Suburb profile
Mount Barker Summit is a semi-rural locality near Adelaide, in Mount Barker Council. It is close to Mount Barker and the mountain.
Working from home is an exceptional strength, with working from home 115% above the peer median, and population growth is a very strong feature of the suburb, with population growth 82% above the peer median, and socio-economic advantage sits well above the peer median, well above typical levels for semi-rural and lifestyle localities. Space is a strength, but car dependence is high. The main trade-offs are higher recorded crash rates relative to resident population and thinner mapped green cover within the suburb boundary, with recorded road crashes 113% above the peer median.
Mount Barker Summit is a better fit for people who value socio-economic advantage.

ABS Estimated Resident Population allocated to this suburb from SA2-level data. Not an official ABS suburb count.
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 (~100), extrapolated at +1.5% average annual growth since 2011. It is illustrative only — not an official ABS forecast.

Australian Taxation Office Taxation Statistics 2023–24, individuals Table 25. Figures describe taxpayers who live in postcode 5251 — not a suburb-level official statistic. Rental investment is the share of local taxpayers reporting rental income or loss, not the share of local properties owned by investors.
Percentiles rank this postcode among unique postcodes in SA, so suburbs that share a postcode are not counted twice. Dollar figures are compared with Australia-wide ATO medians from the same release. Median net rent is among taxpayers who reported the rent label and can be negative.

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).
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.
