This figure represents an increase of 44 individuals since the 2021 Census, which reported a population of 3,124 people in the suburb.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, the SA State Government's Regional/LGA projections by age category are used, based on 2021 data and adjusted employing weighted aggregation methods. By 2041, Trott Park is projected to increase its population by approximately 141 persons, reflecting a total growth of 5.7% over the 17-year period, as per aggregated SA2-level projections. This growth rate is just below the median of statistical areas analysed by AreaSearch.

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

AreaSearch analysis of ABS building approval numbers shows Trott Park has had around 4 new homes approved annually on average over the past five financial years from FY-21 to FY-25, totalling approximately 24 homes. So far in FY-26, 1 approval has been recorded. Each dwelling built has resulted in an average of 2.4 new residents per year, reflecting strong demand that supports property values. New homes are being constructed at an average cost of $536,000, indicating a focus on the premium segment with upmarket properties.

This financial year has seen $1.8 million in commercial approvals, suggesting minimal commercial development activity. Compared to Greater Adelaide, Trott Park shows significantly reduced construction levels, at 79.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties. The area's building activity is also below national averages, reflecting its maturity and possible planning constraints. Recent building activity consists entirely of detached houses, preserving Trott Park's suburban nature with an emphasis on detached housing attracting space-seeking buyers.

As of now, there are approximately 2129 people per dwelling approval in the location, demonstrating an established market. According to AreaSearch's latest quarterly estimate, Trott Park is expected to grow by 180 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
