AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, they adopt SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, adjusted using weighted aggregation methods. Future population trends suggest an increase just below the median of national areas, with Ridgehaven expected to expand by 482 persons to reach 2041, reflecting a total increase of 10.8% over the 16-year period.
