AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and used SA State Government's Regional/LGA projections by age category released in 2023 based on 2021 data for areas not covered by this data and years post-2032. Considering projected demographic shifts, a significant population increase was forecasted with the area expected to expand by 8,452 persons to 2041, reflecting an increase of 24.3% in total over the 16 years.
