AreaSearch uses 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 (released in 2022 with a base year of 2021) are used. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future trends suggest a population increase just below the median nationally, with an expected growth of 762 persons to 2041 based on latest annual ERP numbers, reflecting a total gain of 9.8% over the 16-year period.

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

South Wentworthville averaged approximately 56 new dwelling approvals per year. Between FY-21 and FY-25284 homes were approved, with an additional 33 approved in FY-26 to date.

Over the past five financial years, an average of 1.1 new residents arrived per new home built. This suggests a balance between supply and demand, contributing to stable market dynamics. The average construction cost for new properties was $224,000, which is below the regional average, indicating more affordable housing options. Compared to Greater Sydney, South Wentworthville has similar development levels per person, maintaining market balance with the broader area. However, building activity has slowed in recent years.

Currently, 26.0% of new dwellings are detached houses, while 74.0% are townhouses or apartments. This shift towards compact living provides affordable entry pathways and attracts downsizers, investors, and first-time purchasers. This represents a significant change from the current housing mix, which is 62.0% houses. South Wentworthville has approximately 252 people per dwelling approval, indicating characteristics of a low-density area. According to AreaSearch's latest quarterly estimate, South Wentworthville is projected to gain 756 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.

As of December 2025, 3,644 residents were employed while the unemployment rate was 3.7% higher than Greater Sydney's rate of 4.2%, indicating room for improvement. Workforce participation was somewhat below standard at 63.9% compared to Greater Sydney's 68.8%. According to Census responses, 38.3% of residents worked from home, potentially impacted by Covid-19 lockdowns. Leading employment industries were health care & social assistance, construction, and retail trade.

Construction had notable concentration with employment levels at 1.3 times the regional average. Professional & technical services had limited presence with 7.5% employment compared to 11.5% regionally. The area appeared to offer limited local employment opportunities based on Census working population vs resident population comparison. Between December 2024 and December 2025, employment levels increased by 3.9%, labour force grew by 4.2%, resulting in a 0.3 percentage point rise in unemployment. In contrast, Greater Sydney saw employment rise by 2.2%, labour force grow by 2.3%, with marginal unemployment increase. Jobs and Skills Australia's national employment forecasts from May-25 estimated national employment growth at 6.6% over five years and 13.7% over ten years. Applying these projections to South Wentworthville's employment mix suggested local employment should increase by 6.6% over five years and 13.6% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
