In addition to Stockport proper, the metropolitan borough includes the urban built-up area of Cheadle, the towns of Bramhall, Romiley, and Marple, and areas of open countryside.

Granted a charter in 1220, the original settlement stood on the southern slope of a narrow gorge where the Rivers Tame and Goyt meet to form the Mersey; the modern borough has spread over the more level higher ground. Cotton spinning was Stockport’s staple industry in the 19th century, and hat making dated from the 18th century. Diversification brought industries ranging from electronics to heavy engineering, plastics, and food processing.
