SA4 Farm Management and Demographics - Estimates 2015-2016

This dataset presents the management and demographics of farms in Australia by Statistical Area Level 4 (SA4), from the 2015-2016 Agricultural Census. 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: 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%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2015-2016年澳大利亚农业普查中，按统计区域级别4级（Statistical Area Level 4, SA4）划分的农场经营管理与人口统计特征数据。数据以2011年澳大利亚地理空间统计标准（Australian Statistical Geography Standard, ASGS）划定的SA4区域边界进行聚合统计。 农业普查每五年开展一次。2015-16年度农业普查的覆盖范围为：记录于澳大利亚统计局商业登记册（Australian Bureau of Statistics Business Register, ABSBR）中、开展农业活动且农业经营估计价值达到最低门槛的所有经营主体。2015-16年度农业普查的门槛为：农业经营估计价值（Estimated Value of Agricultural Operations, EVAO）不低于40000澳元的农业经营主体。这与此前澳大利亚统计局农村环境与农业收集项目（ABS Rural Environment and Agricultural Collections）所采用的5000澳元及以上的EVAO门槛有所不同。由于覆盖范围的调整，2015-16年度农业普查的估算结果无法与此前发布的农业普查数据或年度农村环境与农业商品调查（Rural Environment and Agricultural Commodity Survey）产出直接进行对比。2015-16年度普查的最终估算数据基于约103400家符合覆盖范围的农业经营主体中，达成85%的目标应答率所获取的信息。 本数据集的估算数据来源于参与2015-16年度农业普查并作出应答的农业经营主体。但由于并非所有入选的经营主体均提供了数据，因此估算结果存在抽样变异性，即其可能与从所有符合条件的经营主体收集全部信息后得到的统计结果存在差异。绝大多数已发布的估算数据的相对标准误差（Relative Standard Error, RSE）低于10%。对于部分特定商品产量有限的州及领地，其对应估算数据的RSE高于10%。相对标准误差超过50%的估算数据被认为可靠性不足，不适用于通用场景，因此已从数据集中移除。 本数据集为经澳大利亚统计局（Australian Bureau of Statistics）许可使用的ABS数据（目录号：7121.0）。 如需了解该数据集的更多信息，请访问[澳大利亚统计局](http://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/7121.0Explanatory%20Notes12015-16?OpenDocument)。 请注意： * 相对标准误差（Relative Standard Error, RSE）超过50%的估算数据因可靠性不足不适用于通用场景，已从数据集中移除 * 未发布或不适用的数据记录已被设置为空值（null）
