The remaining two-thirds of the electorate in west-central Maidstone were reunited with the town wards that had been lost in 1983 to Mid Kent (which was abolished), as well as joined by a rural part of the Weald to the south of the town, previously in the Tunbridge Wells constituency.

Most of the electorate live in urban Maidstone, which has some light industry but whose economy is increasingly dominated by the service sector (including care, hospitality and insurance).
