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

The population of the suburb of Seven Hills (NSW) is estimated to be around 21,312 as of Feb 2026. This reflects an increase of 1,217 people since the 2021 Census, which reported a population of 20,095 people. The change is inferred from the resident population of 20,687 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 210 validated new addresses since the Census date. This level of population equates to a density ratio of 2,208 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Seven Hills's growth rate of 6.1% since the census positions it within 1.1 percentage points of the SA3 area (7.2%), demonstrating competitive growth fundamentals. Population growth for the suburb was primarily driven by overseas migration, contributing approximately 67.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Looking at population projections moving forward, a population increase just below the median of Australian statistical areas is expected in the suburb of Seven Hills (NSW), with an expected increase of 2,026 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 6.6% in total over the 17 years.

Residential development activity is slightly higher than average within Seven Hills when compared nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Seven Hills recorded approximately 110 residential properties granted approval each year over the past five financial years, totalling an estimated 554 homes. As of FY-26, 56 approvals have been recorded. On average, between FY-21 and FY-25, 0.4 new residents arrived per new home built. This indicates that new construction is matching or outpacing demand, offering buyers more options while supporting population growth.

The average value of new homes being built is $401,000. Additionally, $14.4 million in commercial development approvals have been recorded this financial year, suggesting balanced commercial development activity. Relative to Greater Sydney, Seven Hills shows comparable construction activity per person, preserving market equilibrium consistent with surrounding areas. New development consists of 69.0% detached houses and 31.0% townhouses or apartments, marking a significant departure from existing housing patterns (currently 84.0% houses).

This shift suggests diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. With around 222 people per dwelling approval, Seven Hills shows characteristics of a low density area. Future projections show Seven Hills adding 1,401 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

However, professional & technical services had limited presence with 8.4% employment compared to 11.5% regionally. Many residents commute elsewhere for work based on Census working population counts. Between December 2024 and December 2025, employment levels increased by 3.3%, labour force grew by 2.7%, leading to a 0.6 percentage point drop in unemployment rate. In contrast, Greater Sydney saw employment growth of 2.2% with marginal labour force increase. Jobs and Skills Australia's national employment forecasts from May-25 project a 6.6% expansion over five years and 13.7% over ten years. Applying these projections to Seven Hills' employment mix suggests local employment should increase by 6.6% over five years and 13.8% over ten years, though this is a simple weighting extrapolation for illustrative purposes only.
