Update of employer characteristics
The source of employer characteristics - industry, employment size and sector - has been updated in this release from the week ending 30 December 2023 resulting in revisions to all industry, employment size and sector indexes from this point forward.
This third periodic update has refreshed employer characteristics as well as reduced the number of payroll jobs with 'unknown' employment characteristics improving the quality of impacted indexes. The magnitude of revisions in this update is larger than the last update due to a longer time period between updates and component indexes are impacted differently. For more information, see the Update of employer characteristics section of the Methodology.
The date at which employer characteristics are updated, called 'transition points', can be visible in the levels of some indexes. Users should always exercise caution when comparing week-on-week changes and index levels across transitions points - the latest being the week ending 30 December 2023.
The ABS recommends that analyses of previously published estimates be refreshed with the data from this release.
Seasonality and reporting variability
The movements in payroll jobs estimates at the end and start of the calendar year include large seasonal changes in the labour market - further described in a historical seasonality spotlight article.
Some businesses have reduced activity in late December and early January which may lead to a higher degree of reporting variability over this period. This can result in higher than usual levels of revision for payroll jobs for this period when more normal reporting resumes. Further information is available in the Data variability and revisions section of the Methodology.
