Statistical Area (SA2) Boundary Analysis

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 Seaford stands at approximately 18,369 as of May 2026. This represents a rise of 1,154 people (6.7%) from the 2021 Census, which recorded 17,215 people. This shift is calculated using the ABS estimated resident population of 18,305 from June 2025 and 308 validated new addresses registered since the Census. Such a population size results in a density of 1,477 persons per square kilometer, a figure that is higher than the typical average across locations evaluated nationally by AreaSearch. Seaford's growth of 6.7% since the 2021 census was greater than that of the SA4 region (3.2%) and the SA3 area, establishing it as a regional growth leader.

This population expansion was mostly driven by overseas migration, which made up roughly 54.7% of the total population gains in recent times. AreaSearch implements projections from the ABS and Geoscience Australia for individual SA2 areas, published in 2024 with 2022 as the starting year. For SA2 areas where this data is unavailable, AreaSearch uses the 2023 Regional/LGA projections from the VIC State Government, adjusting them via a weighted aggregation of population growth from the LGA level to the SA2 level. The age group growth rates derived from these aggregations are also applied to all areas for the period from 2032 to 2041. Looking at future demographic developments, the area is projected to experience population growth slightly below the national median, increasing by 1,778 persons by 2041 based on the most recent annual ERP data, which indicates a total growth of 9.3% over the 16 years.

Approvals are currently running at an annualised 76, broadly in line with that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

Seaford averages approximately 84 residential building approvals annually, with 420 homes approved during the last 5 financial years (between FY-21 and FY-25) and 70 recorded so far in FY-26. An average of 2 new residents per year was added for each constructed dwelling over the last 5 financial years (between FY-21 and FY-25), indicating steady demand that helps maintain property values, with new dwellings being constructed at a mean value of $365,000.

Compared on a per capita basis to Greater Melbourne, Seaford has 53.0% more development activity, presenting a wider range of options for purchasers.

Recent building activity consists of 39.0% detached houses and 61.0% townhouses or apartments. This emphasis on medium and high-density housing options offers lower entry prices and is suitable for downsizers, investors, and first-home buyers. This is a clear shift from the current housing stock (which is 74.0% houses), indicating a decline in available land for development, shifting lifestyle preferences, and a demand for more varied, economical housing choices. The region has roughly 246 people per dwelling approval, showing capacity for further expansion.

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 — 308 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (17,215 at the 2021 Census → 18,369 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 (214011375). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Seaford (Vic.) SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Seaford (Vic.) page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Seaford (Vic.) data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Aug 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
