The home counties are the counties of England that surround London (although several of them do not border it). The counties generally included in the list are Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, and Sussex. Other counties more distant from London—such as Bedfordshire, Cambridgeshire, Hampshire and Oxfordshire—are also sometimes regarded as home counties due to their proximity to London and their connection to the London regional economy.
The origin of the term "home counties" is unknown and no exact definition exists, making their composition a matter of constant debate.
The earliest use of the term cited in the Oxford English Dictionary is from 1695. Charles Davenant, in An essay upon ways and means of supplying the war, wrote, "The Eleven Home Counties, which are thought in Land Taxes to pay more than their proportion, viz. Surry [sic] with Southwark, Hertfordshire, Bedfordshire, Cambridgshire, Kent, Essex, Norfolk, and Suffolk, Berks, Bucks, and Oxfordshire."
Later definitions have tended to be more narrow and Bacon's Large Scale Atlas of London and Suburbs (revised edition c. 1912) includes Berkshire, Buckingham, Essex, Hertford, Kent, Middlesex and Surrey in the "maps of the home counties".
