The population of South Wentworthville was estimated at around 7,237 as of Feb 2026, reflecting an increase of 324 people since the 2021 Census which reported a population of 6,913. This change is inferred from AreaSearch's estimation of the resident population at 7,187 following examination of ABS's latest ERP data release in June 2024 and an additional 39 validated new addresses since the Census date. The suburb's population density ratio was 3,998 persons per square kilometer, placing it in the top 10% of national locations assessed by AreaSearch. Over the past decade, South Wentworthville demonstrated a compound annual growth rate of 1.7%, outpacing Greater Sydney's growth. Overseas migration contributed approximately 64.0% of overall population gains during recent periods. AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with 2022 as the base year, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with 2021 as the base year.

Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population trends indicate a population increase just below the median of statistical areas across the nation, with South Wentworthville expected to increase by 855 persons to 2041 based on aggregated SA2-level projections, reflecting an overall increase of 11.1% over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, South Wentworthville has averaged approximately 48 new dwelling approvals each year over the past five financial years. This totals an estimated 243 homes. So far in FY-26, 16 approvals have been recorded. On average, 1.6 new residents per year per dwelling constructed were seen between FY-21 and FY-25.

However, this figure has increased to 7.5 people per dwelling over the past two financial years, indicating growing popularity of the area and potential supply constraints. New homes are being built at an average expected construction cost value of $453,000. The new development consists of 24.0% detached dwellings and 76.0% townhouses or apartments, reflecting a shift from the area's existing housing composition (currently 57.0% houses). This indicates decreasing availability of developable sites and changing lifestyles requiring more diverse, affordable housing options.

South Wentworthville has approximately 465 people per dwelling approval, reflecting an established area. According to AreaSearch's latest quarterly estimate, the location is expected to grow by 805 residents through to 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.
