Somerville

An assessment of population growth drivers in Somerville reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Feb 2026, Somerville's population is around 19,814. This shows an increase of 1,292 people since the 2021 Census, which reported a population of 18,522. The change is inferred from the estimated resident population of 18,972 in June 2024 and an additional 147 validated new addresses since the Census date. This results in a population density ratio of 168 persons per square kilometer. Somerville's growth rate of 7.0% since the 2021 census exceeds that of its SA3 area (3.7%) and SA4 region, indicating it as a growth leader. Natural growth contributed approximately 52.1% to overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises VIC State Government's Regional/LGA projections from 2023, adjusted using weighted aggregation methods to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Based on these projections, Somerville is expected to grow by 2,242 persons to 2041, reflecting a total increase of 7.1% over the 17-year period.

Residential development activity is lower than average in Somerville according to AreaSearch's national comparison of local real estate markets

Somerville has seen approximately 68 new homes approved each year over the past five financial years, totalling 342 homes. As of FY-26, 14 approvals have been recorded. On average, 0.4 new residents per year arrive for every new home built between FY-21 and FY-25, indicating that new supply is keeping pace with or exceeding demand. The average construction value of these properties is $300,000, consistent with regional patterns.

This financial year has seen $17.9 million in commercial approvals, reflecting steady investment activity. Compared to Greater Melbourne, Somerville has about three-quarters the rate of new dwelling approvals per person and ranks among the 36th percentile nationally, suggesting relatively constrained buyer choice and supporting interest in existing homes. New development consists of 71.0% detached dwellings and 29.0% attached dwellings, maintaining the area's traditional low density character focused on family homes. The estimated population per dwelling approval is 567 people, reflecting its quiet development environment.

By 2041, Somerville is projected to grow by 1,400 residents. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current projections.
