Marden

Population growth drivers in Marden are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Marden's population is estimated at around 2,901 as of February 2026. This reflects an increase of 256 people (9.7%) since the 2021 Census, which reported a population of 2,645 people. The change is inferred from the resident population of 2,806 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 18 validated new addresses since the Census date. This level of population equates to a density ratio of 2,736 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Marden's 9.7% growth since the 2021 census exceeded the state (9.0%), along with the Greater Adelaide, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 92.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Anticipating future population dynamics, a population increase just below the median of statistical areas analysed by AreaSearch is expected, with the suburb expected to increase by 308 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 6.8% in total over the 17 years.

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

Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Marden has recorded approximately 15 residential properties granted approval per year over the past five financial years, totalling an estimated 78 homes. In the current financial year FY-26, 11 approvals have been recorded to date. On average, 1.4 new residents have been associated with each dwelling constructed annually between FY-21 and FY-25, indicating a balanced supply and demand dynamic. However, this has intensified to an average of 5 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply. New properties are constructed at an average expected cost value of $836,000, reflecting a developer focus on the premium segment with upmarket properties.

In FY-26, $11.3 million in commercial approvals have been registered, indicating balanced commercial development activity compared to Greater Adelaide. Recent construction comprises 60% detached dwellings and 40% medium and high-density housing, offering choices across price ranges from spacious family homes to more compact options. This favours detached housing more than current patterns suggest (44% at Census), demonstrating ongoing robust demand for family homes despite increasing density pressures.

The location has approximately 252 people per dwelling approval, indicating room for growth. Looking ahead, Marden is expected to grow by 197 residents through to 2041 according to the latest AreaSearch quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Applying these projections to Marden's employment mix suggests local employment should increase by 7.0% over five years and 14.4% over ten years, though these are simple extrapolations for illustrative purposes and do not account for localized population projections.
