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 analysis of ABS population updates for the broader area, the estimated population of the suburb of Grange (SA) as of May 2026 is around 6,279. This reflects an increase of 136 people since the 2021 Census, which reported a population of 6,143 people. The change is inferred from the resident population of 6,205 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 101 validated new addresses since the Census date. This level of population equates to a density ratio of 1,763 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration that contributed approximately 95.0% of overall population gains during recent periods.

AreaSearch is adopting 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. Anticipating future population dynamics, a population increase just below the median of national statistical areas is expected for the suburb of Grange (SA), with an expected increase of 656 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 9.3% in total over the 16 years.

AreaSearch assessment of residential approval activity sees Grange among the top 30% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers shows Grange had approximately 70 new homes approved annually. Between FY-21 and FY-25, around 351 homes were approved, with a further 67 approved in FY-26. This results in an average of 1.1 people moving to the area per dwelling built over these five financial years.

The average construction value for new properties is $439,000, indicating a focus on premium segment development. Commercial approvals totalled $17.0 million in FY-26. Compared to Greater Adelaide, Grange exhibited moderately higher building activity, 33.0% above the regional average per person over the five-year period. New building activity comprised 70.0% detached dwellings and 30.0% medium and high-density housing.

With around 106 people per dwelling approval, Grange is characterised as a low density area. Population forecasts suggest Grange will gain 582 residents by 2041. Current construction levels should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

The employment environment in Grange shows above-average strength when compared nationally

Grange has a well-educated workforce with essential services sectors well represented. The unemployment rate was 3.3% as of the past year, with an estimated employment growth of 5.2%. As of December 2025, 3,149 residents were in work while the unemployment rate was 0.5% below Greater Adelaide's rate of 3.8%.

Workforce participation was somewhat below standard at 61.9%, compared to Greater Adelaide's 66.0%. According to Census responses, 14.7% of residents worked from home. Leading employment industries among residents comprised health care & social assistance, education & training, and construction. The area showed strong specialization in education & training with an employment share of 1.2 times the regional level.

Conversely, health care & social assistance had lower representation at 15.3% versus the regional average of 17.7%. Employment opportunities locally appeared limited as indicated by the count of Census working population vs resident population. In the 12-month period ending May-25, employment increased by 5.2% alongside labour force increasing by 4.3%, causing the unemployment rate to fall by 0.9 percentage points. National employment forecasts from Jobs and Skills Australia project a growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Grange's employment mix suggests local employment should increase by 6.6% over five years and 13.7% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections.
