Am I Really a Londoner?

The London identity dispute. My friends tell me I can't really claim 'Londoner' status, but London has never had one universally accepted boundary. This map sets five competing definitions against each other: administrative, historical, postal, urban and commuter. Toggle the layers in the feature list. Any judgement on London / not London is entirely my own ;)

A history of London boundaries

• 1889 - the County of London is created, carved from Middlesex, Surrey and Kent. Much smaller than today's capital (Layer B).
• 1965 - the London Government Act 1963 creates Greater London: the County of London and Middlesex are abolished, and territory is absorbed from Surrey, Kent, Essex and Hertfordshire (Layer C). Middlesex's edges escape: Potters Bar to Hertfordshire, Staines and Sunbury to Surrey.
• 1969 - the largest later tweaks: Farleigh goes to Surrey, Knockholt to Kent.
• Postal London (Layer E), the continuous built-up area (Layer D) and the commuter rail map (Layer F) each draw a different London. None matches the red line.

The Londoner Legitimacy Test (open any burgundy pin in The Disputed Places) Computed from the map's own layers - Greater London membership, historic county, built-up area, post town, rail link and straight-line distance from Charing Cross - then given a verdict. Note, this is not a scientific or official assessment of identity.
