The East Midlands is one of nine official regions of England at the first level of NUTS for statistical purposes. It consists of Derbyshire, Leicestershire, Lincolnshire (except North and North East Lincolnshire), Northamptonshire, Nottinghamshire and Rutland.
The region has an area of 15,627 km2 (6,034 sq mi), with a population over 4.5 million in 2011. The most populous settlements in the region are Derby, Leicester, Lincoln, Mansfield, Northampton and Nottingham. Other notable settlements include Boston, Chesterfield, Corby, Grantham, Hinckley, Kettering, Loughborough, Newark-on-Trent, Skegness, Wellingborough, and Worksop.
Relative proximity to London and its position on the national motorway and trunk road networks help the East Midlands to thrive as an economic hub. Nottingham and Leicester are each classified as a sufficiency-level world city by the Globalization and World Cities Research Network.[2]
The region is primarily served by East Midlands Airport, which lies between Derby, Loughborough and Nottingham.
