Essex is a county located northeast of London, part of the East of Englandregion. Because of its proximity to London and the economic magnetism which that city exerts, many of Essex's settlements function as dormitory towns[?] or villages where London workers raise their families.
The name of the county is derived from an ancient Anglo-Saxon kingdom called Essex.
The districts of Southend-on-Sea and Thurrock are now unitary authority areas separate from Essex. The Lakeside shopping centre at Thurrock was one of England's first out-of-town shopping centres; it remains popular despite congestion on the nearby M25 motorway and competition from newer, more glamorous destinations.
Essex also contains Stansted Airport and several smaller aerodromes that have evolved from bomber or fighter bases constructed during the Second World War.
