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

Somerton Park's population, as estimated by AreaSearch based on ABS population updates and new addresses validated since Nov 2025, is around 6,322. This represents an increase of 511 people from the 2021 Census figure of 5,811, marking an 8.8% growth. The estimated resident population of 6,209 in Jun 2024, following examination of ABS's latest ERP data release and validation of four new addresses since the Census date, indicates this increase. This population density translates to approximately 2,822 persons per square kilometer, placing Somerton Park in the upper quartile nationally according to AreaSearch assessments. Somerton Park's growth rate surpassed both its SA4 region (5.4%) and SA3 area, positioning it as a growth leader. Overseas migration was the primary driver of this population growth.

AreaSearch employs ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, for its projections. For areas not covered by this data and years post-2032, it uses the SA State Government's Regional/LGA projections by age category, adjusted using weighted aggregation methods from LGA to SA2 levels. Future population projections indicate an increase just below the median of statistical areas analysed by AreaSearch. By 2041, Somerton Park is expected to expand by 872 persons, reflecting a total gain of approximately 10.0% over the 17-year period.

Residential development activity is slightly higher than average within Somerton Park when compared nationally

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Somerton Park averaged around 33 new dwelling approvals per year. Over the past 5 financial years, between FY-21 and FY-25, an estimated 167 homes were approved, with a further 10 approved so far in FY-26. Each year, on average, 1.3 new residents are associated with each dwelling constructed during these years.

This suggests a balance between supply and demand, maintaining stable market dynamics. The average value of new dwellings developed is $631,000, indicating that developers are targeting the premium market segment with higher-end properties. In FY-26, there have been $1.4 million in commercial approvals, reflecting a predominantly residential focus. Compared to Greater Adelaide, Somerton Park has similar development levels per person, consistent with broader area trends. New development consists of 41.0% detached houses and 59.0% attached dwellings, marking a shift from existing housing patterns which are currently 63.0% houses.

This trend may indicate diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. Somerton Park has approximately 177 people per dwelling approval, suggesting an expanding market. According to the latest AreaSearch quarterly estimate, the location is projected to add 634 residents by 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
