Grange (SA)

An assessment of population growth drivers in Grange reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on ABS population updates and AreaSearch validation, as of November 2025, the Grange (SA) statistical area (Lv2) has an estimated population of around 6,868. This reflects a growth of 725 people since the 2021 Census, which reported a population of 6,143. The change is inferred from AreaSearch's estimate of 6,576 residents following examination of ABS's latest ERP data release in June 2024 and an additional 100 validated new addresses since the Census date. This results in a density ratio of 1,929 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. The Grange (SA) (SA2)'s population growth of 11.8% since the 2021 census exceeded both state (8.7%) and metropolitan area averages, marking it as a growth leader in the region. Overseas migration contributed approximately 95.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering projected demographic shifts, a population increase just below the median is expected for the Grange (SA) (SA2), with an anticipated growth of 712 persons by 2041 based on aggregated SA2-level projections, reflecting an overall increase of approximately 3.5% over the 17-year period.
