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.

Sales Detail
North Plympton has an estimated 4,230 residents, up from 3,610 at the 2021 Census — a change of 620 people, or 17.2%. Growth has averaged 3.0% a year over five years, faster than 88% of areas nationally. Overseas migration accounts for 97.0% of that increase. That puts 2,783 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 evaluation of broader ABS population updates alongside new addresses verified by AreaSearch post-Census, the suburb of North Plympton has an estimated resident tally of roughly 4,230 as of Aug 2026. This indicates an expansion of 620 people (17.2%) compared to the 3,610 people recorded in the 2021 Census. Such movement is calculated from an estimated resident population of 4,214 determined by AreaSearch via the recent ABS ERP release (June 2025), coupled with 42 validated new addresses registered following the Census. Consequently, population density stands at 2,782 persons per square kilometer, positioning the suburb in the upper quartile across nationwide regions evaluated by AreaSearch.
Outperforming both the broader SA3 region and the state average of 7.7%, the suburb of North Plympton's 17.2% rate of expansion confirms its status as an area growth leader. This expansion was overwhelmingly powered by overseas arrivals, representing roughly 97.0% of all recent population additions. For each SA2 boundary, AreaSearch incorporates ABS/Geoscience Australia projections published in 2024 utilizing 2022 as a base year. Where SA2 locations lack this coverage, or across periods past 2032, South Australian State Government Regional/LGA age-cohort forecasts issued in 2023 (founded on 2021 numbers) are implemented using weighted aggregation from LGA down to SA2 divisions. In light of these anticipated demographic transitions, the suburb of North Plympton is projected to record substantial growth ranking within the top quartile nationwide, adding 977 persons by 2041 under consolidated SA2 figures, which represents an overall 16-year increase of 22.7%.
Frequently Asked Questions - Population
140 new dwellings have been approved in North Plympton over the past five years, an average of 28 a year. That places the area in the 85th percentile for residential development activity nationally, about 7 approvals per 1,000 residents a year. Of the 33 dwellings approved in the latest reporting year, 39% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 78, 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
Analysis of ABS building approvals by AreaSearch, distributed from statistical boundaries, indicates that North Plympton has averaged roughly 28 residential approvals annually, delivering an estimated 140 homes across the preceding 5 financial years. Within FY-25 to date, 78 approvals have been documented. With approximately 3.6 new residents arriving per year for each home constructed across the past 5 financial years (between FY-21 and FY-25), housing additions are noticeably outpaced by demand, intensifying buyer rivalry and upward price momentum while newly built residences average an expected construction cost of $401,000. Furthermore, $18.9 million in commercial development approvals have been lodged during this financial year, demonstrating steady commercial sector activity.
Relative to Greater Adelaide, building volume in North Plympton is somewhat heightened (running 28.0% above regional average per person over the 5 year period), preserving sound choice for purchasers while underpinning established home values. Medium and higher density dwellings make up 61.0% of new projects (townhouses or apartments), whereas detached houses account for 39.0%. This emphasis on higher-density formats provides more attainable price points that appeal to first-time purchasers, downsizers, and investors. Such a balance diverges noticeably from the current neighborhood fabric (presently 70.0% houses), reflecting tightening land supply alongside shifting buyer lifestyles and affordability requirements. Recording roughly 67 people per dwelling approval, the locality displays typical growth-precinct dynamics. Projections indicate that North Plympton will add 961 residents leading up to 2041 (calculated from the most recent AreaSearch quarterly estimate). While local construction activity is tracking projected population gains at a reasonable pace, buyers could encounter heightened competition as the resident base expands.

2,392 residents of North Plympton are employed, from a labour force of 2,432. Unemployment sits at 1.6%, with participation at 66.5%. 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, so in an area growing as fast as this one it understates the likely rise in local jobs. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
North Plympton possesses a well-educated workforce, with essential services sectors well represented, an unemployment rate of just 1.6%, and 9.1% in estimated employment growth over the past year, based on AreaSearch aggregation of statistical area data. As of March 2026, 2,392 residents are in work while the unemployment rate is 2.2% below Greater Adelaide's rate of 3.8%, and workforce participation is on par with Greater Adelaide's 66.4%. Based on Census responses, a low 10.1% of residents were found to work from home, though Covid-19 lockdown impacts should be considered. Resident employment is primarily anchored by health care & social assistance, retail trade, as well as education & training.
Conversely, manufacturing comprises a smaller share of local workers at 5.5%, falling below the Greater Adelaide level of 7.0%. Although local jobs are present within the neighborhood, comparing the Census working population against resident totals indicates substantial outward commuting. Based on AreaSearch analysis of SALM and ABS data, aggregated from broader statistical areas, over the 12 months to March 2026, employment increased by 9.1% while labour force increased by 8.2%, causing the unemployment rate to fall by 0.8 percentage points. This contrasts with Greater Adelaide, where employment rose by 4.2%, the labour force grew by 4.0%, and unemployment fell 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from Mar-26 can offer further insight into potential future demand within North Plympton. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to North Plympton's employment mix suggests local employment should increase by 6.9% over five years and 14.3% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised 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 — 42 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,610 at the 2021 Census → 4,230 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 (SAL41045). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
