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. Anticipating future population dynamics, a population increase just below the median of statistical areas analysed by AreaSearch is expected, with the area expected to increase by 740 persons by 2041 based on the latest annual ERP population numbers, reflecting an increase of 6.4% in total over the 17 years.

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

Harrington Park has averaged around 13 new dwelling approvals per year, with 66 homes approved over the past 5 financial years (between FY-21 and FY-25) and 2 so far in FY-26. With an average of 2.6 new residents per year gained for each dwelling built over the past 5 financial years (between FY-21 and FY-25), suggesting solid demand that supports property values, new homes are being built at an average value of $404,000. Additionally, $50,000 in commercial development approvals have been recorded this financial year, demonstrating the area's residential nature.

When measured against Greater Sydney, Harrington Park records markedly lower building activity (74.0% below regional average per person). This scarcity of new homes typically strengthens demand and prices for existing properties. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. Further, new construction has been completely comprised of detached dwellings, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. With around 2468 people per dwelling approval, Harrington Park reflects a highly mature market.

Population forecasts indicate Harrington Park will gain 737 residents through to 2041 (from the latest AreaSearch quarterly estimate). Building activity is keeping pace with growth projections, though buyers may experience heightened competition as the population grows.

As of December 2025, 7,479 residents are in work while the unemployment rate is 2.6% below Greater Sydney's rate of 4.2%, and workforce participation is well beyond standard (83.6% compared to Greater Sydney's 70.2%).

Employment among residents is concentrated in construction, health care & social assistance, and retail trade. The area demonstrates a particularly notable concentration in construction, with employment levels at 1.5 times the regional average. Meanwhile, professional & technical services have a limited presence with 6.0% employment compared to 11.5% regionally. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, over the 12 months to December 2025, employment increased by 6.9% while the labour force increased by 7.2%, causing the unemployment rate to rise by 0.2 percentage points. By comparison, Greater Sydney recorded employment growth of 2.2%, labour force growth of 2.3%, with unemployment rising marginally. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Harrington Park. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Harrington Park's employment mix suggests local employment should increase by 6.2% over five years and 12.9% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
