Adelaide suburbs where the most Korean is spoken at home

Hectorville has the highest share, at 1.8% of residents. Tranmere and Adelaide follow.

This page ranks Adelaide suburbs by the share of residents who speak Korean at home in the 2021 Census — where the Korean-speaking community is most concentrated. Only suburbs with at least 2,000 residents are ranked.

Shares are the count of Adelaide residents who speak Korean at home divided by the suburb's total population, from the ABS 2021 Census language table — the same source as each suburb page's language breakdown. Percentile ranks are computed within Adelaide's pool. Language spoken at home understates a community's full size — it misses Korean-heritage residents who speak mainly English at home — but it's the cleanest signal of an active community. Descriptive demographic information, not a recommendation.

How we ranked these

100% share of residents who speak this language at home in the 2021 Census (speakers divided by the suburb's total population), percentile-ranked within Adelaide's candidate pool. Only suburbs with at least 2,000 residents qualify, and the larger absolute number of speakers breaks ties. Language spoken at home understates a community's full size but is the cleanest signal of an active community. Descriptive ABS Census data, not a recommendation.

Common questions about this ranking

Which Adelaide suburbs have the most Korean spoken at home?

Hectorville has the highest share, at 1.8% of residents. Tranmere and Adelaide follow.

How is this ranking put together?

Each Adelaide suburb is ranked by the share of its residents who speak Korean at home in the 2021 Census — that count divided by the suburb's total population. Only suburbs with at least 2,000 residents are included, and percentile ranks are computed within Adelaide's pool, so the list reflects concentration relative to other metro suburbs.

Where does the data come from?

The Australian Bureau of Statistics 2021 Census 'language used at home' question — the same source as the language breakdown on each suburb page. Nothing is estimated or inferred about any individual.

Does this capture everyone of Korean heritage?

No — it counts people who speak Korean at home, which understates the full community: Korean-heritage residents who speak mainly English at home aren't counted. It's the cleanest available signal of an active language community, not a complete ancestry measure, and it isn't a recommendation to seek out or avoid anywhere.

How current is it?

The figures are from the 2021 Census, the most recent available until results from the August 2026 Census are released in 2027. The top 15 is recomputed whenever we refresh the census data.
