This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

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 ABS population updates and AreaSearch validation, Boulder's population was estimated at 5,265 as of Feb 2026. This reflected an increase of 393 people since the 2021 Census, which reported a population of 4,872. The change was inferred from AreaSearch's estimate of 5,255 residents following examination of ABS ERP data release in June 2024 and validation of nine new addresses since the Census date. This resulted in a density ratio of 1,196 persons per square kilometer, comparable to averages seen across locations assessed by AreaSearch. Boulder's growth of 8.1% since the 2021 census exceeded the SA3 area's growth of 7.7%. Natural growth contributed approximately 55.00000000000001% of overall population gains during recent periods.
AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and post-2032 estimations, AreaSearch used growth rates by age cohort provided by the ABS in its Greater Capital Region projections released in 2023, based on 2022 data. Future population trends suggest a median increase for non-metropolitan areas nationally, with Boulder expected to grow by 342 persons to 2041, reflecting an overall increase of 6.2% 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 shows Boulder granted around 5 residential approvals annually. Between FY-21 and FY-25, approximately 26 homes were approved, with none so far in FY-26. This results in an average of 8.6 new residents per year per dwelling constructed over the past five financial years.
Supply is lagging demand, indicating heightened buyer competition and pricing pressures. Developers target the premium market segment, with new dwellings valued at an average of $538,000. In FY-26, $2.0 million in commercial approvals have been registered, suggesting a predominantly residential focus. Compared to Rest of WA, Boulder records about 63% of building activity per person and ranks among the 16th percentile nationally, indicating limited choices for buyers and supporting demand for existing dwellings. This level reflects the area's maturity and possible planning constraints.
New building activity comprises 60.0% standalone homes and 40.0% medium and high-density housing, expanding affordable options. Boulder has around 1043 people per approval, indicating a mature, established area. Future projections estimate Boulder to add 328 residents by 2041. If current construction levels persist, housing supply may lag population growth, intensifying buyer competition and underpinning price growth.

Employment
While Boulder retains a healthy unemployment rate of 4.0%, recent employment declines have impacted its national performance ranking
Boulder has a diverse workforce with both white and blue collar jobs, notably in manufacturing and industrial sectors. Its unemployment rate is 4.0%, indicating relative employment stability over the past year (AreaSearch data). As of September 2025, 2,746 residents are employed, with an unemployment rate at 3.3% above Rest of WA's rate.
Workforce participation stands at 69.8%. Census responses show that only 2.4% of residents work from home. Key industries for employment among residents are mining, retail trade, and accommodation & food services. Mining is particularly prominent, employing 2.4 times the regional level.
However, agriculture, forestry & fishing employs just 0.1% of local workers, below Rest of WA's 9.3%. Over the year to September 2025, labour force levels increased by 0.6%, while employment decreased by 0.3%, leading to an unemployment rate rise of 0.8 percentage points (AreaSearch analysis). Jobs and Skills Australia forecasts national employment growth at 6.6% over five years and 13.7% over ten years. Applying these projections to Boulder's employment mix suggests local employment should increase by 4.9% over five years and 11.3% over ten years, though this is a simplified extrapolation for illustrative purposes only.
