How this variable is created
This variable is derived from the questions asking for a person's place of usual residence on Census Night and one year ago. From this data it is possible to identify the change of address of people and show the movement of households for one year prior to the Census date. The dwelling can then be coded as having all, some, or no residents in the household having a different address one year ago.
Dwellings where at least one resident aged one year and over did not state their address one year ago are coded to ‘& At least one resident did not state an address one year ago’.

In 2021, the reference year has been updated. The ‘Not stated’ category label has also been updated to ‘At least one resident did not state an address one year ago’.
