ABS - Data by Region - Population & People (SA2) 2011-2019

This dataset presents data on population and people available from the ABS Data by Region statistics. This release of Data by Region presents various data for 2011-2019 and Census of Population and Housing data for 2011 and 2016 and is based on the Statistical Area 2 (SA2) 2016 boundaries. The dataset includes information in the following specified areas of population and people: Estimated Resident Population, Working Age Population, Median Age, Births and Deaths, Population Density, Internal and Overseas Migration, Aboriginal and Torres Strait Islander people, Overseas Born Proportion, Religious Affiliation and Speaks language other than English.\n\nData by Region contains a standard set of data for each region type, depending on the availability of statistics for particular geographies. Data are sourced from a wide variety of collections, both ABS and non-ABS. When analysing these statistics, care needs to be taken as time periods, definitions, methodologies, scope and coverage can differ across collections. Where available, data have been presented as a time series - to enable users to assess changes over time. However, when looked at on a period to period basis, some series may sometimes appear volatile. When analysing the data, users are encouraged to consider the longer term behaviour of the series, where this extra information is available.\n\nFor more information please visit the [Explanatory Notes](https://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/1410.0Explanatory%20Notes12014-19?OpenDocument).\n\n AURIN has made the following changes to the original data:\n\n * Spatially enabled the [original data](https://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/1410.02014-19?OpenDocument) with the [ABS Australian Statistical Geography Standard (ASGS) SA2 2016 dataset](https://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/1270.0.55.001Main+Features10018July%202016?OpenDocument).\n\n * Some data values in Data by Region have been randomly adjusted or suppressed to avoid the release of confidential details.\n\n * Where data was not available, not available for publication, nil or rounded to zero in the original data, it has been set to null.\n\n * Columns and rows that did not contain any values in the original data have been removed.\n

本数据集收录澳大利亚统计局（Australian Bureau of Statistics, ABS）区域统计数据（Data by Region）中的人口与民生相关数据。本次发布的Data by Region涵盖2011-2019年各类统计指标，以及2011年、2016年人口与住房普查数据，统计边界采用2016版统计区域2（Statistical Area 2, SA2）标准。数据集包含以下指定人口与民生领域信息：估计常住人口、劳动年龄人口、年龄中位数、出生与死亡数据、人口密度、国内及海外移民数据、原住民与托雷斯海峡岛民群体、海外出生人口占比、宗教信仰及非英语语言使用情况。

Data by Region包含适用于各区域类型的标准数据集，具体取决于特定地理区域的统计可得性。数据来源涵盖ABS及非ABS的多类统计收集项目。在分析此类统计数据时需格外注意：不同统计项目的时间周期、定义、方法论、统计范围与覆盖情况可能存在差异。若有可用数据，均已整理为时间序列格式，以便使用者评估随时间推移的变化趋势。但部分序列在逐期对比时可能出现波动，因此建议使用者在分析数据时，结合可获取的额外信息，考量序列的长期变化特征。
