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
Aldgate has an estimated 3,596 residents, up from 3,471 at the 2021 Census — a change of 125 people, or 3.6%. Growth has averaged 0.6% a year over five years. That puts 428 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
As of Aug 2026, the suburb of Aldgate has an estimated population of approximately 3,596, according to AreaSearch analysis of broader ABS population updates and new addresses validated since the Census. Compared to the 3,471 people recorded at the 2021 Census, this represents an addition of 125 people (3.6%). This demographic shift is derived from the resident population count of 3,596, determined by AreaSearch after assessing the latest ERP figures released by the ABS in June 2025 along with 4 validated new addresses added since the Census date. With a density of 427 persons per square kilometer, the suburb of Aldgate offers substantial personal space alongside capacity for future growth.
International migration served as the main catalyst for local expansion, generating roughly 71.0% of total population increases over recent periods. Projections published by ABS/Geoscience Australia in 2024, utilising 2022 as the base year, are utilised by AreaSearch across SA2 locations. In instances where SA2 areas lack coverage or for periods post-2032, figures from the SA State Government's Regional/LGA age category projections (issued in 2023 from 2021 data) are incorporated using weighted population growth aggregation transitioning from LGA to SA2 tiers. Demographically, the suburb of Aldgate is projected to record growth tracking slightly beneath the national median for statistical regions. Aggregated SA2-level projections anticipate that the suburb of Aldgate will expand by 258 persons to 2041, representing a cumulative rise of 7.2% across the 16 years.
Frequently Asked Questions - Population
Detail
According to AreaSearch examination of ABS building approval statistics mapped from statistical areas, Aldgate has registered an annual average of approximately 3 new dwelling approvals, accumulating an estimated 18 homes across the past 5 financial years. Within FY-25 to date, 7 approvals have been logged. With an average of 3.2 new residents per year entering for every residence built over the past 5 financial years (between FY-21 and FY-25), residential construction falls considerably short of demand, typically intensifying competition among purchasers and applying upward pressure on prices. Meanwhile, anticipated construction costs for new dwellings average $811,000, indicating that building activity centers on high-end, premium housing.
Furthermore, commercial approvals recorded this financial year total $5.2 million, highlighting the predominantly residential character of the locality. Residential building activity in Aldgate is markedly subdued relative to Greater Adelaide, sitting 85.0% below the regional per-capita rate. Although local building pace has picked up in recent years, the limited volume of new housing generally bolsters demand and values across established stock. Construction levels also track below nationwide benchmarks, indicating development limitations and a mature market. In addition, all recent residential building has consisted entirely of standalone homes, upholding low-density planning and appealing to buyers seeking detached space. Demonstrating this low-intensity development climate, the area records an estimated ratio of 476 people per dwelling approval. Demographic projections show that Aldgate is set to add 258 residents through to 2041 relative to the latest AreaSearch quarterly estimate. If existing construction rates continue, new residential supply may fail to keep pace with population expansion, which would likely heighten competition among buyers and support future price appreciation.

Frequently Asked Questions - Infrastructure
Adelaide's Inner And Outer Ring Route Capacity Improvements
Enhancement of Adelaide's Inner and Outer Ring Routes to alleviate congestion, aiming for integrated urban mobility and addressing impacts from population growth, economic activity, and travel demand.
Adelaide Public Transport Capacity and Access
A multi-year state-led initiative to expand the capacity and reach of Adelaide's public transport network. Key focus areas include the electrification of the Outer Harbor and Belair rail lines, upgrades to the Adelaide Railway Station hub to resolve capacity bottlenecks, and the implementation of the City of Adelaide Integrated Transport Strategy (ITS) endorsed in July 2025. The program aims to support projected growth of 670,000 residents by 2051 through enhanced service frequencies, digital signaling (ETCS), and improved first/last mile access within the CBD.
1,966 residents of Aldgate are employed, from a labour force of 2,012. Unemployment sits at 2.3%, with participation at 67.9%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.2% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,696, about 75% 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
Statistical area data compiled by AreaSearch indicates that Aldgate possesses a well-educated labour force with prominent professional services representation, an unemployment rate standing at only 2.3%, and estimated annual employment growth of 4.6% over the past year. By March 2026, employed residents numbered 1,966, alongside an unemployment rate that sits 1.5% beneath the 3.8% recorded across Greater Adelaide, while labour force participation closely mirrors Greater Adelaide's 66.4%. Census figures revealed that 21.2% of working locals operated from home, though this should be viewed in the context of Covid-19 lockdown conditions.
Local workforce participation is heavily clustered within health care & social assistance, professional & technical, and education & training sectors. Specialisation is exceptionally pronounced in professional & technical services, where the local employment proportion reaches 1.8 times the regional baseline. Conversely, manufacturing accounts for only 3.7% of resident employment, falling short of Greater Adelaide's 7.0%. Comparing Census working population against resident population metrics suggests that this largely residential enclave provides relatively few jobs internally. Over the 12-month period, AreaSearch evaluation of aggregated ABS and SALM data reveals that local employment grew by 4.6% while the labour force expanded by 4.7%, resulting in a 0.1 percentage points uptick in the unemployment rate. Across Greater Adelaide, employment increased by 4.2%, the labour force rose by 4.0%, and unemployment contracted by 0.2 percentage points. Future workforce demand in Aldgate can be evaluated using national projections from Jobs and Skills Australia as of Mar-26 across five and ten-year timeframes applied to the local industry mix. Nationally, job numbers are projected to grow by 6.6% over five years and 13.7% over ten years, with substantial variation across industries. When modelled against Aldgate's specific sector distribution, local employment is projected to expand by 7.2% over five years and 14.6% over ten years (noting this represents an illustrative weighted extrapolation that excludes 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 — 4 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,471 at the 2021 Census → 3,596 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.
