Greater Manchester, England's second most populous metropolitan area, has a population of over 2.7 million people, making it the third most populous county in England. The Greater Manchester Urban Area includes Bolton, Oldham, Rochdale, Stockport, Tameside and Wigan as well as the city of Manchester, itself. Yet, despite a large population, residents don’t feel overwhelmed: The average population density of Greater Manchester is just 27,571 per square mile. By comparison, London averages more than 10 times that amount.
