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 Seven Hills (NSW) statistical area (Lv2) is estimated at approximately 21,271 as of November 2025. This figure represents an increase of 1,176 people since the 2021 Census, which reported a population of 20,095. The change was inferred from AreaSearch's estimation of the resident population at 20,687 in June 2024 and the validation of 210 new addresses since the Census date. This results in a population density ratio of 2,204 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. The Seven Hills (NSW) (SA2)'s growth rate of 5.9% since the census is within 1.2 percentage points of the SA3 area's 7.1%, indicating strong growth fundamentals. Overseas migration contributed approximately 67.0% of overall population gains during recent periods in this area.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in June 2024 with a base year of 2022. For areas not covered by this data, AreaSearch uses the NSW State Government's SA2 level projections released in December 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, population projections indicate an increase just below the median of Australian statistical areas by 2041. The Seven Hills (NSW) (SA2) is expected to gain approximately 2,056 persons by 2041, reflecting a total growth of 7.0% over the 17-year period.

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

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, totalling an estimated 554 homes. As of FY26, 53 approvals have been recorded. On average, 0.3 new residents per year arrive for every new home built between FY21 and FY25. This suggests 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 $400,000. In commercial development, $14.4 million in approvals have been recorded this financial year, indicating balanced activity. Compared to Greater Sydney, Seven Hills has comparable construction activity per person, maintaining market equilibrium with surrounding areas. New development consists of 69% detached houses and 31% townhouses or apartments, marking a shift from the current 84% houses, likely due to diminishing developable land availability and evolving lifestyle preferences.

With around 221 people per dwelling approval, Seven Hills is considered a low-density area. According to AreaSearch's latest quarterly estimate, Seven Hills is projected to add 1,497 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.
