Suburb Score

Around the national middle

A socio-economic measure from ABS Census data — not a measure of how good a suburb is to live in or visit. How we calculate this.

Is St Agnes (SA) a good place to live?

There’s no single answer — it depends on what matters to you. So instead of one mystery number, we break it down: a transparent score on each part of life we can back with public data, and an honest “not yet” on the parts we can’t.

Below the national middle on the data we score

A weighted blend of the 2 components we can score for St Agnes (SA) from public data. It sits alongside — and reconciles with — the socio-economic Suburb Score above; it is a transparent read, not a complete verdict.

Not yet scored

We’d rather leave these open than publish a number we can’t stand behind. Here’s where each one stands.

  • Amenities & accessNot scored yet — our OpenStreetMap amenity mapping is still rolling out across suburbs.
  • Green spaceNot scored yet — our OpenStreetMap green-space mapping is still rolling out across suburbs.
  • TransportNot scored yet — our OpenStreetMap public-transport mapping is still rolling out across suburbs.
  • SchoolsNot scored yet — school performance (ACARA / ICSEA) needs a data-reuse licence cleared before we can publish it.
  • SafetyNot scored yet — Australia has no single open crime dataset and safety data carries defamation and legal care, so it is gated pending a go/no-go and will be data-only when added.
  • CommunityNot scored yet — we won't reduce community to a number from a proxy. We'd rather leave it open than publish an invented value judgement.

A transparent read on public data, not a verdict — and not a measure of any person or community. See our methodology for how each component is worked out and why some aren’t scored yet.
