Inner London is the name for the group of London boroughs which form the interior part of Greater London and are surrounded by Outer London. The area was first officially defined in 1965 and for purposes such as statistics, the definition has changed over time. The terms Inner London and Central London cannot be used interchangeably to mean the same area. Inner London is officially the richest area in Europe with the most expensive street in Europe, GDP per capita is nearly $80,000 while the UK GDP per capita is nearly $46,000. Many of the world's richest people live in West and North London, but there is widespread poverty too in these areas as well as the East End and areas south of the river.
The area covered by the London postal district is sometimes referred to as 'Inner London'. However it is not coterminous with other definitions of Inner London as its area is somewhat larger and covers 624 km2 (241 sq. miles). A small part of the London Borough of Lewisham falls outside its boundaries whilst 44 of its 119 districts are in Outer London and its irregular shape stretches to the Greater London boundary at Scratch Wood and beyond it at Sewardstone.
From 1990 to 2000 London used two separate telephone dialling codes with one code designated for Inner London, however the area covered by this code was widely different from all of the above definitions and most of Greater London is now covered by a single 020 dialling code.
The term can also be used in a variety of other contexts with different meanings.
