For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Considering the projected demographic shifts, an above-median population growth of statistical areas across the nation is projected, with the area expected to grow by 2,126 persons to 2041 based on the latest annual ERP population numbers, reflecting a gain of 13.4% in total over the 17 years.
