Avon /ˈeɪvən/ was, from 1974 to 1996, a non-metropolitan and ceremonial county in the west of England. The county was named after the River Avon, which runs through the area. It was formed from parts of the historic counties of Gloucestershire and Somerset, together with the City of Bristol. In 1996, the county was abolished and the area split between four new unitary authorities: Bath and North East Somerset, Bristol, North Somerset and South Gloucestershire. The Avon name is still used for some purposes. The area had a population of approximately 1.08 million people in 2009.
