This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Detail
In the suburb of Marden, population figures reach approximately 2,802 as of Aug 2026, calculated through AreaSearch's evaluation of regional ABS updates alongside validated post-Census addresses. This represents an addition of 157 people (5.9%) compared to the 2,645 people recorded in the 2021 Census. AreaSearch established this trajectory from an estimated resident population base of 2,787 using the ABS June 2025 ERP release, combined with 21 validated new addresses registered following the Census. The suburb of Marden displays a density ratio of 2,643 persons per square kilometer, placing the community in the upper quartile among locations assessed nationally by AreaSearch.
Over the preceding ten years, the suburb of Marden achieved steady momentum with a 1.6% compound annual growth rate that exceeded the broader SA3 area. The primary catalyst for local demographic expansion was overseas migration, generating roughly 92.0% of total population additions during recent periods. Projections for the suburb of Marden utilise 2024 ABS/Geoscience Australia SA2 modeling with a 2022 baseline, supplemented where necessary and beyond 2032 by the SA State Government's 2023 age-cohort LGA forecasts (derived from 2021 data) weighted and aggregated to the SA2 level. Future projections indicate demographic expansion sitting slightly under the national statistical area median, with the suburb of Marden anticipated to add 266 persons to 2041 under aggregated SA2 projections, representing an overall rise of 9.0% across the 16 years.
Frequently Asked Questions - Population
124 new dwellings have been approved in Marden over the past five years, an average of 24 a year. That is 8.3 approvals per 1,000 residents. Of the 23 dwellings approved in the latest reporting year, 43% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 11, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Dwelling consent figures assessed by AreaSearch from ABS statistical area data show the locality averaging approximately 24 approved residential dwellings annually, culminating in roughly 124 homes across the preceding 5 financial years. Within FY-25 to date, 11 approvals have been documented. With an average of 1.3 new residents per year per dwelling constructed across the last 5 financial years (from FY-21 to FY-25), local housing production aligns closely with demand to preserve market stability, while expected construction costs average $615,000 per dwelling, highlighting developer concentration on upmarket, higher-end properties. Furthermore, commercial approvals totaling $11.3 million have been recorded this financial year, underscoring ongoing non-residential development.
Per capita building approval volumes surpass the wider region, tracking 37.0% above the Greater Adelaide 5 year period benchmark, ensuring ample purchaser choice while sustaining established asset values despite recent moderation in activity. Approvals comprise 43.0% detached houses alongside 57.0% townhouses or apartments, delivering accessible entry points for downsizers, first-home purchasers, and investors seeking higher-density formats. Exhibiting around 291 people per dwelling approval, the locality displays typical low density attributes. Long-term forecasts anticipate an increase of 251 residents through to 2041 relative to the latest AreaSearch quarterly estimate. At prevailing build rates, residential supply appears poised to satisfy incoming demand, supporting favorable market conditions for purchasers and creating capacity for growth to outpace current projections.

1,683 residents of Marden are employed, from a labour force of 1,720. Unemployment sits at 2.2%, with participation at 70.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.0% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
A well-qualified resident workforce characterizes the community, marked by robust essential service employment, an unemployment rate standing at only 2.2%, and 5.1% annual employment expansion according to AreaSearch statistical aggregations. Across the locality as of March 2026, 1,683 residents are employed, the jobless rate sits 1.7% below the Greater Adelaide mark of 3.8%, and labour participation reaches 70.4% versus 66.4% across Greater Adelaide. Remote work uptake was modest at 11.1% in Census returns, though figures may reflect prevailing Covid-19 lockdown conditions. Key employment pillars for residents include health care & social assistance, education & training, alongside professional & technical services.
Professional & technical roles exhibit distinctive local concentration, registering 1.3 times the regional average share. In contrast, construction captures 5.6% of workers, trailing the 8.7% Greater Adelaide standard. A comparison between Census working figures and local resident tallies suggests substantial numbers travel beyond the immediate area for work despite local employment options. Broader SALM and ABS figures aggregated by AreaSearch reveal that during the 12 months to March 2026, local employment expanded by 5.1% alongside a 4.7% rise in the labour pool, reducing local unemployment by 0.3 percentage points (compared to Greater Adelaide's 4.2% employment rise, 4.0% labour force gain, and 0.2 percentage points jobless decline). Future labor requirements can be evaluated against Jobs and Skills Australia's Mar-26 industry projections, which model five-year national expansion of 6.6% and ten-year gains of 13.7%. Applying these sectoral projections against local occupational distributions implies employment growth of 7.0% over five years and 14.4% over ten years (representing a baseline weighting extrapolation that omits localized population forecasts).

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 21 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,645 at the 2021 Census → 2,802 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to Aug 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL40828). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
