Estimated resident population (ERP) is the official measure of the Australian population.

This dataset presents estimated resident population for 30 June 2001 to 30 June 2023 by Statistical Areas Level 2 (SA2s), 2021. Estimates are final for 2001 to 2021, revised for 2022, and preliminary for 2023.

What is ERP?
ERP links people to a place of usual residence within Australia. Usual residence is the address at which a person considers themselves to currently live. ERP includes all people who usually live in Australia (regardless of nationality, citizenship or legal status), with the exception of foreign diplomatic personnel and their families. It includes usual residents who are overseas for less than 12 months out of a continuous 16-month period. It excludes those who are in Australia for less than 12 months out of a continuous 16-month period. ERP is prepared by adding births, subtracting deaths and adding the net of overseas and internal migration to a base population derived from the latest Census of Population and Housing.

The SA2 estimates in this product are subject to some error. Some caution should be exercised when using the estimates, especially for areas with very small populations. Estimates of under three people should be regarded as synthetic due to confidentiality procedures. For further information about the data see: Regional Population Methodology.

Made possible by the Digital Atlas of Australia
The Digital Atlas of Australia is an Australian Government initiative being led by Geoscience Australia. It will bring together trusted datasets from across government in an interactive, secure, and easy-to-use geospatial platform. The Australian Bureau of Statistics (ABS) is working in partnership with Geoscience Australia to establish a set of web services to make ABS data available in the Digital Atlas.
