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
Duffy has an estimated 3,514 residents, up from 3,395 at the 2021 Census — a change of 119 people, or 3.5%. Growth has averaged 1.1% a year over five years. That puts 1,255 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
In the suburb of Duffy, the population is estimated at around 3,514 as of Aug 2026, following AreaSearch analysis of ABS population updates for the wider area alongside 10 validated new addresses added since the Census date. This represents an addition of 119 people (3.5%) relative to the 2021 Census count of 3,395 people, incorporating the ABS June 2025 release of ERP data. This resident count produces a density of 1,255 persons per square kilometer, which exceeds the benchmark among national locations evaluated by AreaSearch. Moreover, Duffy's 3.5% expansion since the 2021 census outperformed the broader SA3 area (1.9%), establishing the locality as a regional growth leader.
This population gain was predominantly fueled by overseas migration, which made up approximately 67.0% of recent population additions. Demographic projections for the suburb of Duffy incorporate ABS/Geoscience Australia SA2 modelling released in 2024 with 2022 as the base year, supplemented by ACT Government SA2 age group growth rates (with 2022 as a base) for non-covered areas and periods post-2032. Long-term outlooks place the suburb in the lower quartile of statistical areas evaluated by AreaSearch, with aggregated SA2-level projections anticipating an increase of 81 persons to 2041, representing cumulative growth of 2.3% over the 16 years.
Frequently Asked Questions - Population
28 new dwellings have been approved in Duffy over the past five years, an average of 5 a year. That is 1.7 approvals per 1,000 residents. Approvals are currently running at an annualised 6, broadly in line with 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
Residential building approvals allocated from ABS statistical area figures indicate that Duffy has averaged around 5 home approvals per year, summing to an estimated 28 homes across the past 5 financial years, with 6 approvals registered in FY-25 to date. Between FY-21 and FY-25, the locality saw an average of 6.7 people arriving annually for every new home constructed, meaning residential demand has outstripped new supply and placed upward pressure on local pricing. The expected construction cost for newly approved dwellings averages $281,000, remaining below regional figures and supporting accessible build costs, while commercial building activity remains subdued with $209,000 in commercial development approvals recorded this financial year.
Residential building volumes in Duffy remain 56.0% below regional average per person compared to Australian Capital Territory, a constrained level of building activity that reinforces demand for the existing dwelling stock and highlights local market maturity alongside possible planning limitations. Medium and high-density housing comprises 60.0% of new building activity while detached houses make up 40.0%, marking a structural transition from the current stock of 88.0% houses to offer more accessible price points for downsizers, first-home buyers, and investors in an established area tracking around 772 people per approval. Urban growth forecasts based on the latest AreaSearch quarterly estimate show Duffy expanding by 81 residents through to 2041. At prevailing construction levels, future residential supply is positioned to satisfy this expected demand comfortably, creating favorable conditions for property purchasers and potentially facilitating growth beyond baseline expectations.

1,798 residents of Duffy are employed, from a labour force of 1,887. Unemployment sits at 4.7%, with participation at 68.0%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,694, 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
Duffy sustains a qualified professional workforce with a strong presence in essential services, recording an unemployment rate of 4.7% based on AreaSearch statistical aggregations. As of March 2026, 1,798 residents are employed, with the local jobless rate standing 0.7% above Australian Capital Territory's 4.1% mark and the labour participation rate tracking at 68.0% against 70.6% across the Australian Capital Territory. Furthermore, Census figures indicate that 14.7% of local workers performed their duties from home, subject to the context of Covid-19 pandemic restrictions. The resident workforce is predominantly engaged across public administration & safety, professional & technical, and health care & social assistance industries.
In contrast, accommodation & food accounts for a smaller employment share at 5.0%, trailing the 6.5% regional benchmark, with Census comparisons between local resident counts and internal working population figures confirming that the suburb functions primarily as a residential district with limited internal commercial job opportunities. Aggregated SALM and ABS metrics show that over the 12-month period, the local labour force expanded by 1.1% while employment fell by 0.6%, leading to a 1.6 percentage points rise in the unemployment rate, whereas Australian Capital Territory recorded a 0.3% rise in employment, a 1.1% workforce increase, and a 0.7 percentage points rise in unemployment. According to Jobs and Skills Australia national forecasts from Mar-26, which project broader employment gains of 6.6% over five years and 13.7% over ten years, local employment weighting suggests Duffy's workforce mix would yield growth of 6.5% over five years and 13.2% over ten years.

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 — 10 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,395 at the 2021 Census → 3,514 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.
