How this variable is created

This variable is derived from the overseas born indicator (OBIP) variable, which indicates whether a person was born overseas or in Australia.  

Households are grouped into different categories based on the countries of birth of their members: 

  • Households are classified as an ‘Overseas born household’ if at least one member of the household is born overseas.  
  • Households are classified as ‘Australian born household’ if all members of the household were born in Australia. 
  • Households are classified as ‘Partially stated Australian born household’ when there is a combination of household members who were born in Australia, and at least one household member did not state birthplace or was coded to 'Inadequately described'.    
  • Households are classified as ‘Not stated’ households when all household members did not state their birthplace or were coded to 'Inadequately described'.
