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
Koroit has an estimated 2,288 residents, up from 2,184 at the 2021 Census — a change of 104 people, or 4.8%. Growth has averaged 1.2% a year over five years. Density is about 55 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
Based on evaluation of ABS population adjustments for the surrounding region, combined with new addresses validated by AreaSearch since the Census, Koroit's population is estimated at around 2,288 as of May 2026. This indicates an expansion of 104 people (4.8%) since the 2021 Census, which recorded a population of 2,184 people. The variation is deduced from the resident population of 2,286, calculated by AreaSearch using the latest ERP data release by the ABS (June 2025) and an additional 73 validated new addresses since the Census date. This population level translates to a density ratio of 54 persons per square kilometer, providing ample space per person.
The 4.8% growth in the suburb of Koroit since the 2021 census outperformed the SA4 region (0.4%), as well as the SA3 area, making it a regional growth leader. Population growth in the suburb of Koroit was mostly driven by overseas migration, which made up approximately 48.0% of total population gains during recent times, though all indicators including natural growth and interstate migration were positive. AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, published in 2024 with 2022 as the base year. For SA2 areas without this data, AreaSearch employs the VIC State Government's Regional/LGA projections published in 2023, adjusting them through weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. Future projections suggest a contraction in the overall population, with the suburb of Koroit expected to lose 659 persons by 2041 under this approach. Nevertheless, expansion in certain age brackets is expected, led by the 85 and over age group, which is projected to grow by 8 people.
Frequently Asked Questions - Population
121 new dwellings have been approved in Koroit over the past five years, an average of 24 a year. That places the area in the 54th percentile for residential development activity nationally, about 10 approvals per 1,000 residents a year. Approvals are currently running at an annualised 14, well below 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 analysis of ABS building approvals allocated from statistical areas, Koroit averages about 24 residential approvals annually, amounting to roughly 121 dwellings over the last 5 financial years. For FY-26 so far, 13 approvals have been registered. With an average of 1.1 new residents per year arriving per new home over the past 5 financial years (between FY-21 and FY-25), demand and supply appear to be in equilibrium, support market stability. Meanwhile, new homes are being built at an average value of $614,000, indicating that developers are focusing on the premium segment with high-end projects.
Furthermore, $5.1 million in commercial development approvals have been recorded this financial year, highlighting the area's predominantly residential character. Compared to Rest of Vic., Koroit has 74.0% more development activity per capita. This volume should offer buyers plenty of choices, even though construction activity has slowed down recently. This level is significantly above the national average, showing strong developer trust in the local market. Additionally, new construction has consisted entirely of detached dwellings, preserving the low-density nature of the area with a focus on detached homes to attract buyers seeking space. With roughly 123 people per dwelling approval, Koroit exhibits the features of a low-density area. Given stable or declining population projections, Koroit may experience less housing pressure, creating favourable conditions for buyers.

1,115 residents of Koroit are employed, from a labour force of 1,125. Unemployment sits at 0.9%, with participation at 59.9%. 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 1,793, about 78% 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
Koroit has a skilled labour force, with strong representation in essential service sectors, and an unemployment rate of only 0.9%, based on AreaSearch statistical area aggregations. As of March 2026, 1,115 residents are employed while the unemployment rate is 2.8% lower than the Regional Vic. rate of 3.7%, and workforce participation is close to Regional Vic.'s 61.1%. Census responses indicate that a low 11.1% of residents worked from home, though COVID-19 lockdown impacts should be taken into account. The primary employment sectors for residents are health care & social assistance, retail trade, and construction.
The area shows a particularly high concentration in retail trade, with employment levels at 1.3 times the regional average. Conversely, professional & technical services are underrepresented, accounting for only 2.9% of Koroit's workforce compared to 4.7% in Regional Vic.. The area seems to provide few local job opportunities, as shown by the comparison of the Census working population against the resident population. Based on AreaSearch analysis of SALM and ABS data from broader statistical areas, over the 12 months to March 2026, labour force levels fell by 6.1% and employment declined by 6.1%, while unemployment remained stable. In comparison, Regional Vic. experienced an employment decline of 0.1% and a labour force decline of 0.3%, with a 0.2 percentage point drop. National employment forecasts from Jobs and Skills Australia from May-25 can provide further context on potential future demand in Koroit. These projections, spanning five and ten years, have been mapped against the local employment profile to estimate growth. While national employment is projected to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly by industry. Applying these industry projections to Koroit's employment profile suggests local employment should rise by 6.0% over five years and 12.9% 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 — 73 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (2,184 at the 2021 Census → 2,288 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.
