Collaboration and harmonisation of population projections

4 December 2020

In early 2020, the Council of Australian Governments agreed the National Population and Planning Framework. The Framework was established to promote greater integration between governments in managing and planning for population change. The Centre for Population is working with jurisdictions to implement the Framework.

One of the main goals of the Framework is more consistent and comparable population projections across the Federation. Significant progress in aligning population projections across all states and territories was also announced today, with a national agreement achieved on five core principles:

  • Relevance;
  • Timeliness;
  • Accuracy;
  • Interpretability; and
  • Accessibility.

Officials from states, territories and the Australian Local Government Association (ALGA) agreed to the first stage of harmonisation of population projections to implement these principles. This means greater consistency and greater ease in using and comparing population projections across states and territories, in particular:

  • a common frequency of publication, as opposed to a situation where population projections are released with different frequency across jurisdictions;
  • a common basis for projections to move away from projections based on inconsistent regions or to varying time horizons; and
  • inclusion of notes to explain the projections and provide additional analysis such as scenarios using different assumptions.
