Description

This method returns Census 2021 estimates that classify usual residents in England and Wales by their use of a second address, and whether the second address is inside or outside the UK.

Second address is an address (in or out of the UK) a person stays at for more than 30 days per year that is not their place of usual residence. Second addresses typically include:

armed forces bases
addresses used by people working away from home
a student's home address
the address of another parent or guardian
a holiday home

If a person with a second address was staying there on census night, they were classed as a visitor to the second address but counted as a usual resident at their home address.

“Second address indicator” is split into 4 categories including total.

The estimates are as at Census Day, 21 March 2021.
