Seven Hills (NSW)

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

Based on ABS population updates and AreaSearch validations, the estimated population of Seven Hills (NSW) as of May 2026 is around 20,980. This reflects an increase of 885 people since the 2021 Census, which reported a population of 20,095. The change was inferred from AreaSearch's estimated resident population of 20,909 in June 2025 and 213 validated new addresses since the Census date. This results in a density ratio of 2,174 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Seven Hills' growth rate of 4.4% since the 2021 census exceeded the SA3 area's growth rate of 4.3%. Overseas migration contributed approximately 67.0% of overall population gains during recent periods.

For projections, AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections are used, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking ahead, the suburb is expected to increase its population by around 1,858 persons to 2041 based on aggregated SA2-level projections, reflecting an overall gain of approximately 8.5% over the 16-year period.

AreaSearch analysis of residential development drivers sees Seven Hills recording a relatively average level of approval activity when compared to local markets analysed countrywide

AreaSearch analysis of ABS building approval numbers in Seven Hills shows around 110 residential properties granted approval each year over the past five financial years ending FY26. This totals an estimated 554 homes. By FY26, 69 approvals have been recorded. Despite population decline, housing supply has remained adequate relative to demand, indicating a balanced market with good buyer choice.

The average value of new homes being built is $401,000. In commercial development, $14.4 million in approvals have been recorded this financial year, suggesting balanced activity. Compared to Greater Sydney, Seven Hills shows comparable construction activity per person, preserving market equilibrium. New development consists of 69.0% detached houses and 31.0% townhouses or apartments, marking a shift from the current 84.0% houses pattern.

This suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. With around 222 people per dwelling approval, Seven Hills is characterized as a low density area. Future projections estimate an addition of 1,787 residents by 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
