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.

Post-2019 Westminster Parliamentary constituencies

Areas that will be used to elect members of parliament (MPs) to the House of Commons for the next general election. The boundaries for these areas are provisional and subject to confirmation, and will replace the constituency boundaries present for the 2019 General Election. Once elected, each MP will represent their constituency in the House of Commons.
