Outer London is the name for the group of London boroughs that form a ring around Inner London. Together, the inner and outer boroughs form London, the capital city of the United Kingdom. These were areas that were not part of the County of London and became formally part of Greater London in 1965. An exception is North Woolwich, which was in the County of London but was transferred to Newham.
The twenty Outer London boroughs were defined by the London Government Act 1963. The main difference between Inner and Outer London boroughs between 1965 and 1990 was that the outer boroughs were local education authorities. The statutory Outer London boroughs are: Barking and Dagenham, Barnet, Bexley, Brent, Bromley, Croydon, Ealing, Enfield, Haringey, Harrow, Havering, Hillingdon, Hounslow, Kingston upon Thames, Merton, Newham, Redbridge, Richmond upon Thames, Sutton, Waltham Forest.
