The county has an area of 1,663 km (642 square miles) and had an estimated population of 1,248,649 in 2024. The north of the county, which includes the towns of Staines-upon-Thames and Epsom, is densely populated and forms part of the Greater London conurbation. A second conurbation along the western border of the county includes Camberley and Farnham and extends into Hampshire and Berkshire. Woking is located in the north-west, and Guildford in the centre-west. The south of the county is rural, and its largest settlements are Horley in the south-east and Godalming in the south-west.
