Population
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 around 2,854 as of Aug 2025. This reflects an increase of 125 people since the 2021 Census, which reported a population of 2,729 people. The change is inferred from the estimated resident population of 2,859 in June 2024 and three additional validated new addresses since the Census date. This level of population equates to a density ratio of 23 persons per square kilometer. Clarendon's growth of 4.6% since census positions it close to the SA3 area's growth of 4.8%. Population growth was primarily driven by interstate migration, contributing approximately 57.5% of overall gains.

Development
Residential development activity is lower than average in Clarendon according to AreaSearch's national comparison of local real estate markets
Clarendon has received approximately 12 dwelling approvals per year. The Australian Bureau of Statistics produces development approval data on a financial year basis. Between FY-20 and FY-25, there were 62 approvals in total, with none recorded so far in FY-26. Over the past five financial years, an average of 1.8 people moved to the area for each dwelling built. However, this figure has increased to 7.2 people per dwelling over the past two financial years, indicating growing demand and tightening supply.
The average construction value of development projects is $632,000, suggesting a focus on premium market developments. This year, there have been $528,000 in commercial approvals, predominantly residential. Compared to Greater Adelaide, Clarendon maintains similar construction rates per person, preserving market equilibrium with surrounding areas.
Recent building activity consists solely of standalone homes, maintaining the area's low-density nature and attracting space-seeking buyers. The estimated population count is 591 people per dwelling approval, reflecting its quiet development environment. By 2041, Clarendon is projected to add 386 residents. Construction pace is reasonable with projected growth, but increasing competition among buyers can be expected as the population rises.
