The West Midlands is one of nine official regions of England at the first level of NUTS for statistical purposes. It covers the western half of the area traditionally known as the Midlands. It contains the second most populous British city, Birmingham, and the larger West Midlands conurbation, which includes the city of Wolverhampton and large towns of Dudley, Solihull, Walsall and West Bromwich. The city of Coventry is also located within the West Midlands county, but is separated from the conurbation to the west by several miles of green belt.
