AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. As we examine future population trends, an above-median population growth of national statistical areas is projected, with the area expected to grow by 4,650 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 13.4% in total over the 17 years.
