Based on analysis of Australian Bureau of Statistics (ABS) population updates for South Wentworthville and new addresses validated by AreaSearch, the suburb's population is estimated at around 7,250 as of November 2025. This reflects an increase of 337 people (4.9%) since the 2021 Census, which reported a population of 6,913 people.

This level of population equates to a density ratio of 4,005 persons per square kilometer, placing South Wentworthville in the top 10% of national locations assessed by AreaSearch. Over the past decade, South Wentworthville has demonstrated resilient growth patterns with a compound annual growth rate of 1.6%, outpacing the metropolitan area. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 64.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each Statistical Area Level 2 (SA2) area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch utilises 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. Examining future population trends, a population increase just below the median of statistical areas across the nation is expected in South Wentworthville, with the suburb expected to increase by 877 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 12.1% in total over the 17 years.

Residential development activity is slightly higher than average within South Wentworthville when compared nationally

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, South Wentworthville averaged approximately 49 new dwelling approvals annually over the past five financial years. This totals an estimated 248 homes. As of FY-26, 7 approvals have been recorded. On average, each dwelling constructed has accommodated around 1.5 new residents per year between FY-21 and FY-25.

However, this figure increased to 4.5 people per dwelling over the past two financial years, reflecting South Wentworthville's growing popularity and potential supply constraints. New homes are being built at an average expected construction cost of $450,000, aligning with broader regional development trends. The new developments consist of 25% detached dwellings and 75% townhouses or apartments, indicating a shift from the area's existing housing composition, which is currently 57% houses. This change suggests decreasing availability of developable sites and reflects evolving lifestyles and demand for more diverse, affordable housing options.

South Wentworthville has approximately 272 people per dwelling approval, indicating a low-density market. According to AreaSearch's latest quarterly estimate, the area is projected to grow by 878 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing favorable conditions for buyers and potentially supporting population growth beyond current projections.
