Editing Metropolitan area (section)

=== United Kingdom ===
The [[United Kingdom]]'s [[Office for National Statistics]] defines "[[travel to work area]]s" as areas where "at least 75% of an area's resident workforce work in the area and at least 75% of the people who work in the area also live in the area".<ref>[http://www.ons.gov.uk/ons/guide-method/geography/beginner-s-guide/other/travel-to-work-areas/index.html Beginners' guide to UK geography - Travel to Work Areas (TTWAs)] Office for National Statistics</ref> The [[European Union]]'s [[ESPON]] group has compiled a separate [[ESPON metropolitan areas in the United Kingdom|list of metropolitan areas]] which covers the UK. Industrial and housing growth in the United Kingdom during the 19th and early 20th centuries produced many conurbations. [[Greater London]] is by far the largest urban area and is usually counted as a conurbation in statistical terms, but differs from the others in the degree to which it is focused on a single central area. In the mid-1950s the [[Metropolitan Green Belt|Green Belt]] was introduced to stem the further urbanisation of the countryside in [[South East England]]. The list below shows the most populous urban areas in the UK as defined by the [[Office for National Statistics]] (ONS). Different organisations define conurbations in the UK differently for example, [[Liverpool–Manchester Megalopolis|the Liverpool–Manchester or the Manchester–Liverpool conurbation]] is defined as one conurbation by [[AESOP]] in a comparison report published by the [[University of Manchester]] in 2005 found here. The Liverpool–Manchester Conurbation has a population of 5.68 million.
