This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
An assessment of population growth drivers in Clarendon reveals an overall ranking slightly below national averages considering recent, and medium term trends
Based on AreaSearch's analysis, Clarendon's population was around 2899 as of May 2026. This reflected an increase of 170 people, a growth rate of 6.2%, since the 2021 Census which reported a population of 2729 people. The change was inferred from the estimated resident population of 2899 from the ABS as of June 2025 and an additional five validated new addresses since the Census date. This level of population equated to a density ratio of 23 persons per square kilometer, indicating ample space per person. Clarendon's growth rate since the 2021 census exceeded that of the SA3 area at 5.8%, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 50.5% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.
AreaSearch adopted 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 by age category were adopted, released in 2023 and based on 2021 data, with adjustments made using weighted aggregation methods from LGA to SA2 levels. Examining future trends, a population increase just below the median of statistical areas analysed was expected, with the area projected to expand by 360 persons to reach 3259 by 2041 based on the latest annual ERP population numbers, reflecting an overall gain of 12.4% over the 16-year period.

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 13 dwelling approvals per year over the past five financial years, totalling 67 homes. As of FY26, there have been 7 recorded approvals. On average, 1.8 new residents arrive annually for each new home built between FY21 and FY25, indicating balanced supply and demand. However, this has increased to 7.2 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply. New properties are constructed at an average cost of $175,000, which is below regional norms, offering more affordable housing options.
This year, Clarendon has seen $528,000 in commercial development approvals, reflecting its residential nature. Compared to Greater Adelaide, Clarendon maintains similar construction rates per person, preserving market equilibrium with surrounding areas. All new constructions have been standalone homes, maintaining the area's low density and attracting space-seeking buyers.
As of now, there are an estimated 591 people in the area per dwelling approval. By 2041, Clarendon is forecasted to gain 360 residents according to AreaSearch's latest quarterly estimate. Current development levels appear aligned with future requirements, maintaining stable market conditions without significant price pressures.

Employment
AreaSearch analysis of employment trends sees Clarendon performing better than 90% of local markets assessed across Australia
Clarendon has an educated workforce with significant representation in essential services sectors. Its unemployment rate was 1.5% as of December 2025, lower than Greater Adelaide's 3.8%. Employment grew by 4.5% over the past year.
As of December 2025, 1,775 residents were employed with a workforce participation rate of 72.6%, higher than Greater Adelaide's 66.0%.

However, accommodation & food services are under-represented with only 4.5% of Clarendon's workforce compared to Greater Adelaide's 6.8%. The area may have limited local employment opportunities as suggested by Census data comparing working population to resident population. Between December 2024 and December 2025, employment increased by 4.5%, labour force grew by 4.6%, leading to a slight unemployment rise of 0.1 percentage points. In contrast, Greater Adelaide saw employment grow by 4.2% with a 3.9% labour force expansion and a 0.3 percentage point decrease in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Clarendon's employment mix indicates potential local employment increases of 6.4% over five years and 13.5% over ten years, though these are simple extrapolations for illustrative purposes and do not account for localized population projections.
