England has 51 officially designated cities (as of 2024)—but "city status" is a formal honor, not a demographic or administrative category.
Since the Local Government Act 1972, "city" has no administrative function. Local government units are: district, borough, city (borough), metropolitan borough, unitary authority, London borough. A "city council" may govern a district/borough with city status (e.g., City of Canterbury, City of Winchester).
Bath, Birmingham, Bradford, Brighton & Hove, Bristol, Cambridge, Canterbury, Carlisle, Chelmsford, Chester, Chichester, Colchester, Coventry, Derby, Doncaster, Durham, Ely, Exeter, Gloucester, Hereford, Hull, Lancaster, Leeds, Leicester, Lichfield, Lincoln, Liverpool, London (City of London + Westminster), Manchester, Milton Keynes, Newcastle upon Tyne, Norwich, Nottingham, Oxford, Peterborough, Plymouth, Portsmouth, Preston, Ripon, Salford, Salisbury, Sheffield, Southampton, St Albans, Stoke-on-Trent, Sunderland, Truro, Wakefield, Wells, Winchester, Wolverhampton, Worcester, York.
London is unique: the City of London (square mile) and City of Westminster are separate cities within Greater London.
