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. It counts the number of people who marked ‘Diabetes (excluding gestational diabetes)’ on the form.

History and changes

This is a new variable for 2021.

Data use considerations

The Census Health question does not distinguish between type 1 and type 2 diabetes. Therefore, this variable will include respondents reporting both forms of diabetes.

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

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