Derbyshire (i/ˈdɑrbɨʃə/ DAR-bi-shər or /ˈdɑrbɪʃɪər/ DAR-bi-sheer; abbreviated Derbys. or Derbs.) is a county in the East Midlands of England. A substantial portion of the Peak District National Park lies within Derbyshire. The southern extremity of the Pennine range of hills extends into the north of the county. The county contains within its boundary of approximately 225 miles part of the National Forest. It borders on Greater Manchester to the northwest, West Yorkshire to the north, South Yorkshire to the northeast, Nottinghamshire to the east, Leicestershire to the southeast, Staffordshire to the west and southwest and Cheshire also to the west. In 2003 the Ordnance Survey placed Church Flatts farm, near Coton in the Elms, as the furthest point from the sea in Great Britain.
The city of Derby is now a unitary authority area, but remains part of the ceremonial county of Derbyshire. The non-metropolitan county contains 30 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.
