The PLIDA Board held a meeting on 24 June 2026.
Topics discussed included:
- The PLIDA Board Annual Report 2025-26 was distributed and endorsed by the Board. It gives an introductory and high-level overview on PLIDA and covers a wide range of updates on integrated data at the ABS, key metrics and a historical overview on access to integrated data. Members provided feedback on the document, and the report is now available on the ABS website.
- PLIDA Update:
- With the PLIDA Board membership review in the last meeting, the Terms of Reference annual update was reviewed. The Board agreed that the Annual Report and ToR will be updated to the ABS website simultaneously.
- Spine Enhancements
- The ABS has paused this work program while delivering the next Person Linkage Spine update. However, the ABS have identified several enhancements which will be implemented in the new upcoming Spine build.
- Expansion of historical scope of the Spine datasets to improve historical data in PLIDA and improve the ability to link historical cohorts into the asset.
- Further refinement and identification of the ATO Client Register: Due to low-quality data, some of the register is normally dropped from the Spine. However, due to the use of Splink probabilistic linkage the ABS is able to accept more units from the register.
- Quarterly refreshes of address and demographic information on the spine between annual spine builds.
- Births, Death and Migrants data was investigated to possibly add to the Spine, but more work is needed. This work has also been paused for the upcoming Spine build process but will be resumed later in preparation for a future Spine update process. Generally, the ABS has found that these datasets are not required as spine datasets except where there are temporal or other known gaps in existing spine datasets.
- After the Spine build, there will be further testing and announcement of Births, Deaths and Migration enhancements to continue improving the spine and ensure there are no unforeseen impacts on linkage processes.
- The ABS has paused this work program while delivering the next Person Linkage Spine update. However, the ABS have identified several enhancements which will be implemented in the new upcoming Spine build.
- The Chair asked the Board to think about the future development of PLIDA operating model as well as the PLIDA Strategy for discussion at the October 2026 meeting.
