South East England

Constituent counties

The region is made up of nine traditional counties and unitary areas. These include Berkshire, Buckinghamshire, East Sussex, Hampshire, the Isle of Wight, Kent, Oxfordshire, Surrey and West Sussex. The Isle of Wight is the region's principal island and has a distinct local identity.

Geography and landscape

The landscape ranges from chalk downland and rolling hills to river valleys and long stretches of coastline on the English Channel and the Thames estuary. The region's highest natural point is Walbury Hill in Berkshire (about 297 m). Much of the area is rural, but large urban concentrations occur along the coast and on corridors leading into London.

Population, towns and economy

In the early 21st century the region had a population of roughly eight million people, making it one of the most populous parts of England outside London. Major urban centres include Brighton and Hove, Portsmouth, Southampton and Reading, alongside many commuter towns that form part of the Greater London urban area. The economy mixes advanced services, manufacturing, maritime industries, tourism and agriculture.

History and development

Administratively the region was established for planning and statistical purposes in the 1990s, though its towns and counties have much older histories stretching back to Roman, Saxon and medieval periods. Historic ports, market towns and university cities such as those in Oxfordshire and Kent have shaped the cultural landscape.

Notable facts and distinctions

• Proximity to London makes parts of the region important commuter and high‑technology corridors.
• The coastline supports ferry links, naval bases and seaside tourism, notably around the Solent and Sussex coast.
• Natural features include chalk downland, areas of outstanding natural beauty and the island ecology of the Isle of Wight.
