ABS - Index of Household Advantage and Disadvantage (IHAD) (SA2) 2016

This dataset presents information from 2016 at the household level; the percentage of households within each Index of Household Advantage and Disadvantage (IHAD) quartile for Statistical Area Level 2 (SA2) 2016 boundaries.\n\nThe IHAD is an experimental analytical index developed by the Australian Bureau of Statistics (ABS) that provides a summary measure of relative socio-economic advantage and disadvantage for households. It utilises information from the 2016 Census of Population and Housing.\n\nIHAD quartiles: All households are ordered from lowest to highest disadvantage, the lowest 25% of households are given a quartile number of 1, the next lowest 25% of households are given a quartile number of 2 and so on, up to the highest 25% of households which are given a quartile number of 4. This means that households are divided up into four groups, depending on their score.\n\nThis data is ABS data (catalogue number: 4198.0) used with permission from the Australian Bureau of Statistics.\n\nFor more information please visit the [Australian Bureau of Statistics](https://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/4198.0Main+Features12016?OpenDocument).\n\nPlease note: \n\n * AURIN has generated this dataset through aggregating the [original SA1 level data](https://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/4198.02016?OpenDocument) (with calculated number of households/quartile) to SA2 level.\n\n * The number of occupied private dwellings, and number of households in each of the IHAD quartiles for each SA2 were calculated by aggregating the values of each of those specified columns from the SA1 dataset. Percentages of households in each of the IHAD quartiles were calculated for each SA2 from these aggregated totals.\n\n * A household is defined as one or more persons, at least one of whom is at least 15 years of age, usually resident in the same private dwelling. All occupants of a dwelling form a household. For Census purposes, the total number of households is equal to the total number of occupied private dwellings (Census of Population and Housing: Census Dictionary, 2016 cat. no. 2901.0).\n\n * IHAD output has been confidentialised to meet ABS requirements. In line with standard ABS procedures to minimise the risk of identifying individuals, a technique has been applied to randomly adjust cell values of the output tables. These adjustments may cause the sum of rows or columns to differ by small amounts from table totals.\n

本数据集涵盖2016年家庭层面的统计信息，具体为基于2016年二级统计区域（Statistical Area Level 2, SA2）边界划分下，各家庭优势与劣势指数（Index of Household Advantage and Disadvantage, IHAD）四分位组内的家庭占比。

家庭优势与劣势指数（IHAD）是澳大利亚统计局（Australian Bureau of Statistics, ABS）开发的实验性分析指数，用于量化家庭相对社会经济优势与劣势水平，数据来源于2016年人口与住房普查。

IHAD四分位分组规则如下：将所有家庭按劣势程度从低到高排序，其中劣势最低的25%家庭被记为四分位组1，次低的25%家庭记为四分位组2，依此类推，直至劣势最高的25%家庭被记为四分位组4。即家庭将根据其指数得分被划分为4个组别。

本数据集使用经澳大利亚统计局授权的官方数据，其目录编号为4198.0。

请注意：

* 本数据集由AURIN通过将[原始一级统计区域（Statistical Area Level 1, SA1）数据](https://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/4198.02016?OpenDocument)（已计算家庭数量/四分位组）聚合至SA2层级生成。

* 各SA2的已入住私人住宅数量，以及各IHAD四分位组内的家庭数量，均通过聚合SA1数据集中对应指定列的数值计算得到；各SA2的IHAD四分位组家庭占比，则基于上述聚合后的总数值进一步计算得出。

* 家庭的定义为：通常居住于同一私人住宅内的一名或多名人员，且其中至少有一名年满15周岁。住宅内的所有居住者共同构成一个家庭。根据普查标准，家庭总数量等于已入住私人住宅的总数量（来源：2016年《人口与住房普查：普查词典》，目录编号2901.0）。

* IHAD输出结果已进行匿名化处理，以符合澳大利亚统计局的相关要求。为遵循澳大利亚统计局的标准流程，降低个体识别风险，已采用随机调整输出表格单元格数值的处理方法，此类调整可能导致表格行/列的求和结果与总表数值存在小幅偏差。
