Description: <DIV STYLE="text-align:Left;">The Australian Population grid 2024 was created using 2024 Estimated Residential Population (ERP) by Statistical Area Level 1 2021 (SA1) data. This data was modelled to 1 kilometre square grid cells to represent the population density of Australia (people per square kilometre). This is modelled data and should be used and interpreted with caution.SA1s are defined by the Australian Statistical Geography Standard (ASGS) Edition 3 2021. The grid was constructed using the National Nested Grid Standard.Processing steps:<UL><LI>A subset of the <A href="https://www.abs.gov.au/statistics/research/abs-address-register-users-guide" STYLE="text-decoration:underline;">ABS Address Register</A> was created to represent residential addresses as closely as possible. Indigenous Community Points were included where no AR point existed. SA1 centroid points were included where no AR or ICP point existed within an SA1. All these layers were combined into a single point layer (Allpoints).</LI><LI>The Allpoints layer was overlaid with the SA1 boundaries to give every point an SA1 code. Points without an SA1 code (outside all SA1 regions) were dropped.</LI><LI>ERP by SA1 was averaged across all points within each SA1.Points were converted to raster using the <A href="https://www.anzlic.gov.au/resources/national-nested-grid" STYLE="text-decoration:underline;">National Nested Grid</A> as template. Point population values which fell within each raster cell were summed.</LI></UL> Data and geography references <UL><LI> Main source data publication: <A href="https://www.abs.gov.au/statistics/people/population/regional-population/2023-24" STYLE="text-decoration:underline;">Regional population, 2023–24 financial year</A></LI><LI> Geographic boundary information: <A href="https://www.abs.gov.au/statistics/standards/australian-statistical-geography-standard-asgs-edition-3/jul2021-jun2026" STYLE="text-decoration:underline;">Australian Statistical Geography Standard (ASGS) Edition 3</A></LI><LI> Further information: <A href="https://www.abs.gov.au/methodologies/regional-population-methodology/2023-24" STYLE="text-decoration:underline;">Regional population 2023–24 Methodology</A></LI><LI> Source: <A href="https://www.abs.gov.au/" STYLE="text-decoration:underline;">Australian Bureau of Statistics (ABS)</A></LI></UL>Contact the Australian Bureau of Statistics <UL><LI> Email <A href="mailto:geography@abs.gov.au" STYLE="text-decoration:underline;">geography@abs.gov.au</A> if you have any questions or feedback about this web service. </LI><LI> <A href="https://www.subscribe.abs.gov.au/geospatialnews" STYLE="text-decoration:underline;">Subscribe</A> to get updates on ABS web services and geospatial products. </LI></UL>Privacy at the Australian Bureau of Statistics Read how the ABS manages personal information - <A href="https://www.abs.gov.au/about/legislation-and-policy/privacy/privacy-abs" STYLE="text-decoration:underline;">ABS privacy policy.</A></DIV>
