Population
Boulder is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends
Based on analysis of Australian Bureau of Statistics (ABS) population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Boulder's population is estimated at around 5,255 as of Nov 2025. This reflects an increase of 383 people (7.9%) since the 2021 Census, which reported a population of 4,872 people. The change is inferred from the resident population of 5,244, estimated by AreaSearch following examination of the latest Estimated Resident Population data release by the ABS in June 2024 and an additional 10 validated new addresses since the Census date. This level of population equates to a density ratio of 1,194 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Boulder's 7.9% growth since the 2021 census exceeded that of the SA4 region (7.6%) and the SA3 area, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by natural growth which contributed approximately 55.00000000000001% of overall population gains during recent periods.
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, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). As we examine future population trends, a population increase just below the median of non-metropolitan areas nationally is expected. The suburb is expected to grow by 341 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 6.5% in total over the 17 years.

Development
Residential development activity is lower than average in Boulder according to AreaSearch's national comparison of local real estate markets
AreaSearch analysis of ABS building approval numbers shows Boulder had around 5 residential properties approved annually. Between FY-21 and FY-25, approximately 27 homes were approved, with none yet in FY-26. This results in an average of 8.3 new residents per year arriving per dwelling constructed over the past five financial years.
Supply is substantially lagging demand, indicating heightened buyer competition and pricing pressures. New dwellings are developed at an average value of $538,000, slightly above the regional average, suggesting a focus on quality developments. This financial year has seen $2.0 million in commercial approvals, reflecting a predominantly residential focus. Compared to Rest of WA, Boulder records about 65% of building activity per person and places among the 17th percentile nationally, offering limited choices for buyers and supporting demand for existing dwellings. This level is below average nationally, indicating the area's maturity and possible planning constraints.
New building activity comprises 67.0% standalone homes and 33.0% medium and high-density housing, expanding affordable compact alternatives. Boulder has around 949 people per approval, showing a mature, established area. Future projections estimate Boulder adding 341 residents by 2041. If current construction levels persist, housing supply may lag population growth, intensifying buyer competition and underpinning price growth.

As of June 2025, 2,661 residents are employed, with an unemployment rate of 3.8% compared to Rest of WA's 3.2%. Workforce participation stands at 62.2%, slightly higher than Rest of WA's 59.4%. Key industries include mining, retail trade, and accommodation & food services. Mining is a significant employer, with an employment share 2.4 times the regional level.
Conversely, agriculture, forestry & fishing employs just 0.1% of local workers, lower than Rest of WA's 9.3%. The area offers limited local employment opportunities, as indicated by the difference between Census working population and resident population. Over the year to June 2025, labour force levels decreased by 2.7%, with employment down 3.4%, leading to a 0.6 percentage point rise in unemployment rate. In contrast, Rest of WA saw employment growth of 1.1% and labour force growth of 0.5%, with unemployment falling by 0.6 percentage points. Jobs and Skills Australia's national employment forecasts from Sep-22 suggest potential future demand within Boulder. National employment is forecast to grow by 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between sectors. Applying these projections to Boulder's employment mix indicates local employment could increase by 4.9% over five years and 11.3% over ten years.
