The UK government introduced the concept of a primary urban area as a defining characteristic for substantial settlements, using the shorthand term 'city' for them, whether or not they had formal city status. In reality, a PUA may contain multiple settlements, even multiple cities. It should not be confused with 'urban areas' or 'built-up areas' that are more rigorously defined by the Office for National Statisticsor even city status.
Historically, the boundaries of cities within England and the United Kingdom as a whole have remained largely undefined, leading to difficulties in comparisons between them. However, a definitive list of cities in the United Kingdom, which in itself would constitute a type of definition known as an Extensional definition (specifically, an enumerative definition) does exist,Department of Constitutional Affairs webpage defining cities. Retrieval Date: 22 July 2007 though it does not define the limits of these cities. To allow such comparisons to be made the Office of the Deputy Prime Minister, in conjunction with other Government departments, began compiling reports and a database to allow comparison of the English cities. This report is known as the State of the English Cities Report and was maintained by the Department for Communities and Local Government.
Using this definition the term "city" is used as a primary urban area, which is distinct from the Office for National Statistics urban area agglomerations, with a total population in excess of 125,000. The population figures are based on the cumulative total population of the constituent wards. This list is not the same as the list of local authorities which have been granted city status and is intended to define the physical extent of the largest urban centres. These are available from the State of the Cities Database.
However, some controversy arose when using these terms, for example the Manchester PUA contains the City of Manchester and also includes that of the City of Salford which is a metropolitan borough and has held city status since 1926. The inclusion of the City of Wolverhampton and the Black Country in the Birmingham PUA also led to a meeting of the West Midlands group of MPs where their displeasure was made clear to David Miliband, then the minister in charge. This inclusion of Wolverhampton demonstrates differences between PUAs and the Eurostat equivalent, where Wolverhampton has its own larger urban zone.
