SA4 Agricultural Commodities - Estimates 2016-2017

This dataset presents the estimations of agricultural commodity values and yields in Australia by Statistical Area Level 4 (SA4), from the 2016-17 Rural Environment and Agricultural Commodities Survey (REACS). 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: 7121.0) 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/7121.0Explanatory%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

本数据集基于2016-17年度乡村环境与农业商品调查（Rural Environment and Agricultural Commodities Survey, REACS），提供澳大利亚按四级统计区域（Statistical Area Level 4, SA4）划分的农产品产值与产量估算结果，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边界进行聚合。

乡村环境与农业商品调查（REACS）为年度调查，于两次五年一度的农业普查之间开展。2016-17年度REACS的调查范围为：澳大利亚统计局（Australian Bureau of Statistics, ABS）商业登记册（ABS Business Register, ABSBR）中记录的所有开展农业活动，且其农业经营估算值达到最低门槛的经营主体。具体而言，本次调查覆盖农业经营估算产值（Estimated Value of Agricultural Operations, EVAO）不低于40000澳元的所有农业经营主体。这与此前REACS调查的范围存在调整：此前采用的门槛为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年度的多份乡村环境与农业商品调查数据，以EVAO不低于40000澳元为门槛生成了补充估算值。2016-17年度REACS的最终估算结果基于抽选的30466家农业经营主体的调研数据，最终实现了82.4%的目标应答率。

本数据集的估算结果基于参与2016-17年度REACS的农业经营主体提供的有效信息。但由于抽选的经营主体并非全部提供了数据，因此估算结果存在抽样变异性，即其结果可能与对所有抽选经营主体开展全面调查后得到的数值存在差异。绝大多数已发布的估算结果的相对标准误差（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超过10%。而RSE超过50%的估算结果因可靠性不足，不适用于通用场景，已从数据集中移除。
