PURPOSE AND DEFINITION The concept of a Primary Urban Area was created in an attempt to enable economic and social comparisons between cities using definitions less arbitrary than the administrative boundaries of Local Authorities , but avoiding one problem of using the Urban Areas defined by the Office For National Statistics - that sprawling Conurbation s such as the West Yorkshire Urban Area , containing multiple distinct settlements with large degrees of physical and social independence, but that happen to touch, end up being treated as if they were a single city. Frequently asked questions about the state of the English cities Department for Communities and Local Government (see "''What is a Primary Urban Area (PUA)?''") To enable this, Primary Urban Areas are defined as being based on areas of continuous built-up land containing urban structures that are within 50 metres of each other, Primary Urban Areas (PUAS) State of the Cities - Making sense of cities, Department for Communities and Local Government while Urban Areas only require that urban land uses should be less than 200 metres apart. Key Statistics for Urban Areas in England and Wales Office for National Statistics Census 2001 (definition on page 8 of pdf) In addition, to qualify as a Primary Urban Area a built-up area must have a population in excess of 125,000. On this basis England had 56 Primary Urban Areas in 2007. As Primary Urban Areas were created to allow statistical comparisons, and the majority of statistics are produced based on Administrative or Electoral geographies, Primary Urban Areas are approximated to Local Authority and Ward level, or to an additional measure called a ''tract'' - similar in size to a ward but designed to be subject to fewer revisions over time. It is for these approximate areas that statistics are available. Wards and tracts, being smaller, allow a greater degree of precision in comparing PUAs, but using local authority-based definitions allow PUA comparisons to be made using the wider range of statistics available at this level.Robinson, Phillipa " Presenting Statistics on UK Geographies ", State of the Cities Database, Presentation to North East Regional Information Partnership Primary Urban Areas are designed purely as a tool of statistical analysis and aren't intended to form definitive measures of cities for policy purposes Frequently asked questions about the state of the English cities Department for Communities and Local Government (see "''What is a Primary Urban Area (PUA)?''"), and are named after the largest settlement within. ISSUES WITH PRIMARY URBAN AREAS Primary Urban Areas still suffer to a certain extent from containing multiple distinct settlements with large degrees of independence, but that happen to touch being treated as if they were a single city. A good example of this is within the Birmingham PUA, where ) displays a complex pattern of interdependance both within the area and to the two cities, making statistical separation of the area extremely difficult Department of Communities and Local Government English City-Regions based on labour and housing markets. As Primary Urban Areas are related to administrative areas, they can also contain rural areas, or have parts of the Urban Area excluded from the relevant PUA. The Leeds PUA is an example of the former, where the City Of Leeds local authority area that is contained within the PUA includes a wide rural area in addition to the urban cores; whilst the Manchester PUA does not contain Wilmslow which is a part of the Greater Manchester Urban Area but outside the agglomerated local authorities that make up the PUA.
