2 named roads through this area carry OpenStreetMap's highest classification - a freeway, motorway or major highway, whatever the road is called locally, alongside 5 named main roads. Roads are counted by name, not by mapped segment. Where a home sits relative to them matters far more than the count - a street two blocks back can be quiet.

The suburbs in this area
Everything else on this page is published for Boulder as a whole - one ABS statistical area covering 3 separate gazetted suburbs. These are the figures published for each of those suburbs on its own.
| Suburb | Residents Census 2021 | Schools |
|---|---|---|
| Boulder | 4,872 | 3 |
| South Boulder | 1,506 | 0 |
| Victory Heights | 772 | 0 |
Each row is that suburb's own published figure - nothing here is the wider area's number divided up. Resident counts are the Census 2021 usual-resident count for the gazetted suburb, so they will not add up to the population at the top of this page, which is the ABS's later June 2025 estimate for the whole statistical area: a different measure on a different date. Schools are ACARA-registered schools whose published address falls inside the suburb boundary, which is not the same as the school your address is zoned to. No free source publishes suburb-level house medians in Western Australia, so no price column is shown - that is our coverage gap, not a statement about the market here. Every other figure on this page - crime & safety, overlays, commute, amenities, projections, the Family-Fit score - is published for the whole statistical area and cannot be separated by suburb.
