Cultural diversity

Language used at home

About this topic

Language used at home shows which languages people speak in their home life and whether English or another language is used most often. It is a key indicator of cultural diversity and language retention within communities.

This topic is useful for planning communication, multicultural services, and local engagement. It should be analysed together with proficiency in English and birthplace, because language alone does not show migration history or support needs.

Interpretation notes

  • The Census records the language used most often at home, so it does not capture every language a person can speak.
  • Language used at home is not a measure of English proficiency, literacy, or migration history on its own.
