In 2007, the population of the Manchester local government district was estimated to be 458,100, whilst the surrounding Metropolitan County of Greater Manchester had an estimated population of 2,562,200. Forming part of the English Core Cities Group, often described as the second city of the UK, and the "Capital of the North", Manchester today is a centre of the arts, the media, higher education and commerce. In a poll of British business leaders published in 2006, Manchester was regarded as the best place in the UK to locate a business. Manchester was the host of the 2002 Commonwealth Games, and among its other sporting connections are its two Premier League football teams, Manchester City and Manchester United. Historically, most of the city was a part of Lancashire, with areas south of the River Mersey being in Cheshire. Manchester was the world's first industrialised city and played a central role during the Industrial Revolution. Manchester City Centre is now on a tentative list of UNESCO World Heritage Sites, mainly due to the network of canals and mills constructed during its 19th-century development. (Full article...)
