Chart Color Schemes
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
Demographic assessments by AreaSearch indicate that the population of Bacchus Marsh Surrounds stands at approximately 6,812 as of Aug 2026. This represents a gain of 253 people (3.9%) compared to the 2021 Census tally of 6,559 people. This figure is derived from an ABS estimated resident population figure of 6,770 recorded as of June 2025 alongside 186 validated new addresses documented since the Census date. With a density of 6.6 persons per square kilometer, residents enjoy substantial physical space. Outperforming the wider SA3 area (2.8%), Bacchus Marsh Surrounds's 3.9% expansion since the 2021 census establishes it among the regional leaders for population gains.
Inbound interstate migration served as the primary catalyst, generating roughly 50.4% of total population additions over recent timeframes, supplemented by positive inflows from natural growth and overseas migration. Population projections for individual SA2 locations rely on ABS/Geoscience Australia models published in 2024 using 2022 as the base year. Where SA2 coverage is absent, AreaSearch adopts the 2023 VIC State Government Regional/LGA projections, applying a weighted aggregation methodology to translate LGA trends down to SA2 zones. Projected growth patterns by age cohort derived from these aggregations are similarly utilized for the years 2032 to 2041 across every region. Looking ahead over this timeframe, the model projects a net demographic contraction of 491 persons across the locality by 2041. In contrast to this overall decline, select demographic segments are set to expand, particularly the 25 to 34 age bracket, which is slated to add 115 people. Details regarding age breakdowns are provided in the relevant section.

3,685 residents of Bacchus Marsh Surrounds are employed, from a labour force of 3,768. Unemployment sits at 2.2%, with participation at 67.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.1% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 5,905, about 87% 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
The local workforce in Bacchus Marsh Surrounds is characterized by strong skill levels, extensive participation across essential industries, a low jobless rate of 2.2%, and consistent employment metrics over the preceding twelve months. As of March 2026, employed residents total 3,685, while unemployment sits 1.5% beneath the Regional Vic. benchmark of 3.7%, supported by an elevated labor force participation rate of 67.4% against 61.1% across Regional Vic.. Census returns revealed that 23.0% of local workers operated from home, a metric that may reflect temporary COVID-19 restriction measures. The primary sectors supporting local workers are construction, health care & social assistance, as well as public administration & safety.
The construction trade displays exceptional local density, engaging workers at 1.5 times the wider regional proportion. Conversely, health care & social assistance accounts for a smaller share locally at 11.9% relative to 16.8% across the broader region. Discrepancies between local working populations and resident worker counts in the Census indicate that local job generation remains modest. An examination of ABS and SALM figures by AreaSearch reveals that over the 12-month period, the local labor pool expanded by 0.4% while total employed persons dipped by 0.1%, leading to an increase in the unemployment rate of 0.5 percentage points. Across Regional Vic., total employment fell by 0.1% alongside a 0.3% decrease in the overall labor force, resulting in a 0.2 percentage point drop. National employment projections released by Jobs and Skills Australia in Mar-26 provide a framework for evaluating future employment trends in Bacchus Marsh Surrounds. These five- and ten-year national estimates have been applied to the local workforce structure to model future outcomes. While nationwide jobs are projected to rise by 6.6% over five years and 13.7% over ten years, industry expansion rates fluctuate considerably. Applying this sector weighting to the local employment distribution suggests job opportunities could expand by 6.1% over five years and 12.7% over ten years (calculated as an illustrative weighting exercise without incorporating local demographic forecasts).

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 — 186 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (6,559 at the 2021 Census → 6,812 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.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (201021009). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
