Statistical Area (SA2) Boundary Analysis

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.

Residential SupplyHousing Development & Building Approvals in Plympton

Table Chart PROFILE FAQ

1,113 new dwellings have been approved in Plympton over the past five years, an average of 222 a year. That places the area in the 86th percentile for residential development activity nationally, about 8 approvals per 1,000 residents a year. Of the 223 dwellings approved in the latest reporting year, 39% were detached houses and the rest townhouses or apartments. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Residential building approvals across Plympton have averaged approximately 222 dwellings annually, generating 1,113 homes over the past 5 financial years. With an inflow rate of 1.7 new residents arriving per new home each year across the past 5 financial years (between FY-22 and FY-26), construction aligns closely with demand to maintain balanced local property market conditions, with new dwellings carrying an average expected construction cost of $347,000. Additionally, commercial development approvals reached $116.5 million this financial year, underscoring substantial commercial investment and building activity within the area. Development volume in Plympton outpaces the broader metropolitan area, tracking 23.0% above regional average per person over the 5 year period compared to Greater Adelaide, which provides buyers with varied housing options while underpinning existing real estate values.

Approvals for new residential buildings consist of 39.0% detached dwellings and 61.0% attached dwellings. This emphasis on medium and higher density development provides more attainable price points for first home buyers, downsizers, and property investors. This trend marks a clear departure from the historical urban fabric where houses constitute 58.0% houses, illustrating fewer remaining greenfield sites, evolving lifestyle choices, and a pressing requirement for diversified, budget-conscious housing types. Averaging roughly 126 people per dwelling approval, the locality displays typical growth corridor characteristics. According to the latest quarterly demographic projections from AreaSearch, Plympton is slated to add 6,423 residents through to 2041.

Jobs & IndustryEmployment Trends in Plympton

Table Chart PROFILE FAQ

17,607 residents of Plympton are employed, from a labour force of 17,961. Unemployment sits at 2.0%, with participation at 73.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.9% 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

Plympton is characterised by a qualified local workforce, strong representation across foundational service industries, an exceptionally low unemployment rate of 2.0%, and an annual employment gain of 6.9%. Employed residents totalled 17,607 as of March 2026, while the local jobless rate sat 1.9% below Greater Adelaide's 3.8% benchmark. Labour force participation also tracked considerably higher than typical regional levels at 73.2% compared to Greater Adelaide's 66.4%. At the Census, working from home was reported by 10.6% of residents, though this metric should be viewed in light of prevailing Covid-19 restrictions at the time.

The primary employment fields for local residents comprise health care & social assistance, accommodation & food, and retail trade. Conversely, the manufacturing sector accounts for only 5.2% of the local workforce, trailing Greater Adelaide's 7.0% share. Although jobs exist locally, comparison of Census workplace destinations against resident worker counts suggests that a substantial proportion of the community commutes outside the area for employment. According to an AreaSearch evaluation combining SALM and ABS figures, the region saw a 6.9% rise in employment alongside a 6.0% expansion in the labour force between March 2026 and the preceding twelve months, which led to a 0.8 percentage point decrease in unemployment. This trend differs from the Greater Adelaide area, where employment grew by 4.2%, the labour force grew by 4.0%, and the unemployment rate dropped by 0.2 percentage points. Forecasts from Jobs and Skills Australia for Mar-26 provide additional context regarding anticipated future demand in Plympton. These five- and ten-year projections have been overlaid with local employment data to estimate potential growth trajectories. Although national employment is projected to grow by 6.6% over five years and 13.7% over ten years, expansion varies considerably across different industry sectors. When these sector-specific forecasts are applied to Plympton's current employment structure, the area is expected to see a 6.9% increase in employment over five years and a 14.3% increase over ten years. This calculation uses a straightforward weighting method for demonstration only and does not incorporate local population projections.

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 — 351 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (26,480 at the 2021 Census → 28,715 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 (404031107). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Plympton SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Plympton page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Plympton data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Aug 2026), property sales & rents (Sep 2026), infrastructure projects (Jul 2026) and services & amenities (Sep 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Sep 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
