description: <div align="left"> <p>Statistical Area Level 1 (SA1s) are geographic areas built from whole Mesh Blocks. Most SA1s have a population of between 200 to 800 people. Whole SA1s aggregate to form Statistical Areas Level 2 (SA2s). SA1s are designed to maximise the geographic detail available for Census of Population and Housing data. SA1s are also used as the building blocks for some ASGS geographies, including the Indigenous Structure, Significant Urban Areas, Urban Centres and Localities, Section of State Structure, and the Remoteness Structure.</p> <p>ASGS hierarchical boundaries are consistent within the same release edition only - combine releases with extreme care</p> <p> <b>Data and geography references </b> <ul> <li>Source data publication: <a href="https://www.abs.gov.au/statistics/standards/australian-statistical-geography-standard-asgs/edition-4-july-2026-june-2031" target="_blank"><u>Australian Statistical Geography Standard (ASGS) Edition 4</u></a> </li> <li>Geographic boundary information: <a href="https://www.abs.gov.au/statistics/standards/australian-statistical-geography-standard-asgs/edition-4-july-2026-june-2031/main-structure-and-greater-capital-city-statistical-areas/statistical-area-level-1" target="_blank"><u>Australian Statistical Geography Standard (ASGS) Edition 4 - Statistical Area Level 1</u></a> </li> <li>Further information: <a href="https://www.abs.gov.au/statistics/standards/australian-statistical-geography-standard-asgs/edition-4-july-2026-june-2031/main-structure-and-greater-capital-city-statistical-areas" target="_blank"><u>Australian Statistical Geography Standard (ASGS) Edition 4 - Main Structure and Greater Capital City Statistical Areas</u></a> </li> <li>Source: <a href="https://www.abs.gov.au/" target="_blank"><u>Australian Bureau of Statistics (ABS)</u></a></li> </ul> </p> <p> <b>Contact the Australian Bureau of Statistics</b> <ul> <li>Email <a href="mailto:geography@abs.gov.au"><u>geography@abs.gov.au</u></a> if you have any questions or feedback about this web service. </li> <li><a href="https://www.subscribe.abs.gov.au/geospatialnews" target="_blank"><u>Subscribe</u></a> to get updates on ABS web services and geospatial products. </li> </ul> </p> <p> <b>Privacy at the Australian Bureau of Statistics</b> <br>Read how the ABS manages personal information - <a href="https://www.abs.gov.au/about/legislation-and-policy/privacy/privacy-abs" target="_blank"><u>ABS privacy policy</u></a>. </p> </div>
