Primary Urban Areas
Date: 01/01/2010Unless otherwise stated, Centre for Cities uses data for Primary Urban Areas (PUA) in its analysis – a measure of the "built-up" area of a city, rather than individual local authority districts. PUA data only exists for English cities. For Welsh and Scottish cities, we use the corresponding local authority area, with the exception of tightlybounded Glasgow, where we have defined the city as an aggregate of five local authorities. Belfast has been defined as the aggregate of Belfast City, Carrickfergus, Castlereagh, Lisburn, Newtownabbey and North Down.
