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 Birmingham and the larger West Midlands conurbation, which is the third most populous in the United Kingdom. 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. The region also contains 6 shire counties which stretch from the Welsh Border to the East Midlands.
The region is geographically diverse, from the urban central areas of the conurbation to the rural western counties of Shropshire and Herefordshire which border Wales. The longest river in the UK, the River Severn, traverses the region southeastwards, flowing through the county towns of Shrewsbury and Worcester, and the Ironbridge Gorge, a UNESCO World Heritage Site. Staffordshire is home to the industrialised Potteries conurbation, including the city of Stoke-on-Trent, and the Staffordshire Moorlands area, which borders the southeastern Peak District National Park near Leek. The region also encompasses five Areas of Outstanding Natural Beauty, the Wye Valley, Shropshire Hills, Cannock Chase, Malvern Hills, and parts of the Cotswolds. Warwickshire is home to the towns of Stratford upon Avon, birthplace of writer William Shakespeare, Rugby, the birthplace of Rugby football and Nuneaton, birthplace to author George Eliot.
