Clarendon

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

Clarendon's population, as of November 2025, is approximately 2,854. This figure represents an increase of 125 people since the 2021 Census, which recorded a population of 2,729. The growth is inferred from the estimated resident population of 2,859 in June 2024 and three additional validated addresses since the Census date. This results in a population density of 23 persons per square kilometer. Clarendon's 4.6% growth since the census is comparable to its SA3 area's growth rate of 4.9%. The primary driver of this growth was interstate migration, contributing about 57.5% of overall population gains.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and adjusted using weighted aggregation methods. Future population trends suggest an increase just below the median for statistical areas analysed by AreaSearch, with Clarendon expected to expand by 381 persons to reach a total of approximately 3,235 by 2041, reflecting a gain of about 13.5% over the 17-year period.

Residential development activity is lower than average in Clarendon according to AreaSearch's national comparison of local real estate markets

Clarendon has received approximately 13 dwelling approvals per year over the past five financial years, totalling 67 homes. As of FY26, three approvals have been recorded. On average, 1.8 new residents arrived annually for each new home between FY21 and FY25, suggesting balanced supply and demand. However, this rate has increased to 7.2 people per dwelling over the past two financial years, indicating growing popularity and potential undersupply. New properties are constructed at an average cost of $175,000, below regional norms, offering more affordable housing options.

In FY26, $528,000 in commercial development approvals have been recorded, reflecting the area's residential nature. Clarendon maintains similar construction rates per person compared to Greater Adelaide, preserving market equilibrium with surrounding areas. All new constructions since FY21 have been standalone homes, maintaining low density and attracting space-seeking buyers.

The estimated population per dwelling approval is 591 people, indicating a quiet development environment. According to AreaSearch's latest quarterly estimate, Clarendon is forecasted to gain 386 residents by 2041. Current development levels appear aligned with future requirements, maintaining stable market conditions without significant price pressures.
