Suburb profile

Trinity Gardens is an inner metropolitan suburb of Adelaide, in Norwood Payneham and St Peters Council. It is primarily residential, without a particularly distinct commercial centre or landmark identity.

Employment is stronger than in comparable places, with employment 11% above the peer median. School access is strong, with school access 50% above the peer median. Population growth is stronger than in comparable places, with population growth 16% above the peer median. Space is a strength, but car dependence is high. The clearer weaknesses are limited amenity for the price and higher recorded crash rates relative to resident population.

Trinity Gardens's appeal is better explained by housing, access and location than by a strong standalone precinct or destination.

Generated from the official metrics on this page. It can omit nuance or contain errors — check the tables and source notes before relying on it.

ABS Estimated Resident Population allocated to this suburb from SA2-level data. Not an official ABS suburb count.

Methodology

Figures are allocated from ABS Estimated Resident Population at Statistical Area Level 2 (SA2), using 2021 Census share within overlapping SA2 regions. Where Census data is unavailable, area overlap is used instead.

The dashed chart line is a simple growth-trend estimate to June 2030 (~1,450), extrapolated at +0.9% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Federal electorate from AEC federal division boundaries (2025 redistribution). Division-level results are official AEC figures from the latest general election, with by-election updates where applicable. The estimated suburb profile blends up to eight nearest ordinary polling booths in the same electorate using inverse-distance weighting from the suburb centroid — an approximation, not official AEC data. Nearest polling places are shown for reference.

Socio-economic

IRSAD decile (2021)
9/10
IRSD decile (2021)
8/10

ABS Socio-Economic Indexes for Areas (SEIFA), 2021 release — the latest available, derived from the 2021 Census. Deciles rank suburbs nationally from 1 (lowest) to 10 (highest).

What do IRSAD and IRSD measure?

IRSAD — Index of Relative Socio-economic Advantage and Disadvantage. Combines indicators of advantage (e.g. high income, skilled occupations) and disadvantage. Higher decile = more advantaged relative to other Australian areas.

IRSD — Index of Relative Socio-economic Disadvantage. Focuses on disadvantage only (e.g. low income, unemployment, limited education). Higher decile = less disadvantage nationally.

A new SEIFA edition typically follows each census; the ABS has not announced a release date beyond 2021.
