Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Country of birth (extended)

For people not born in one of the four countries of the UK or the Republic of Ireland, there was an option to select "elsewhere".

People who selected "elsewhere" were asked to write in the current name for their country of birth.

This classification provides additional detail on write-in responses.

Passports held

Where a person recorded having more than one passport, they were counted only once, categorised in the following priority order: 1. UK passport, 2. Irish passport, 3. Other passport.
