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, AreaSearch utilises NSW State Government's SA2 level projections released in 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. Future population trends indicate a decline overall, with the suburb's population expected to reduce by 287 persons by 2041 according to this methodology. However, specific age cohorts are anticipated to grow, notably the 75 to 84 age group, projected to increase by 596 people over this period.

AreaSearch assessment of residential development drivers sees a low level of activity in Plumpton, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers allocated from statistical area data indicates Plumpton averaged around 16 new dwelling approvals per year over the past five financial years, totalling an estimated 84 homes. As of FY-26 so far, 11 approvals have been recorded. The area's population decline suggests new supply has likely kept up with demand, offering good choice to buyers. New homes are being built at an average expected construction cost value of $254,000, below the regional average, indicating more affordable housing options for buyers.

This financial year, $949,000 in commercial approvals have been registered, suggesting minimal commercial development activity. Compared to Greater Sydney, Plumpton has around two-thirds the rate of new dwelling approvals per person and places among the 28th percentile nationally, implying somewhat limited buyer options while strengthening demand for established properties. This activity is lower than the national average, reflecting market maturity and possible development constraints. Recent development has been entirely comprised of detached houses, maintaining Plumpton's traditional suburban character focused on family homes appealing to those seeking space.

Interestingly, developers are building more traditional houses than the current mix suggests (82.0% at Census), indicating continued strong demand for family homes despite density pressures. The location has approximately 580 people per dwelling approval, demonstrating an established market. With population expected to remain stable or decline, Plumpton should see reduced pressure on housing, potentially creating opportunities for buyers.
