The ABS has revised the original Labour Force series from October 2021 to reflect the latest available preliminary and final estimates of the Estimated Resident Population. This quarterly process ensures that the Labour Force series promptly reflect any change in population trends and minimises the size of revisions that can occur when the series are rebenchmarked following each Census of Population and Housing.
In response to COVID-19 related changes in travel, the ABS has been revising preliminary Net Overseas Migration estimates more frequently. Net Overseas Migration estimates are a component of population estimates, from which Labour Force benchmarks are produced. These revisions have been incorporated into the quarterly rebenchmarking revisions. For more information, please refer to 'Net Overseas Migration revisions in Labour Force benchmarks during COVID-19'.
The usual resident civilian population in March 2023 was revised up by around 0.3% (around 64,000 people).
Revisions to original series also result in revisions to seasonally adjusted series.
The current Labour Force population benchmarks are derived from estimated resident population (ERP) based on the 2021 Census (preliminary rebased ERP).
In the November 2023 publication, to be released on 14 December 2023, the Labour Force population benchmarks will be updated to reflect the latest estimated resident population (ERP) based on the 2021 Census (final rebased ERP). This is a regular 5-yearly rebasing process which follows each Census, and ensures the Labour Force estimates are benchmarked to the most recent population information. This process will result in revisions to Labour Force estimates going back to 2016. This follows a similar process to that undertaken in 2018.
