SA4 Agriculture Water Use - Businesses Involved 2015-2016

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 2015-16 Agricultural Census. Categories included are statistics on water use, water sources, irrigation expenditure and irrigation methods. Data is aggregated to 2011 ASGS SA4 boundaries.\n\nThe Agricultural Census is conducted once every five years. The scope of the 2015-16 Agricultural Census was all businesses undertaking agricultural activity recorded on the Australian Bureau of Statistics’ Business Register (ABSBR) above a minimum threshold applied to the estimated value of their agricultural operations. The threshold for the 2015-16 Agricultural Census was all agricultural businesses with an Estimated Value of Agricultural Operations (EVAO) of $40,000 or greater. This is a change from previous ABS Rural Environment and Agricultural Collections, where a EVAO threshold of $5,000 or greater was used. As a result of the change in scope, the estimates from the 2015-16 Agricultural Census will not be directly comparable to previously published Agricultural Censuses or annual Rural Environment and Agricultural Commodity Survey outputs. The 2015-16 Census final estimates are based on the achieved target response rate of 85% from an in-scope population of approximately 103,400 agricultural businesses. \n\nThe estimates in this dataset are based on information obtained from agricultural businesses that responded to the 2015-16 Agricultural Census. 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%20Notes12015-16?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2015-16年澳大利亚农业普查（Agricultural Census），按统计区域四级（Statistical Area Level 4, SA4）划分的澳大利亚用水统计纳入企业数量的最终估算值。涵盖的统计类别包括用水量、水源、灌溉支出及灌溉方式相关数据，所有数据均按2011年澳大利亚地理统计标准（Australian Statistical Geography Standard, ASGS）的SA4区域边界进行聚合。

农业普查每五年开展一次。2015-16年农业普查的覆盖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的企业，且其农业经营估算价值达到最低阈值。2015-16年农业普查的阈值为农业经营估算价值（Estimated Value of Agricultural Operations, EVAO）达40000澳元及以上的农业企业。这与澳大利亚统计局此前的乡村环境与农业普查系列（ABS Rural Environment and Agricultural Collections）不同，此前采用的EVAO阈值为5000澳元及以上。由于覆盖范围调整，2015-16年农业普查的估算值无法与此前发布的农业普查或年度乡村环境与农业商品调查（Rural Environment and Agricultural Commodity Survey）结果直接比较。2015-16年普查的最终估算值基于约103400家符合覆盖范围的农业企业所达成的85%目标应答率。

本数据集的估算值基于对2015-16年农业普查作出应答的农业企业提供的信息。但由于并非所有入选企业均提供数据，因此估算值存在抽样变异性，即其可能与从所有企业收集信息后得出的数值存在差异。多数已发布估算值的相对标准误差（Relative Standard Error, RSE）低于10%。对于部分特定商品产量有限的州及领地，其RSE高于10%。RSE高于50%的估算值被认为可靠性不足，不适用于通用场景，因此已从数据集中移除。
