The suburb's 11.4% growth since the 2021 census exceeded the state average of 7.1%. Population growth was primarily driven by overseas migration, contributing approximately 79.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas for years 2032 to 2041. Considering projected demographic shifts, Wentworthville is forecast to experience significant population growth, with an expected increase of 4,323 persons by 2041 based on aggregated SA2-level projections, reflecting a gain of 25.2% in total over the 16 years.

As of FY-26, there have been 33 approvals recorded. This results in an average of about 4.2 new residents per year per dwelling constructed between FY-21 and FY-25.

Employment opportunities locally may be limited, as indicated by the count of Census working population versus resident population.

In comparison, Greater Sydney recorded employment growth of 2.2%. Jobs and Skills Australia's national employment forecasts from May-25 suggest that national employment should expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Wentworthville's employment mix suggests local employment should increase by 7.1% over five years and 14.5% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
