units expected to be defunct is expected to be very small, but unknown.
The main objectives of the 2006-07 Agricultural Survey testing program was to test new sharefarmer related questions and an expanded suite of water use questions. Testing was conducted in January and February 2007. As the proposed 2006-07 Agricultural Survey form is closely based on the 2005-06 Agricultural Census form, with only a small amount of new content, only limited testing was required. The new sharefarmer questions were proposed for the final live survey form with the aim to reduce respondent burden by better streaming of the effected providers through the survey form. It was hoped that the new questions would also minimise the need for follow-up contact with effected providers. During testing the new sharefarming questions performed less than satisfactorily. As a result it has been decided that these questions will require further testing/refining before being used. The expanded suite of water use questions proposed for the final survey form had been used in previous Agricultural Surveys and also in the 2002-03 Water Survey. These questions had a series of minor amendments made to make them easier to understand/answer and to improve the quality of the data. Testing showed the suite of water use questions to be performing satisfactorily and recommended their inclusion on the 2006-07 Agricultural Survey form.
Annual meetings of users are held in each State. A national User Advisory Group consisting of the major State and national government users and peak industry bodies (e.g. NFF) is convened annually.

The Agricultural Survey is a single stage, stratified random sample. Selections are undertaken by the Agriculture Statistics Centre.
Have extremely large Estimated Value of Agricultural Operations (EVAO) or Area of Holding (AOH); or Are significant contributors to major commodities. The sub-state regional stratification used is based on Statistical Divisions. Australian Capital Territory and Northern Territory are both fully sampled and have no 'sub-territory' stratification. The sample is expected to meet Relative Standard Error (RSE) constraints at National, State and regional levels for Area of Holding and major commodities. The list of major commodities is determined separately for each area of interest (e.g. each State has a different set of major commodities) and includes all commodities which make a significant contribution to the Value of Agricultural Commodities Produced of the area. For area of holding and most major commodities, the RSE constraints are around 3% at national level, 7% at State level and 15% at regional level (SD and NHT2).

Is the survey a new survey or a cycle of an existing repeated survey? (A7)
The current strategy is for a 5 yearly census with sample surveys in intercensal years. The recent cycles have been: 1996-97 census; 1998-99 sample survey; 1999-2000 sample survey; 2000-01 census; 2001-02 to, and including, 2004-05 sample surveys; and 2005-06 census; 2006-07 sample survey.
When the Agricultural Census moved from the ABS maintained frame to the ABR-based frame for the 2005-06 cycle there was a break in series. To alleviate some problems associated with this break bridged estimates were produced in addition to the standard estimates. The 2006-07 Agricultural Survey will carry over the majority of data items used in the 2005-06 Agricultural Census. Whilst there was a break in series for the 2005-06 cycle because of the change in frame, other data definitions were carried across and continue to be used: Estimated value of agricultural operations scope cut off has remained at $5,000 since 1993-94 collection cycle. Most core commodities are carried over from cycle to cycle and also from the intercensal Agricultural Survey. Most commodities will have the same unique Commodity Code Number which allows for comparison over time.
Limitations on the type of respondent (e.g. ABARE collects for data from a limited range of ANZSIC industry groups/classes). The Agricultural Census ABR-based frame includes all respondents engaged in agricultural activity, with an estimated value of agricultural operations of $5,000 or more, regardless of their ANZSIC industry group/class; Limitations on the number of commodities covered, e.g. industry or Government surveys that collect data specific to a particular industry. The Agricultural Census aims for a comprehensive set of statistics about all agricultural activity conducted on the agricultural business (unit) surveyed; The potential for overlap between the Agricultural Census/survey and ABARE has been investigated. The potential savings of approximately 300 respondent hours is minimal (about 1.5 % of total time taken); Reporting bias is a concern when considering any voluntary survey as an alternative source; and Alternative data sources may have too small a sample size to enable the provision of data on a finer geographic resolution other than national/state level.
What consideration has been given to working with other agencies to make their data more suited to your needs? (C3)
Examples of agencies consulted include: SCARM Standing Committee of Agricultural Resource Managers NCASS National Committee on Agricultural Statistics NFF National Farmers Federation DAFF Department of Agriculture, Forestry and Fisheries ABARE Australian Bureau of Agriculture and Resource Economics BRS Bureau of Rural Science There have been ongoing discussions between ABS and ABARE regarding collection rationalisation. The Agriculture Business Statistics Centre recognises the need to minimise overlap between Agricultural Census/Surveys and relevant ABARE surveys. As mentioned in Section C2, the potential for overlap between the Agricultural Census/survey and ABARE has been investigated. Return to Quality Framework |
