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

CLTHP is based on responses to the long-term health conditions question and records the number of selected conditions reported.

Individuals who mark only 'Any other long-term health condition(s)' are classified as having 'None of the selected conditions'. If they select a listed condition along with 'Any other long-term health condition(s)', they are counted under the relevant category.

Respondents reporting more than three conditions are grouped into 'Three or more conditions'.

History and changes

This variable was first introduced in the 2021 Census.

In 2026, 'Liver disease' was added as a health condition to the question, and the instructional text for mental health condition was updated.
