Sales Detail
Holden Hill has an estimated 3,632 residents, down from 3,716 at the 2021 Census — a change of 84 people, or 2.3%. The population has thinned by an average 0.5% a year over five years, slower than 97% of areas nationally. That puts 1,922 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to AreaSearch's review of ABS regional updates alongside 38 validated new addresses recorded since the Census date, the suburb of Holden Hill has an estimated population of approximately 3,632 as of Aug 2026. This indicates a contraction of 84 people (2.3%) compared to the 3,716 people recorded in the 2021 Census, building on an ERP figure of 3,606 derived from ABS data released in June 2025. Across the suburb of Holden Hill, population density reaches 1,921 persons per square kilometer, exceeding the typical benchmark across national locations evaluated by AreaSearch.
Over the preceding ten years, the suburb of Holden Hill recorded steady expansion with a 0.7% compound annual growth rate that surpassed the broader SA3 area, with net population gains underpinned primarily by overseas migration, which accounted for around 91.0% of recent growth. Projections for the suburb of Holden Hill incorporate 2024 ABS/Geoscience Australia SA2 figures pegged to 2022, supplemented where necessary beyond 2032 by the 2023 SA State Government Regional/LGA projections based on 2021 numbers, mapped to SA2 boundaries via weighted population aggregation. Looking forward to 2041, demographic models project an expansion of 255 persons across the suburb of Holden Hill, tracking slightly beneath the national median and representing an overall rise of 6.3% over the 16 years.
Frequently Asked Questions - Population
170 new dwellings have been approved in Holden Hill over the past five years, an average of 34 a year. That is 7.5 approvals per 1,000 residents. Of the 27 dwellings approved in the latest reporting year, 70% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 7, 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
ABS building approvals compiled by AreaSearch show that Holden Hill has maintained a development pace of approximately 34 dwellings approved annually, amounting to roughly 170 homes across the past 5 financial years. During FY-25 to date, 7 approvals have been logged. In the context of recent population contraction, this influx of residential supply helps satisfy local requirements and broadens choices for prospective purchasers, with construction costs averaging $334,000 per dwelling. Furthermore, commercial building approvals have reached $17.1 million during this financial year, demonstrating ongoing capital investment in non-residential assets. Per capita residential construction in Holden Hill tracks 62.0% above the wider Greater Adelaide average, giving buyers plentiful alternatives even as recent activity has eased.
The composition of new residential building remains heavily weighted toward detached houses at 70.0%, while medium and high-density housing makes up 30.0%, sustaining the neighborhood's low-density fabric and appeal to those seeking space. An established residential environment is further evidenced by a ratio of roughly 451 people per dwelling approval. Long-term forecasts indicate that Holden Hill will gain 229 residents by 2041 relative to AreaSearch's latest quarterly baseline. Ongoing construction volumes appear well placed to satisfy incoming housing demand, preserving balanced market conditions for purchasers and potentially facilitating population gains beyond baseline projections.

1,843 residents of Holden Hill are employed, from a labour force of 1,931. Unemployment sits at 4.6%, with participation at 65.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.6% 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
Holden Hill possesses an educated resident workforce with substantial representation in essential industries, maintaining an unemployment rate of 4.6% according to AreaSearch's regional analysis. With 1,843 residents employed as of March 2026, local joblessness sits 0.7% higher than the Greater Adelaide figure of 3.8%, while participation closely tracks the wider metropolitan rate of 66.4%. Data from the Census indicated that only 9.1% of workers performed their duties from home, an outcome influenced by prevailing Covid-19 restrictions at the time. Local workers are largely employed across health care & social assistance, retail trade, and education & training.
The area exhibits a distinct concentration in transport, postal & warehousing, where the workforce proportion is 1.4 times greater than the regional benchmark. Conversely, education & training accounts for only 8.2% of the local workforce, trailing Greater Adelaide's 9.3%. A comparison between Census working figures and the resident population suggests that a substantial proportion of employed residents travel outside the suburb for work. Analysis of ABS and SALM figures indicates that in the year leading to March 2026, the local labour force contracted by 0.8% and employment fell by 1.6%, pushing the unemployment rate up by 0.8 percentage points. In contrast, Greater Adelaide recorded a 4.2% lift in employment, a 4.0% increase in the labour force, and a 0.2 percentage point decline in unemployment. Looking ahead, Jobs and Skills Australia's Mar-26 industry forecasts provide a guide for future labor demand. When applying nationwide projections—which anticipate total growth of 6.6% over five years and 13.7% over ten years—to Holden Hill's industry distribution, local employment is modeled to rise by 6.6% over five years and 13.8% over ten years (calculated as a weighted illustrative extrapolation excluding localized demographic changes).

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 — 38 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,716 at the 2021 Census → 3,632 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.
