Statistics about the population and components of change (births, deaths, migration) for Australia and its states and territories
Detail
Statistics in this release are commonly known as Estimated Resident Population (ERP). 
 
In this issue, the ABS has rebased the population estimates to the 2021 Census of Population. Rebased estimates supersede all estimates from June 2016, for further information see Methodology used in rebased population estimates, June 2021.

Statistics in this release are impacted by the COVID-19 pandemic and the resulting Australian Government closure of the international border from 20 March 2020.
To ensure the ongoing production of fit-for-purpose official population estimates through the COVID-19 pandemic, the ABS has been assessing the likely impact of changed traveller behaviour on preliminary overseas migration estimates, a component of ERP. The ABS has introduced more frequent revisions to overseas migration to ensure the suite of demographic statistics continue to be of high quality and reflect the most timely data available. Preliminary overseas migration estimates will be revised every quarter over four quarters, instead of once after four quarters, until it becomes final. These more frequent revisions will ensure the most timely and accurate data flows through to ERP.
For further information see the Improvements to estimation of net overseas migration.
The ABS is aiming to reduce data which is duplicated elsewhere on the website. The below table will no longer appear in National, state and territory population and can be found in a new annual publication.
