Question(s) from the Census form

What is the address of this dwelling?

Where does the person usually live?

How this variable is created

The data is mainly captured from mark‑box responses on the form. If the indicator boxes are left blank but a usual address is provided, UAICP is derived from the address reported. Data may also be derived from relationship information on the form that shows the person is a visitor. 

History and changes

A question relating to usual residence was first asked in the 1971 Census and has been asked at every Census since. 

In 2026, address labels were updated to reflect the change in year.
