It has a two-tier local government, with a county council based in Matlock and eight district councils. Apart from 13 towns with between 10,000 and 100,000 inhabitants, there is a large amount of sparsely populated agricultural upland: 75% of the population live in 25% of the area. Although Derbyshire is generally considered to be in the East Midlands, some parts, such as High Peak, are closer to the northern cities of Manchester and Sheffield and the people there overwhelmingly think of themselves as being northerners.
Before 1998 the county included the city of Derby. Derby is now a unitary authority, but remains part of Derbyshire for ceremonial purposes.
Derbyshire was traditionally divided into six hundreds, namely Appletree , High Peak, Morleyston and Litchurch , Repton and Gresley , Scarsdale , Wirksworth . These were based on the seven earlier wapentakes recorded in the Domesday Book, with the merging of Repton and Gresley wapentakes.
Derbyshire had a detached part in north-western Leicestershire, surrounding Measham and Donisthorpe. This escaped regularisation in 1844, and was incorporated into Leicestershire in 1888 when the county councils were set up. The thin strip of Leicestershire between the exclave and Derbyshire, containing Overseal and Netherseal , is now considered part of Derbyshire.
