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
Klemzig has an estimated 6,653 residents, down from 6,713 at the 2021 Census. That puts 2,651 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 AreaSearch evaluations combining broader ABS demographic updates with 31 validated new addresses confirmed since the Census date, the suburb of Klemzig had an estimated resident count of 6,634 following the ABS ERP release in June 2025, reaching approximately 6,653 as of Aug 2026. This represents a contraction of 60 people (0.9%) compared to the 2021 Census total of 6,713 people. In terms of spatial concentration, the suburb of Klemzig records 2,650 persons per square kilometer, positioning it within the top quartile among locations evaluated across the country. Inward migration from overseas served as the principal demographic driver, accounting for roughly 74.0% of all population expansion in recent times.
Demographic forecasting models incorporate 2024 ABS/Geoscience Australia data anchored to a 2022 baseline for local SA2 zones, complemented by 2023 SA State Government LGA-level projections based on 2021 benchmarks for subsequent horizons past 2032 through weighted aggregation. Across the 16 years leading up to 2041, SA2-level figures anticipate that the suburb of Klemzig will expand by 858 persons, translating to an overall growth rate of 12.6% and placing it above the median pace observed in AreaSearch statistical area tracking.
Frequently Asked Questions - Population
203 new dwellings have been approved in Klemzig over the past five years, an average of 40 a year. That is 5.2 approvals per 1,000 residents. Of the 35 dwellings approved in the latest reporting year, 89% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 7, well below 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 indicates that approximately 40 dwellings receive planning consent each year in Klemzig, encompassing an aggregate of 203 homes across the 5 financial years from FY-21 to FY-25, alongside 7 approvals logged to date in FY-25. While local numbers contracted in recent periods, construction flow has remained broadly balanced, featuring an average residential building cost of $406,000. Furthermore, commercial building approvals have reached $7.3 million during this financial year, underscoring the predominantly residential landscape. Per capita residential consents in Klemzig stand at roughly two-thirds of the Greater Adelaide benchmark, placing the area in the 16th percentile nationwide, which constrains new stock availability and reinforces interest in established residences.
Current construction shows detached houses comprising 89.0% of approvals and attached dwellings making up 11.0%, maintaining a traditional suburban fabric oriented toward family living. This detached share exceeds the 68.0% recorded at Census, highlighting sustained appetite for standalone houses in an established neighbourhood that records roughly 948 people per approval. Based on the most recent quarterly projections from AreaSearch, Klemzig is slated to gain 839 residents by 2041. Given the prevailing trajectory of building activity, future residential additions appear well positioned to satisfy local requirements, ensuring supportive conditions for home seekers and allowing for potential population growth beyond baseline estimates.

3,514 residents of Klemzig are employed, from a labour force of 3,626. Unemployment sits at 3.1%, with participation at 64.8%. 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. The working-day population is estimated at 5,141, about 77% 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
Drawing from aggregated district figures, Klemzig exhibits an unemployment rate of 3.1% alongside a well-credentialed resident labour base concentrated in community and essential services. By March 2026, employed residents numbered 3,514, with the local jobless rate tracking 0.7% under the Greater Adelaide benchmark of 3.8%, while labour force participation closely tracks the metropolitan level of 66.4%. Census figures recorded 10.4% of working residents operating from home, an outcome potentially shaped by pandemic-era movement restrictions. Local workforce participation is primarily oriented around retail trade, education & training, and health care & social assistance.
In contrast, construction constitutes 6.3% of resident employment, trailing the broader 8.7% regional figure. A comparison between Census resident workers and local job counts points to a predominantly suburban residential setting with relatively fewer commercial employment positions located within its borders. Over the year ending March 2026, ABS and SALM monitoring indicates that Klemzig recorded a 0.8% drop in its workforce and a 1.3% dip in employment, pushing the local unemployment rate up by 0.5 percentage points, whereas Greater Adelaide registered an employment expansion of 4.2%, a labour pool increase of 4.0%, and a 0.2 percentage point drop in joblessness. National outlooks published by Jobs and Skills Australia in Mar-26 project nationwide job expansion of 6.6% across five years and 13.7% over ten years. When weighted against Klemzig's specific industry distribution, purely illustrative projections suggest local employment could rise by 6.9% across five years and 14.3% over ten years, independent of local demographic 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 — 31 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (6,713 at the 2021 Census → 6,653 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.
