Overview
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.
Westminster Parliamentary constituencies
Areas used to elect a member of parliament (MP) to the House of Commons. Once elected, the MP will represent their constituency in the House of Commons.
Electoral wards and divisions
Areas used to elect local authority councillors.
The data are for wards as at May 2022, apart from two instances.
We treat the City of London and the Isles of Scilly local authorities as single wards, not made up of multiple wards.
We have also split the data for Hunmanby and Sherburn ward into Hunmanby and Sherburn (part Ryedale) and Hunmanby and Sherburn (part Scarborough). This is to reflect that the ward is split between two local authorities, Ryedale and Scarborough.
Parishes
In England, a civil parish is a type of administrative parish used for local government. This geographical designation represents the lowest tier of local government. Wales was also divided into civil parishes until 1974, when they were replaced by communities. These are similar to English parishes in the way they operate.
Senedd electoral regions
There are five Senedd electoral regions each made up of between seven and nine Senedd constituencies.
