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
Millicent has an estimated 5,268 residents, up from 5,110 at the 2021 Census — a change of 158 people, or 3.1%. Density is about 34 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
Estimates from AreaSearch indicate that the suburb of Millicent has a population of approximately 5,268 as of May 2026, which is based on an evaluation of ABS population adjustments for the surrounding region and 59 validated new addresses recorded since the Census. This represents a growth of 158 residents (3.1%) relative to the 2021 Census, which documented 5,110 residents. The current figure is calculated from the resident population of 5,268, which was determined by AreaSearch through analyzing the June 2025 ABS ERP statistics combined with subsequent address updates. The resulting population density stands at 33 persons per square kilometer, indicating a spacious residential environment.
This post-census growth rate of 3.1% trail the SA3 region's expansion of 4.9% by 1.8 percentage points, showing solid local growth dynamics. This growth was primarily fueled by interstate migration, which accounted for roughly 73.0% of the total population increase in recent times. Projections for each SA2 region published in 2024, using 2022 as a starting point, are sourced from ABS and Geoscience Australia. Where these forecasts are unavailable, or for periods extending past 2032, figures are derived from the 2023 SA State Government age-cohort projections (based on 2021 data) using a weighted aggregation method from LGA to SA2 boundaries. Future demographic outlooks point to expansion in line with the bottom quartile of national non-metropolitan zones, with aggregate SA2 models predicting the suburb of Millicent will add 154 residents by 2041, representing a total increase of 2.9% across the 16 years.
Frequently Asked Questions - Population
61 new dwellings have been approved in Millicent over the past five years, an average of 12 a year. That is 2.3 approvals per 1,000 residents. Approvals are currently running at an annualised 10, broadly in line with 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
Analysis of ABS building approvals allocated by AreaSearch indicates that the suburb of Millicent averages approximately 12 residential approvals each year, with a total of 61 dwellings authorized over the last 5 financial years. Thus far during FY-26, there have been 10 approvals registered. Because the area averaged only 0.6 new residents per constructed dwelling over the 5 financial years from FY-21 to FY-25, the supply of housing is keeping pace with or exceeding local demand, which offers buyers more options and supports the capacity for growth beyond projected levels.
The average value of these newly approved homes is $369,000, pointing to developer interest in higher-end, premium properties. Furthermore, commercial approvals totaling $4.0 million have been logged in the current financial year, which highlights the predominantly residential makeup of the area. The volume of building approvals in the suburb of Millicent is significantly constrained compared to regional benchmarks, running 53.0% below the average per capita for the Rest of SA. This limited supply of new construction typically helps maintain demand and property values for the existing housing stock. This rate of development also lags behind the national average, pointing to a mature market and possible local planning limitations. The approved residential construction has consisted entirely of detached houses, maintaining the low-density profile of the community and appealing to buyers seeking standalone properties. The ratio of 620 people for every single dwelling approved highlights the quiet and low-turnover nature of the local building market. Looking forward, the population of the suburb of Millicent is projected to expand by 154 residents by 2041, taking the most recent quarterly estimate from AreaSearch as the base. Under ongoing construction rates, the supply of new housing is anticipated to comfortably satisfy demand, maintaining favorable purchasing conditions and potentially enabling growth to outpace current demographic forecasts.

2,309 residents of Millicent are employed, from a labour force of 2,423. Unemployment sits at 4.7%, with participation at 53.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.4% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. 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 displays a mix of white-collar and industrial occupations, with a notable presence of manufacturing jobs, an unemployment rate of 4.7%, and a 3.1% expansion in employment over the preceding year, as compiled by AreaSearch from statistical data. As of March 2026, there are 2,309 working residents. The local unemployment rate is 0.7 percentage points below the 5.5% recorded across Regional SA, while the participation rate is somewhat lower than the regional average, standing at 53.4% compared to 58.4%. Census records show that a minor portion of the workforce, 6.3%, operated from home, although these figures were likely influenced by pandemic-related lockdown measures.
The primary sectors employing local residents are health care & social assistance, manufacturing, and retail trade. The local economy is highly concentrated in manufacturing, with an employment share that is 1.6 times that of the broader region. Conversely, the agricultural, forestry, and fishing sector is underrepresented, employing only 8.6% of the workforce compared to 14.5% across Regional SA. Comparing the count of local workers to resident employees suggests that local employment opportunities within the immediate area are relatively limited. Based on SALM and ABS figures aggregated by AreaSearch for the 12 months leading up to March 2026, local employment grew by 3.1% while the overall labor force expanded by 4.1%, resulting in a rise in the unemployment rate of 0.9 percentage points. Over the same timeframe, Regional SA saw employment rise by 1.2% and the labor force grow by 2.6%, leading to a 1.4 percentage point increase in unemployment. National employment forecasts published by Jobs and Skills Australia in May-25 provide context for future labor demand. These five and ten-year projections have been applied to the local industry distribution to estimate future employment trajectories. Nationally, employment is projected to grow by 6.6% over five years and 13.7% over ten years, though rates vary widely by industry. Applying these trends to the local industry mix suggests that employment for the suburb of Millicent would rise by 5.4% over five years and 12.2% over ten years, representing a basic weighted extrapolation that does not account for local population changes.

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 — 59 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (5,110 at the 2021 Census → 5,268 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.
