Counties in England bearing the "-shire" suffix comprise: Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire, Cheshire, Derbyshire, Gloucestershire, Hampshire, Herefordshire, Hertfordshire, Huntingdonshire, Lancashire, Lincolnshire, Leicestershire, Northamptonshire, Nottinghamshire, Oxfordshire, Shropshire, Staffordshire, Warwickshire, Wiltshire, Worcestershire and Yorkshire. These counties, on their historical boundaries, cover a little more than half the area of England. The counties that do not use "-shire" are mainly in three areas, in the south-east, south-west and far north of England. Several of these counties no longer exist as administrative units, or have had their administrative boundaries reduced by local government reforms. Several of the successor authorities retain the "-shire" county names, such as West Yorkshire and South Gloucestershire.
