SA4 Agriculture Water Use - Businesses Involved 2016-2017

This dataset presents final estimates of the number of businesses included in the water usage statistics in Australia by Statistical Area Level 4 (SA4) from the 2016-17 Rural Environment and Agricultural Commodities Survey (REACS). Categories included are statistics on water use, water sources, irrigation expenditure and irrigation methods. Data is aggregated to 2016 ASGS SA4 boundaries.\n\nThe REACS is conducted annually in the years between the five-yearly Agricultural Census. The scope of the 2016-17 REACS was all businesses undertaking agricultural activity recorded on the The Australian Bureau of Statistics' Business Register (ABSBR) above a minimum threshold applied to the estimated value of their agricultural operations. The scope for the 2016-17 REACS was all agricultural businesses with an Estimated Value of Agricultural Operations (EVAO) of $40,000 or greater. This is a change from previous REACS collections, where a scope of EVAO of $5,000 or greater was used, and is a continuation of the scope used in the 2015-16 Agricultural Census. As a result of the change in scope, the estimates from the 2016-17 REACS will not be directly comparable to previous published REACS outputs. To address this, additional estimates have been produced from a number of rural environment and agricultural commodity collections from 2010-11 to 2014-15 using an EVAO of $40,000 or greater. The 2016-17 REACS final estimates are based on the achieved target response rate of 82.4% from a sample of 30,466 agricultural businesses selected. \n\nThe estimates in this dataset are based on information obtained from agricultural businesses that responded to the 2016-17 REACS. However, since not all of the businesses that were selected provided data, the estimates are subject to sampling variability; that is, they may differ from the figures that would have been produced if information had been collected from all businesses. Most published estimates have relative standard errors (RSEs) less than 10%. For some states and territories with limited production of certain commodities, RSEs are greater than 10%. Estimates with an RSE greater than 50% are considered too unreliable for general use and hence have been removed from the data.\n\nThis data is ABS data (catalogue number: 4618.0) used with permission from the Australian Bureau of Statistics.\n\nFor more information on the dataset please visit the [Australian Bureau of Statistics](http://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/4618.0Explanatory%20Notes12016-17?OpenDocument).\n\nPlease note: \n\n * Estimates with an RSE value greater than 50% and are considered too unreliable for general use and have been removed from the data\n\n * Where data was not published or not applicable the records have been set to null\n

本数据集呈现了基于2016-17年度《农村环境与农业商品调查（Rural Environment and Agricultural Commodities Survey，REACS）》、按澳大利亚统计区域四级（Statistical Area Level 4，SA4）划分的澳大利亚用水统计中纳入的企业数量最终估算值。统计类别涵盖用水量、水源、灌溉支出及灌溉方式相关数据。所有数据均按2016年澳大利亚统计地理标准（Australian Statistical Geography Standard，ASGS）的SA4区域边界进行聚合。

《农村环境与农业商品调查（REACS）》在每五年一次的农业普查的间隔年度开展。2016-17年度REACS的调查范围为：澳大利亚统计局企业登记册（Australian Bureau of Statistics' Business Register，ABSBR）中记录的所有开展农业活动、且满足农业运营最低门槛要求的企业，具体门槛为农业运营估算价值（Estimated Value of Agricultural Operations，EVAO）不低于40000澳元。本次调查范围相较于此前的REACS调查有所调整——此前的调查门槛为EVAO不低于5000澳元，而本次范围延续了2015-16年度农业普查的门槛标准。由于调查范围的调整，2016-17年度REACS的估算结果无法与此前发布的REACS成果直接对比。为解决这一问题，研究团队基于2010-11至2014-15年度的多份农村环境与农业商品调查数据，采用EVAO不低于40000澳元的标准重新生成了补充估算值。2016-17年度REACS的最终估算值基于抽取的30466家农业经营主体样本，实际完成目标应答率为82.4%。

本数据集的估算值基于2016-17年度REACS的应答农业经营主体提供的信息。但由于并非所有抽中企业均提供了数据，估算结果存在抽样变异性，即其与对所有抽中企业开展调查后得到的结果可能存在差异。多数已发布的估算值的相对标准误差（relative standard errors，RSEs）低于10%；对于部分特定商品产量有限的州和领地，其估算值的RSE高于10%。RSE超过50%的估算值被认为可靠性过低，不适用于通用场景，因此已从数据集中移除。
