AreaSearch utilizes the demographic projections compiled by the ABS and Geoscience Australia released in 2024, using 2022 as their starting point. In instances where specific SA2 regions lack this coverage, and to calculate figures beyond 2032, AreaSearch applies the age-specific growth projections published by the ABS in its 2023 Greater Capital Region release, which relies on 2022 data. Looking at future demographic changes, the region is projected to experience growth slightly below the median national rate, with the population rising by 465 individuals by 2041 according to the most recent annual ERP statistics, representing an overall increase of 6.9% across the 16 years.
