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 4,248 residents, up from 3,610 at the 2021 Census — a change of 638 people, or 17.7%. Growth has averaged 3.1% a year over five years, faster than 89% of areas nationally. Overseas migration accounts for 97.0% of that increase. That puts 2,795 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
Analysis of ABS population figures for the surrounding region, combined with post-Census address validation by AreaSearch, indicates the population of the suburb of North Plympton has reached approximately 4,248 as of May 2026. This represents a gain of 638 people (17.7%) compared to the 2021 Census, which recorded 3,610 residents. The updated total is based on a resident population estimate of 4,240 calculated by AreaSearch using the June 2025 ABS ERP release, supplemented by 40 validated new addresses added after the Census. This population level corresponds to a density of 2,794 persons per square kilometer, placing the suburb of North Plympton in the highest quarter of all Australian locations analyzed.
The 17.7% rate of expansion since the 2021 census outpaced both the statewide growth of 7.5% and the local SA3 area, establishing the suburb of North Plympton as a leader in regional growth. The expansion was chiefly driven by overseas arrivals, who accounted for roughly 97.0% of the net population increase over recent times. Projections developed by the ABS and Geoscience Australia for individual SA2 regions, published in 2024 using 2022 as a baseline, are utilized. For any SA2 regions lacking this coverage, or for periods extending past 2032, regional and LGA projections by age group from the SA State Government (released in 2023 using 2021 baseline data) are integrated using a weighted aggregation technique from the LGA to the SA2 level. Based on these anticipated demographic transitions, the suburb of North Plympton is set to experience population growth that exceeds the median of areas assessed by AreaSearch. Specifically, aggregated SA2 projections indicate an expansion of 987 persons by 2041, representing a cumulative increase of 23.1% over the 16 years.
Frequently Asked Questions - Population
165 new dwellings have been approved in North Plympton over the past five years, an average of 33 a year. That places the area in the 76th percentile for residential development activity nationally, about 8 approvals per 1,000 residents a year. Of the 28 dwellings approved in the latest reporting year, 43% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 73, 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
Building approvals data from the ABS, mapped to the local area, indicates that the suburb of North Plympton has averaged approximately 33 new residential approvals annually, translating to roughly 165 new dwellings over the last 5 financial years. Thus far in FY-26, 67 approvals have been logged. With an average of 3.7 additional residents migrating to the area for every completed home between FY-21 and FY-25, demand is running well ahead of supply. This mismatch typically intensifies buyer competition and exerts upward pressure on local pricing. The new residential stock carries an average building value of $379,000, indicating that developers are focusing on the higher-end, premium market.
Furthermore, commercial building approvals have reached $18.9 million during the current financial year, representing a moderate volume of non-residential building activity. Compared to the broader Greater Adelaide region, residential construction activity in the suburb of North Plympton is slightly elevated, running 34.0% above the regional per capita average over the 5 year period. This volume helps sustain local property values while offering options for buyers, even though the pace of development has slowed down recently. Recent building data indicates that detached houses account for 43.0% of new projects, while townhouses and apartments make up 57.0%. This pivot toward higher-density housing provides entry-level pathways and suits downsizers, investors, and first-time buyers. This represents a clear shift from the historical housing stock, which consists of 70.0% houses, reflecting a scarcity of vacant land and aligning with changing lifestyle choices and affordability needs. The suburb of North Plympton averages about 182 people per residential approval, indicating a growing area. Based on the latest quarterly calculations from AreaSearch, the suburb of North Plympton is projected to add 979 residents by 2041. Although residential construction is keeping pace with these demographic forecasts, incoming buyers may face tighter competition as the population continues to expand.

2,422 residents of North Plympton are employed, from a labour force of 2,462. Unemployment sits at 1.6%, with participation at 67.0%. 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
Data compiled by AreaSearch for the suburb of North Plympton reveals a highly educated workforce with strong representation in key service sectors, an unemployment rate of only 1.6%, and an estimated 9.2% growth in employment over the preceding year. As of March 2026, there are 2,422 employed residents. The local unemployment rate sits 2.2% below the Greater Adelaide average of 3.8%, while the labor force participation rate is identical to the regional benchmark of 66.6%. According to Census data, a relatively low share of workers, 10.1%, operated from home, though this figure may be influenced by pandemic-era restriction policies.
The primary employment sectors for residents are health care & social assistance, retail trade, and education & training. By comparison, manufacturing accounts for only 5.5% of local employment, which is lower than the Greater Adelaide figure of 7.0%. Although the suburb of North Plympton provides local jobs, the ratio of the working population to local employment opportunities suggests a significant proportion of residents travel outside the area for their jobs. Analysis of SALM and ABS statistics for the broader area shows that during the 12 months ending March 2026, total employment in the suburb of North Plympton grew by 9.2% and the labor force grew by 8.4%, leading to a decrease in the unemployment rate of 0.8 percentage points. In comparison, Greater Adelaide recorded employment growth of 4.2%, labor force growth of 4.0%, and a decline in unemployment of 0.2 percentage points. National employment projections from May-25 by Jobs and Skills Australia provide further context regarding future trends. These projections, spanning five and ten-year horizons, have been aligned with the local industry profile to estimate future changes. Locally, adjusting for these industry-specific national forecasts suggests employment could grow by 6.9% over five years and 14.3% over ten years, representing a simple weighted extrapolation for demonstration purposes that does not incorporate local population forecasts.

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 — 40 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (3,610 at the 2021 Census → 4,248 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.
