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. These state projections lack age category splits, so AreaSearch applies proportional growth weightings from ABS Greater Capital Region projections (released in 2023, based on 2022 data). Nationally, statistical areas are projected to have above median population growth, with Alderley expected to grow by 1,566 persons to 2041, reflecting a total increase of 21.4% over the 17 years.
