AreaSearch adopts 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, the SA State Government's Regional/LGA projections by age category are used, based on 2021 data and adjusted employing a method of weighted aggregation from LGA to SA2 levels. Future population trends indicate an overall decline in the area's population, with a projected decrease of 93 persons by 2041. However, specific age cohorts are expected to grow, notably the 75 to 84 age group, which is projected to increase by 306 people.
