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
The suburb of Plympton Park has an estimated population of around 4,129 as of May 2026, according to analysis of ABS population updates and new addresses validated by AreaSearch. This represents an increase of 248 people, which is a rise of 6.4%, compared to the 3,881 people reported in the 2021 Census. The adjustment comes from a resident population of 4,110, as estimated by AreaSearch after reviewing the latest ERP data release by the ABS in June 2025, plus another 22 newly validated addresses since the Census date. With a density ratio of 3,440 persons per square kilometer, the suburb ranks in the upper quartile among national locations evaluated by AreaSearch.
The 6.4% growth observed since the 2021 census outperformed the SA4 region's growth rate of 6.2%, making the suburb a leading area for population increase in that region. Recent population gains were mainly fueled by overseas migration, which accounted for approximately 65.0% of the total rise during the latest periods. Demographic projections utilize ABS and Geoscience Australia geographic models published in 2024 using 2022 baseline records. For areas without direct coverage, or for periods extending past 2032, state planning forecasts from 2023 utilizing 2021 baselines are integrated using weighted calculations that scale municipal trends down to local sectors. Anticipated growth trends indicate that the locality will expand at a pace exceeding the national median, with the total residency projected to rise by 626 individuals by 2041, representing a total expansion of 14.7% over the course of 16 years.

2,410 residents of Plympton Park are employed, from a labour force of 2,488. Unemployment sits at 3.1%, with participation at 72.8%. 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 2,996, 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
Plympton Park boasts a highly skilled labor pool where essential service industries hold strong representation, alongside a mere 3.1% unemployment rate and an estimated 5.5% employment increase over the previous year according to AreaSearch aggregated statistical area information. By March 2026, there were 2,410 employed residents, with the local joblessness figure sitting 0.7% lower than Greater Adelaide's 3.8% rate, and workforce participation exceeding the typical level at 72.8% versus Greater Adelaide's 66.6%. Census survey results indicate that only 10.1% of inhabitants worked remotely, although the lingering effects of Covid-19 lockdowns must be taken into account when interpreting these figures.
The primary sectors employing local residents are healthcare & social assistance, retail, and education & training. In contrast, manufacturing represents a small portion of the workforce at 5.0% compared to 7.0% across the wider metropolitan area. Given the gap between the count of local workers and resident jobholders, the suburb itself offers relatively few local employment positions. Based on local workforce registries from the year ending March 2026, the number of employed residents grew by 5.5% while the overall labor force expanded by 4.8%, driving a 0.7 percentage point reduction in the unemployment rate. Over the identical timeframe, Greater Adelaide saw employment rise by 4.2% and the labor force grow by 4.0%, yielding a 0.2 percentage point drop in joblessness. Five-year and ten-year federal labor forecasts published in May-25 offer additional context on future demand patterns. Projecting these national industry trends onto the local workforce structure indicates that employment within the suburb of Plympton Park should grow by 7.0% over five years and 14.4% over ten years, assuming local distributions align with national sectoral shifts.

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 May 2026, not a 2021 count (3,881 at the 2021 Census → 4,129 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 May 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.
