This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Detail
According to investigations by AreaSearch, the population of Hackham - Onkaparinga Hills is estimated at 7,386 in May 2026. This represents a growth of 511 individuals (7.4%) relative to the 2021 Census, which counted 6,875 residents. This demographic shift is calculated using the June 2025 ABS estimated resident population of 7,376 alongside 244 validated new addresses recorded since the Census. Based on these numbers, the population density stands at 312 persons per square kilometer, indicating low-density living conditions and scope for future expansion. The local growth rate of 7.4% since the 2021 census outpaced the broader SA3 area (5.8%) and the SA4 region, positioning it as a leading growth zone.
A major driver of this growth was interstate migration, which accounted for roughly 58.5% of the total population increases in recent times. Projections from the ABS and Geoscience Australia released in 2024, using 2022 as a baseline, are utilized for each SA2 region. For locations lacking this data or for projections past 2032, population models by age bracket released in 2023 by the SA State Government (relying on 2021 data) are applied via a weighted aggregation process translating LGA growth to the SA2 level. Future trends point to population expansion exceeding the median for national statistical areas, with the locality projected to gain 1,398 residents by 2041 relative to the latest annual ERP statistics, representing an overall increase of 18.8% over the 16 years.

In contrast, professional & technical services are underrepresented, accounting for 4.2% of the workforce compared to a regional average of 7.3%.

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 — 244 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (6,875 at the 2021 Census → 7,386 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.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (403041078). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
