This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may 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 AreaSearch's analysis, Boulder's population is around 7,722 as of Nov 2025. This reflects an increase of 572 people (8.0%) since the 2021 Census, which reported a population of 7,150 people. The change is inferred from the estimated resident population of 7,705 from the ABS as of June 2024 and an additional 9 validated new addresses since the Census date. This level of population equates to a density ratio of 589 persons per square kilometer. Boulder's 8.0% growth since the 2021 census exceeded the SA4 region (7.6%) and the SA3 area, marking it as a growth leader in the region. Population growth for the area was primarily driven by natural growth that contributed approximately 54.8% 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). Considering the projected demographic shifts, a population increase just below the median of national non-metropolitan areas is expected. The area is expected to expand by 530 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 6.6% 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
Boulder has experienced approximately five dwelling approvals annually over the past five financial years, totalling 29 homes. As of FY-26, there have been zero approvals recorded to date. On average, around 10.8 new residents arrive per year for each dwelling constructed between FY-21 and FY-25. This indicates a significant demand exceeding supply, which typically leads to price growth and increased buyer competition.
The average construction cost value of new homes is $425,000, suggesting developers focus on the premium market with high-end developments. In this financial year, $2.0 million in commercial approvals have been registered, indicating minimal commercial development activity compared to the rest of WA. Boulder has 53.0% less development activity per person than the regional average and is also below the national average, reflecting its mature area status and potential planning constraints. New developments consist of 60.0% standalone homes and 40.0% attached dwellings, offering a mix of medium-density options across various price brackets. This marks a change from the current housing mix, which is predominantly houses (85.0%). The estimated population per dwelling approval in Boulder is 2306 people, indicating a quiet development environment.
According to AreaSearch's latest quarterly estimate, Boulder is expected to grow by 513 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.

Employment
Employment conditions in Boulder remain below the national average according to AreaSearch analysis
Boulder has a balanced workforce with representation across white and blue collar jobs. Manufacturing and industrial sectors are prominent.
Unemployment rate is 3.9%. Employment stability over the past year is relative. As of September 2025, 3,975 residents are employed while unemployment rate is 4.5%, slightly higher than Rest of WA's 3.3%. Workforce participation is similar to Rest of WA's 59.4%.
Leading industries include mining, retail trade, and accommodation & food services. Mining employment share is 2.5 times the regional level at 10.7% while agriculture, forestry & fishing is under-represented at 0.4%, compared to Rest of WA's 9.3%. Employment opportunities locally appear limited based on Census data comparison. From September 2024 to September 2025, employment levels remained stable (0.0%) while labour force increased by 0.8%, causing unemployment rate to rise by 0.8 percentage points. In contrast, Rest of WA saw employment rise by 1.4% and unemployment fall by 0.2%. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Boulder's industry mix suggests local employment should increase by 4.8% over five years and 11.2% over ten years, though this is a simplified extrapolation for illustrative purposes only.
