With 8,42 mio. inhabitants, London is Europe’s most populous city and one of the "command centres" for the global economy. It comprises 33 local authorities – the 32 London boroughs and the City of London Corporation. Together, they form the Greater London area.
The City, or Square Mile, is at the heart of London. It is the world leader in international finance and business services. Around 400.000 people are employed here, joining its resident population of around 9.000, with more than 98% of businesses being small or medium sized enterprises. Its main business sectors are professional, scientific and technical (42%), finance and insurance (17%) and business administration and support services (9%).
The City of London Corporation, which looks after the Square Mile, has three main aims – to support and promote the City; to provide high quality local and policing services; and to provide valued services to London and the nation as a whole.
