2016 SoE Built Environment Population-weighted density change, selected cities, 2011–14

Population density metrics for 2011 Statistical Area Level 2 (SA2) within 2011 Greater Capital City Statistical Areas (GCCSA), including SA2 Population-weighted density (PWD) for 2011 and 2014, PWD change 2011-2014, and ERP population counts by density classes. Selected Density Classes were based on the Australian Population Density Grid published by the ABS, December 2014 (cat. no. 1270.0.55.007). Corresponding population metrics for 2011 GCCSAs. PWD using standardised 1km grid cells provides a more comparable measure of the density in larger regions. It does this by weighting the density using the proportion of population living at that density. In this way the density measure reflects the density at which people actually live. This removes the effect of large unpopulated areas that may be within the regions being compared. In this way comparisons between regions are more valid.\r\n\r\nThe map service can be viewed at http://soe.terria.io/#share=s-AgXEN0N0Q95icRW7M9JIC9IYBdE\r\n\r\nDownloadable spatial data also available below.\r\n\r\nMap prepared by the ABS and presented as Figure BLT3 in Built environment theme of the 2016 State of the Environment Report, available at http://www.soe.environment.gov.au.

本数据集涵盖2011年大首府统计区（Greater Capital City Statistical Areas, GCCSA）范围内的2011年二级统计区域（Statistical Area Level 2, SA2）的人口密度指标，包含2011年与2014年的SA2人口加权密度（Population-weighted density, PWD）、2011至2014年PWD变化量，以及按密度分级统计的估计常住人口（Estimated Resident Population, ERP）计数。所选密度分级依据澳大利亚统计局（Australian Bureau of Statistics, ABS）2014年12月发布的《澳大利亚人口密度网格》（分类编号：1270.0.55.007）制定，同时提供2011年GCCSA对应的人口统计指标。采用标准化1km网格单元计算的PWD，可为更大范围区域的人口密度提供更具可比性的衡量标准：该指标通过以居住于对应密度区间的人口占比作为权重核算密度，使密度测算结果能够反映人口实际居住的密度水平，消除了待比较区域内大片无人居住区域对测算结果的干扰，从而提升区域间密度比较的有效性。
