AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising 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. As we examine future population trends, projections indicate a decline in overall population, with the suburb's population expected to shrink by 300 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to expand by 601 people.

In contrast, commercial development activity in Plumpton has been minimal this financial year, with $949,000 in approvals registered. Compared to Greater Sydney, Plumpton records about 64% of the building activity per person and ranks among the 28th percentile nationally, suggesting more limited housing choices for buyers and supporting demand for existing homes. This lower-than-average activity reflects the area's maturity and potential planning constraints.

New construction in Plumpton has been exclusively detached houses, maintaining its traditional suburban character with a focus on family homes appealing to those seeking space. Developers are building more traditional houses than the current mix suggests, indicating continued strong demand for family homes despite density pressures. With around 579 people per dwelling approval, Plumpton reflects a highly mature market. Given stable or declining population projections, housing demand pressures in Plumpton should reduce, benefiting potential buyers.
