# List of UK city regions by population

This is a list of city regions in the United Kingdom by population, area and population density. They consist of Combined authorities and combined county authorities in England, and regional city deals in Scotland and in Wales. Data is gathered by the Office for National Statistics (ONS).
Despite the terminology, which is also used by the ONS, the city regions are established on the basis of local devolution deals, which results in also less populated areas being included within this list, whilst some other major cities in the UK might be excluded. The list also does not delineate metropolitan or urban areas, which are separate concepts.

### New deals since 2022

The North East Combined Authority did not exist in 2022, it is the result of a merger between the earlier non-mayoral North East Combined Authority and the North of Tyne Combined Authority, however it is included due to data for 2022 being available. In addition, new local devolution deals have been established since 2022, and they are not included in the table above. These city regions are:
* East Midlands CCA, comprising Nottinghamshire and Derbyshire (including Nottingham and Derby unitary authorities), with a population of 2 230 289.
