Question(s) from the Census form

Has the person been told by a doctor or nurse that they have any of these long-term health conditions?

How this variable is created

This variable is derived from responses to the long-term health conditions question and aims to capture people who have specific combinations of health conditions (known as comorbidity).

Where a respondent selects ‘Arthritis’ and ‘Asthma’ they are coded to '1 Has arthritis and asthma’. The respondent could also have other long-term health conditions, but those conditions are not recorded in this variable. All other combinations of responses, including ‘No long-term health condition’ are coded to '2 Does not have arthritis and asthma’.

If a person has more than one specified combination of long-term health conditions, they will be captured in more than one comorbidity health variable.

History and changes

This is a new variable for 2021.

Data use considerations

Long-term health conditions data from Census is not intended to provide prevalence estimates. Prevalence estimates of long-term health conditions should be sourced from the National Health Survey (NHS) or National Aboriginal and Torres Strait Islander Health Survey (NATSIHS).

If a person has more than one specified combination, they will be captured in more than one comorbidity health variable.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form. For the item non-response rate for the health question, see CLTHP.
