List of urban areas in the United Kingdom

This is a list of the most populous urban areas in the United Kingdom based on the 2011 census, as defined by the Office for National Statistics (ONS). 
==Definition==
The methodology used by ONS in 2011 is set out in 2011 Built-up Areas – Methodology and Guidance, published in June 2013. When ONS reported the results of the 2011 UK census, it used the term "built-up area" rather than the term "urban area" as used in previous censuses.
