Inner London.

About Inner London

Inner London is the group of London boroughs that form the interior part of Greater London and are surrounded by Outer London. With its origins in the bills of mortality, it became fixed as an area for statistics in 1847 and was used as an area of local government from 1855 to 1965 principally as the County of London or earlier as the Metropolitan Board of Works Area (metropolis). It now has two common definitions. The first is the statutory definition delineated in the London Government Act 1963, coming into force on 1 April 1965, comprising twelve Inner London boroughs and almost identical to the County of London that was abolished at the same time. The second is the definition used by the Office for National Statistics comprising eleven of the statutory Inner London boroughs and two of the statutory Outer London boroughs, as well as the City of London.
