Population Density

This resource is a map of coastal population areas for statistical Areas level 2. ABS Population and people themed data items published in 2022 by Statistical Areas Level 2 (SA2), 2021This dataset presents a range of data items sourced from a wide variety of collections, both Australian Bureau of Statistics (ABS) and non-ABS. The data is derived from the 22 November 2023 release of Data by region (DBR) . Individual data items present the latest reference year data available on DBR. This layer presents data by Statistical Areas Level 2 (SA2), 2021.The Population and people theme is based on groupings of data within Data by region (DBR). Concepts, sources and methods for each dataset can be found on the Data by region methodology page.The Population and people theme includes:    Estimated resident population (including age by sex)    Births and deaths    Internal and overseas migration    Census dataWhen analysing these statistics, care needs to be taken as time periods, definitions, methodologies, scope, and coverage can differ across collections. Some data values have been randomly adjusted or suppressed to avoid the release of confidential data. In some cases small cells have been randomly altered to zero. Care should be taken when interpreting cells with small numbers or zeros.

本资源为针对2级统计区域（Statistical Areas Level 2, SA2）的沿海人口区域地图。基于2021年版2级统计区域（SA2）、由澳大利亚统计局（Australian Bureau of Statistics, ABS）于2022年发布的人口与民生主题数据项，本数据集涵盖了来自ABS及非ABS机构多类数据源的多项数据内容。
本数据集的数据源自2023年11月22日发布的《区域数据》（Data by region, DBR），各数据项均采用DBR中可获取的最新参考年份数据。本图层基于2021年版2级统计区域（SA2）呈现相关数据。
人口与民生主题基于《区域数据》（DBR）内的数据分组逻辑构建，各数据集的概念、数据源与方法学说明可查阅《区域数据》方法学页面。
人口与民生主题包含以下内容：
· 估计常住人口（含分年龄、分性别统计数据）
· 出生与死亡人口数据
· 国内及海外移民数据
· 人口普查数据
在分析此类统计数据时需谨慎，因为不同数据源的时间周期、定义、方法学、适用范围及覆盖群体均可能存在差异。部分数据值已进行随机调整或隐藏，以避免泄露涉密信息；部分小型统计单元的数据已被随机置零。解读含少量数值或零值的统计单元时需格外谨慎。
