Sales Detail
Mannum has an estimated 3,139 residents, up from 2,919 at the 2021 Census — a change of 220 people, or 7.5%. Growth has averaged 1.3% a year over five years. Interstate and internal migration accounts for 82.0% of that increase. Density is about 12 people per 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 demographic updates and newly validated address details compiled by AreaSearch since the Census points to an estimated headcount of approximately 3,139 for the suburb of Mannum as of May 2026. This marks an expansion of 220 residents, or 7.5%, from the 2,919 individuals recorded in the 2021 Census. AreaSearch calculated this shift by starting with a resident population of 3,131 derived from the June 2025 ABS ERP figures, then factoring in 49 new addresses validated since the Census. With this total, the suburb of Mannum registers a density of 12.2 persons per square kilometer, indicating a spacious residential environment.
The 7.5% growth rate observed since the 2021 census outpaces both the wider SA3 territory's 5.9% expansion and the Rest of SA region, positioning the locality as a leading growth hub. The majority of these population increases, accounting for roughly 82.0% of recent growth, were fueled by interstate moves. To project local demographics, AreaSearch uses ABS and Geoscience Australia forecasts issued in 2024, taking 2022 as the baseline. For regions lacking coverage or projections past 2032, regional and municipal projections by age bracket from the SA State Government, published in 2023 using 2021 inputs, are utilized through a custom process of merging growth estimates from municipal to local levels. According to these combined projections, the suburb of Mannum is anticipated to see growth slightly under the median for regional Australian territories, with an expected gain of 151 residents by 2041, translating to a total growth of 4.6% across the 16 years.
Frequently Asked Questions - Population
178 new dwellings have been approved in Mannum over the past five years, an average of 35 a year. That places the area in the 65th percentile for residential development activity nationally, about 11 approvals per 1,000 residents a year. Of the 39 dwellings approved in the latest reporting year, 97% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 50, 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
According to AreaSearch's evaluation of ABS building approval records, Mannum registers roughly 35 new residential building approvals annually. Over the last 5 financial years from FY-21 to FY-25, approximately 178 homes were approved, supplemented by 46 approvals during the current FY-26 period. Local demand matches supply closely, with an average of 1.1 new residents arriving per approved dwelling annually over the 5 financial years spanning FY-21 to FY-25. The typical expected construction cost for these new builds is $415,000, illustrating that builders are targeting high-end housing designs. Meanwhile, business construction remains low, with only $292,000 in commercial approvals logged so far this financial year.
When adjusted per capita, construction activity in Mannum is 102.0% higher than in the Rest of SA, offering a broader range of options for purchasers. This level of building is significantly elevated on a national scale, showing high builder optimism for the local market. The mix of new construction is heavily weighted toward separate houses at 97.0%, with multi-unit projects representing just 3.0% of approvals, which preserves the suburban feel and space suitable for families. With 56 residents for every new permit, the community demonstrates typical growth characteristics. Projections show the resident population expanding by 143 people by 2041. Judging by recent building trends, the delivery of new houses is set to comfortably accommodate this influx, maintaining favorable purchasing conditions and potentially opening the door to even faster growth than currently anticipated.

1,173 residents of Mannum are employed, from a labour force of 1,243. Unemployment sits at 5.6%, with participation at 45.5%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.0% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,612, about 83% 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
Mannum features a mix of white and blue collar jobs, with essential services playing a strong role, an unemployment rate of 5.6%, and an estimated employment growth of 3.3% over the past year, according to AreaSearch aggregation of statistical area data. As of March 2026, 1,173 residents are employed, while the unemployment rate sits 0.2% higher than the Regional SA rate of 5.5%. Workforce participation is notably lower at 45.5% compared to the Regional SA figure of 58.4%. Census data indicates that only 7.4% of residents worked from home, though the effects of Covid-19 lockdowns should be taken into account.
Most working residents are engaged in health care and social assistance, retail, and building services. Health care and social assistance represents a key specialty, employing 1.3 times the proportion seen across the wider region. Conversely, primary industries like farming, logging, and fishing employ only 8.0% of the workforce, which is lower than the 14.5% average for Regional SA. Comparing the local working cohort to the total number of residents suggests that local job vacancies are relatively scarce. Looking at SALM and ABS figures over the year ending March 2026, total employment expanded by 3.3% while the active labor pool grew by 4.4%, leading to a 1.0 percentage point increase in joblessness. By comparison, Regional SA experienced a 1.2% rise in employment, a 2.6% increase in the labor supply, and a 1.4 percentage point rise in unemployment. Long-term occupational forecasts issued by Jobs and Skills Australia in May-25 suggest future workforce requirements. Nationally, job growth is projected at 6.6% over five years and 13.7% over ten years, though individual sectors will perform differently. Applying these industry projections to the local work profile suggests employment in the area could rise by 6.0% over five years and 12.8% 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 — 49 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (2,919 at the 2021 Census → 3,139 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.
