An assessment of population growth drivers in Winthrop reveals an overall ranking slightly below national averages considering recent, and medium term trends

Winthrop's population was 6,020 people as of Aug 2021. By Jun 2024, it had increased to 6,526, a rise of 506 people (8.4%). This growth is attributed to an estimated resident population from ABS and four new validated addresses since the Census date. The population density was 1,875 persons per square kilometer. Winthrop's growth rate of 8.4% since census is close to the national average of 8.6%. Overseas migration contributed approximately 84.6% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered, growth rates by age cohort from ABS's Greater Capital Region projections (released in 2023, based on 2022 data) are used. Future trends project above median population growth for the area, with an expected increase of 1,278 persons to 2041, a total gain of 19.6%.

Residential development activity is lower than average in Winthrop according to AreaSearch's national comparison of local real estate markets

Winthrop averaged approximately five new dwelling approvals annually. The Australian Bureau of Statistics produces development approval data on a financial year basis, totalling 27 approvals across the past five financial years from FY-21 to FY-25, with one approval so far in FY-26. An average of 15.6 new residents per year has been associated with every home built over these five financial years.

This supply is substantially lagging demand, leading to heightened buyer competition and pricing pressures. New homes are being constructed at an average expected cost of $626,000, indicating a focus on the premium segment with upmarket properties. Compared to Greater Perth, Winthrop has significantly less development activity, 86.0% below the regional average per person, which typically reinforces demand and pricing for existing dwellings. This is also lower than nationally, reflecting market maturity and possible development constraints. All new construction in Winthrop has been comprised of detached dwellings, sustaining its suburban identity with a concentration of family homes suited to buyers seeking space.

With around 1344 people per approval, Winthrop shows a mature, established area. Future projections indicate Winthrop adding 1,278 residents by 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.

This compares favourably to the national unemployment rate of 4.5% but lags behind national employment growth of 0.26%. Jobs and Skills Australia's national employment forecasts from May 2025 suggest that Winthrop's employment could grow by approximately 6.7% over five years and 13.8% over ten years, based on a simple weighting extrapolation of industry-specific projections against the local employment mix.
