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 is approximately 2,864 as of February 2026. This represents an increase of 135 people, a 4.9% rise from the 2021 Census figure of 2,729 people. The growth is inferred from ABS data: Clarendon's estimated resident population was 2,859 in June 2024, with five new addresses validated since the Census date. This results in a population density of 23 persons per square kilometer. Clarendon's growth rate is competitive, being within 1.5 percentage points of its SA3 area (6.4%). The primary driver for this growth was interstate migration, contributing approximately 57.5% of overall population gains.

Other factors such as natural growth and overseas migration also played positive roles. 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 or years post-2032, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and released in 2023, with adjustments made using a weighted aggregation method from LGA to SA2 levels. Future population trends indicate an increase just below the median of statistical areas analysed by AreaSearch. By 2041, Clarendon is projected to expand by 381 persons based on the latest annual ERP population numbers, reflecting a total gain of 13.1% 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. In FY-26 so far, there have been three recorded approvals. On average, 1.8 new residents arrive annually for each new home built between FY-21 and FY-25, suggesting a balanced supply and demand creating stable market conditions. However, this has intensified 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 expected cost of $175,000, reflecting more affordable housing options.

This year, $528,000 in commercial development approvals have been recorded, demonstrating Clarendon's residential nature. Compared to Greater Adelaide, Clarendon maintains similar construction rates per person, preserving market equilibrium with surrounding areas. All new constructions since FY-21 have been standalone homes, preserving the area's low density nature and attracting space-seeking buyers.

The estimated population count of 591 people per dwelling approval reflects its quiet development environment. AreaSearch quarterly estimates forecast Clarendon to gain 376 residents by 2041. Existing development levels appear aligned with future requirements, maintaining stable market conditions without significant price pressures.
