Projections from ABS and Geoscience Australia, published in 2024 with a 2022 baseline, are utilized by AreaSearch for each SA2 area. In cases where SA2 data is unavailable, and for periods beyond 2032, regional and LGA projections by age bracket published by the SA State Government in 2023 (using 2021 data) are applied, adjusted using a weighted aggregation method of population growth from LGA to SA2 levels. Based on these anticipated demographic trends, the region is projected to experience population growth slightly below the median of regional localities nationwide, with the population set to rise by 1,675 individuals by 2041 compared to the latest annual ERP statistics, representing a total increase of 9.7% over the 16 years.
