Coding rules 

To determine whether a person’s need for assistance in one or more of the three core activity areas is due to a long-term health condition, disability or old age, the Census form asks: 'What are the reasons for the need for assistance or supervision?'

A person is coded to ‘Has need for assistance with core activities’ if they report one or more of the following: 

  • long-term health condition (lasting six months or more) 
  • disability (lasting six months or more)

A person is coded to ‘Does not have need for assistance with core activities’ if the reported reasons are limited to the following: 

  • no need for assistance 
  • short-term health condition (lasting less than six months) 
  • difficulty with English language 
  • other reason

If ‘Old or young age’ is the only reported reason, the person is coded: 

  • ‘Does not have need for assistance with core activities’ if aged under 40 years 
  • ‘Has need for assistance with core activities’ if aged 40 years or over

History and changes

A question about core activity need for assistance was first asked in the 2006 Census to measure disability across different areas and groups in Australia.  

There have been no changes for the 2026 Census.
