How this variable is created

This variable is created from usual address indicator (UAICP), Indigenous status (INGP) and family composition (FMCF). It is created by identifying whether at least one person in a family is: 

  • Aboriginal and/or Torres Strait Islander  
  • Counted at home on Census night 

Categories are derived in the following way, using responses to INGP: 

‘Family with Aboriginal and/or Torres Strait Islander person(s)’: 

  • all persons in the household identify as ‘Aboriginal and/or Torres Strait Islander’; or 
  • at least one person in the household identifies as ‘Aboriginal and/or Torres Strait Islander’. Other household members have a 'Not stated' or 'Non-Indigenous' Indigenous status 

‘Families with non-Indigenous persons only’: 

  • all persons in the household have a 'Non-Indigenous' Indigenous status; and 
  • no person in the household identifies as ‘Aboriginal and/or Torres Strait Islander’; and 
  • no person in the household has a 'Not stated' Indigenous status 

‘Families with an Indigenous status not stated’ 

  • all persons in the household have a 'Not stated' Indigenous status; or 
  • at least one person in the household has a 'Not stated' Indigenous status. Other household members have a 'Non-Indigenous' Indigenous status.
  • no person in the household identifies as ‘Aboriginal and/or Torres Strait Islander’. 

Persons temporarily absent are excluded from this variable. 

History and changes

This variable was introduced in 2021.  

In 2026, categories were updated to separate families with non-Indigenous persons only from families with persons where Indigenous status was ‘Not stated’. Updates to the output category labels were made to reflect this and a new category of ‘Families with an Indigenous status not stated’ was added.
