St Agnes is a middle-ring metropolitan suburb of Adelaide, in Tea Tree Gully Council. It is mainly residential, with little in the way of a distinct commercial centre or landmark identity.
Everyday destinations are relatively walkable, well above typical levels for middle-ring metropolitan suburbs. School access, parks and housing affordability are all relative strengths. Recorded road-crash rates are lower than in comparable places, with recorded road crashes 50% below the peer median, and green cover is an exceptional strength. The main trade-offs are more mapped flood cover and weaker population growth, with population growth 39% below the peer median.
St Agnes's appeal is better explained by housing, access and location than by a strong standalone precinct or destination.

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 (~4,350), extrapolated at +0.6% 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.
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.
