Interesting but I think you indicate how you chose 'England's major cities'. I would have expected Portsmouth / Southampton or Bradford to be included.
Thanks Glenn, and apologies for the slow response. We used the 9 largest cities in England, measured in terms of the population living in the primary urban area: http://www.centreforcities.org/puas/
