Derby (i/ˈdɑrbi/ DAR-bi in Received Pronunciation, but often locally /ˈdɑrbɛ/ DAR-beh) is a city and unitary authority area in the East Midlands region of England. It lies upon the banks of the River Derwent in the south of the county of Derbyshire, of which it is the county town. In the 2011 census, the city had a population of 248,700 and 1,543,000 in the wider metro area.
As home to Lombe's Mill, the first factory in the world, Derby is considered a birthplace of the Industrial Revolution. With the arrival of the railways in the 19th century, and due to its strategic central location, the city grew to become a foremost centre of the British rail industry.
Today, Derby is an internationally renowned centre for advanced transport manufacturing, home to the world’s second largest aero-engine manufacturer, Rolls-Royce, and Derby Litchurch Lane Works—the UK's only remaining train manufacturer. The Toyota Manufacturing UK's automobile headquarters is found just south of the city at Burnaston.
