London boroughs

The London boroughs are 32 of the districts that make up the administrative area of Greater London, England. The current London boroughs were all created on 1 April 1965, at the same time as Greater London, by merging groups of former local government units. Twelve were designated as Inner London boroughs and twenty as Outer London boroughs. The London boroughs have populations of between 150,000 and 400,000. Inner London boroughs tend to be smaller, in both population and area, and more densely populated than Outer London boroughs. Minor adjustments have been made to borough boundaries and two have changed their names. The City of London, at the historic core of London, is the 33rd area for local government and is not a London borough.
