How this variable is created

This variable contains the response category answer to the question 'Where did the person usually live one year ago (at 10 August 2020)?'. The responses are captured automatically from mark box responses on the form.

Where the indicator mark boxes have been left blank by a respondent, but they have reported an address one year ago, UAI1P is derived based on the address reported. If the respondent does not report either the indicator or the address, they will be set to 'Not stated'. However, where a person who is aged under 16 years (i.e. they were aged under 15 years one year ago) does not respond to the usual address one year ago question, but their parent(s) did respond, their UAI1P is set to the same value as their parent.

History and changes

The question relating to the usual address one year ago was first asked in the 1976 Census and has been asked at every Census since.

In 2021, the categories with years have been updated to 2021 and the previous year of 2020.
