AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections are adopted, released in 2023 based on 2021 data. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings aligned with ABS Greater Capital Region projections for each age cohort. Examining future population trends, projections indicate a decline of 100 persons by 2041 according to this methodology. However, specific age cohorts are expected to grow, notably the 85 and over age group, projected to increase by 525 people.

This shift reflects reduced availability of development sites and addresses shifting lifestyle demands and affordability requirements.
