Detail
Drawing on recent ABS population updates along with address validation carried out by AreaSearch since the Census, the suburb of Plympton Park has an estimated population of approximately 4,130 as of Aug 2026. This represents an addition of 249 people (6.4%) compared to the 2021 Census tally of 3,881 people. This estimate stems from an ERP figure of 4,111 determined by AreaSearch following the June 2025 ABS release, together with 22 validated new addresses recorded after the Census date. Population density stands at 3,441 persons per square kilometer, placing the suburb of Plympton Park in the top quartile among nationally evaluated areas.
Furthermore, the 6.4% expansion since the 2021 census outpaced the SA4 region figure of 6.3%, establishing the community as a regional growth outperformer. The primary catalyst for demographic expansion was overseas migration, which accounted for roughly 65.0% of recent population additions. Projections for the area utilize the 2024 ABS/Geoscience Australia dataset based on 2022 benchmarks. Where SA2 coverage is incomplete, and for the timeframe beyond 2032, figures incorporate the 2023 SA State Government Regional/LGA age cohort forecasts (based on 2021 numbers), applying weighted aggregation from LGA to SA2 geographies. Looking forward, the suburb of Plympton Park is projected to achieve higher population growth than the national median, gaining an estimated 591 persons to 2041 under SA2 aggregations, which corresponds to an overall gain of 13.8% across the 16 years.
Frequently Asked Questions - Population
103 new dwellings have been approved in Plympton Park over the past five years, an average of 20 a year. That places the area in the 63rd percentile for residential development activity nationally, about 5 approvals per 1,000 residents a year. Of the 24 dwellings approved in the latest reporting year, 67% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 28, running ahead of 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 residential building approvals compiled by AreaSearch indicate that Plympton Park has recorded roughly 20 dwelling approvals annually, accumulating to around 103 homes over the past 5 financial years. In FY-25 to date, 28 approvals have been logged. The suburb added an average of 2.4 new residents per year for each completed dwelling across the past 5 financial years (between FY-21 and FY-25), demonstrating solid underlying buyer demand. New residences carry an average construction value of $446,000, sitting slightly above regional benchmarks and highlighting a focus on higher-grade builds. In contrast, commercial building approvals for this financial year stand at $1.1 million, reflecting subdued commercial activity.
Per-capita construction volumes in Plympton Park track 17.0% below the Greater Adelaide benchmark, yet the locality sits within the 74th percentile across the country. Recent building activity is divided between 67.0% detached dwellings and 33.0% attached dwellings, offering a wider selection of medium-density formats that span various price points from standalone family properties to compact, accessible dwellings. Recording roughly 149 people per dwelling approval, the locality displays typical growth-market attributes. Long-term forecasts suggest Plympton Park will expand by 572 residents by 2041 relative to the most recent AreaSearch quarterly release. Current construction pipelines appear well balanced against future housing demand, supporting steady property fundamentals without generating notable pricing strains.

2,384 residents of Plympton Park are employed, from a labour force of 2,462. Unemployment sits at 3.2%, with participation at 71.8%. 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. The working-day population is estimated at 3,010, about 73% of the resident population, so more people leave the area for work than travel in. 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 highly qualified labor force characterizes Plympton Park, supported by strong representation across essential services, an unemployment rate sitting at just 3.2%, and annual job growth estimated at 5.3% according to AreaSearch aggregations. By March 2026, employed residents reached 2,384, while the local jobless rate sat 0.7% lower than the 3.8% recorded across Greater Adelaide. Labor force participation is also notably elevated at 71.8%, compared with 66.4% regionally. According to Census findings, 10.1% of workers carried out their duties from home, though this figure was influenced by Covid-19 lockdown restrictions.
The primary areas of employment for residents include health care & social assistance, retail trade, and education & training. Conversely, manufacturing employs a lower share of the local workforce at 5.0%, trailing the 7.0% mark seen throughout Greater Adelaide. Given the difference between Census working population counts and resident numbers, the predominantly residential suburb offers relatively constrained local employment capacity. AreaSearch analysis of ABS and SALM series shows that in the twelve months to March 2026, local employment grew by 5.3% while the workforce expanded by 4.6%, reducing the local unemployment rate by 0.6 percentage points. Over the same timeframe, Greater Adelaide saw employment and labor supply increase by 4.2% and 4.0% respectively, accompanied by a 0.2 percentage point drop in unemployment. National employment projections from Jobs and Skills Australia as of Mar-26 provide additional context on future labor demand. When applying nationwide industry growth forecasts—projected at 6.6% over five years and 13.7% over ten years—to the local industrial composition, employment for Plympton Park residents is estimated to expand by 7.0% over five years and 14.4% over ten years (calculated via simple weighted extrapolation for illustrative purposes without factoring in localized population adjustments).

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 — 22 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,881 at the 2021 Census → 4,130 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.
