Cultural diversity
Ancestry
About this topic
Ancestry describes a person's cultural association and ethnic background, and Census respondents can report more than one ancestry. It is a broader cultural measure than country of birth because it can reflect family heritage across generations.
This topic helps show the size and diversity of cultural groups in an area, including groups whose members were born in Australia. Because multiple ancestries can be reported, ancestry totals can exceed the total population, so it is best read with birthplace, language used at home, and religion.
Interpretation notes
- People can report up to two ancestries, so category totals represent responses rather than a single unduplicated person count.
- ABS advises that ancestry is best used with birthplace and language, because ancestry alone is a broad measure of ethnicity and cultural background.
- The 2021 form added separate Aboriginal and Torres Strait Islander mark boxes, so those categories need caution in over-time comparison.
Key insight
