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 based on answers to the long‑term health conditions question. It identifies people who have certain combinations of health conditions, known as comorbidities.

People who select both ‘Lung condition (including COPD or emphysema)’ and ‘Mental health condition (including depression or anxiety)’ are coded to ‘Has lung condition and mental health condition’. Respondents may have other long‑term health conditions, but those are not captured in this variable. All other response combinations, including ‘No long-term health condition’, are coded to ‘Does not have lung condition and mental health condition’.

If a person has more than one specified combination of long‑term health conditions, they are included in each relevant comorbidity health variable.

History and changes

This was a new variable in 2021. 

In 2026, additional instructional text relating to mental health was included in the question.
