Clapham

Clapham is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of May 2026, the estimated population of the suburb of Clapham is around 1,684 people, reflecting a decrease of 1 person since the 2021 Census. This decrease represents a change of 0.1%. The latest resident population estimate by AreaSearch, based on the ERP data release by the ABS in June 2025 and validated new addresses, is used for this calculation. This results in a population density ratio of 2,187 persons per square kilometer, which is higher than the average seen across national locations assessed by AreaSearch. Overseas migration was the primary driver of population growth in the suburb during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, State Government's Regional/LGA projections by age category are used, adjusted employing a method of weighted aggregation from LGA to SA2 levels. By 2041, the suburb is projected to expand by 17 persons based on aggregated SA2-level projections, reflecting a gain of 1.0% over the 16 years.

The level of residential development activity in Clapham is very low in comparison to the average area assessed nationally by AreaSearch

Clapham has received approximately one dwelling approval annually over the past five financial years, totalling about five homes. As of FY-26, two approvals have been recorded. The population decline during this period suggests that new supply has likely kept pace with demand, providing good options for buyers.

The average construction cost value of new homes is $736,000, indicating a focus on the premium market segment. Compared to Greater Adelaide, Clapham shows significantly reduced construction activity, with 83.0% fewer approvals per person. This scarcity typically boosts demand and prices for existing properties, although building activity has increased in recent years. However, this activity remains lower than national averages, potentially due to market maturity or development constraints. Recent building activity consists solely of detached dwellings, maintaining the area's suburban identity with a concentration of family homes.

With approximately 1121 people per dwelling approval, Clapham exhibits an established market. According to AreaSearch's latest quarterly estimate, the location is projected to add 17 residents by 2041. Given current development patterns, new housing supply should meet demand, offering favourable conditions for buyers and potentially facilitating population growth beyond projections.

Greater Adelaide recorded employment growth of 4.2%, labour force growth of 3.9%, with unemployment falling 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project national employment expansion at 6.6% over five years and 13.7% over ten years, but growth rates differ significantly between industry sectors.
