Dean Park

Dean Park is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of Nov 2025, the estimated population of Dean Park is around 3,231 people. This figure reflects an increase of 51 individuals since the 2021 Census, which reported a population of 3,180 people. The change is inferred from AreaSearch's estimation of the resident population at 3,232 following examination of the latest ERP data release by the ABS in June 2024 and an additional 8 validated new addresses since the Census date. This results in a population density ratio of 2,139 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Dean Park's growth rate of 1.6% since the census positions it competitively with other SA3 areas, being within 1.5 percentage points of their growth rate of 3.1%. Overseas migration contributed approximately 55.00000000000001% of overall population gains during recent periods in the suburb of Dean Park.

AreaSearch adopts 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. By 2041, the suburb of Dean Park is expected to experience a population increase just below the median of statistical areas across the nation. Based on aggregated SA2-level projections, the area is anticipated to expand by approximately 290 persons over this period, reflecting an overall increase of around 8.0%.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Dean Park has received around 10 dwelling approvals per year over the past five financial years. This totals an estimated 54 homes. As of FY-26, 9 approvals have been recorded. The area's population decline suggests new supply is meeting demand, providing good buyer choice while offering more affordable housing options with average construction values at $324,000, below the regional average.

This financial year has seen $9.2 million in commercial approvals, indicating limited commercial development focus. Compared to Greater Sydney, Dean Park's construction levels are 31.0% above the regional average per person over the past five years, balancing buyer choice with support for current property values. Nationally, however, this is below average, reflecting the area's maturity and possible planning constraints. New development consists of 85.0% detached houses and 15.0% attached dwellings, maintaining Dean Park's traditional suburban character focused on family homes.

The location has approximately 338 people per dwelling approval, indicating a low density market. Future projections estimate Dean Park will add 257 residents by 2041 based on the latest AreaSearch quarterly estimate. Current development patterns suggest new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
