Bradford is a city in West Yorkshire, England. It lies amongst the Pennines, 8.6 miles (13.8 km) west of Leeds, and 13 miles (20.9 km) northwest of Wakefield. Bradford is surrounded by several smaller settlements which together form the metropolitan borough of the City of Bradford, Bradford being the administrative centre. Bradford has a population of 293,717, whilst the wider borough has a population of 493,100. Historically a part of the West Riding of Yorkshire, Bradford rose to prominence during the 19th century as an international centre of textile manufacture, particularly wool. It was a boomtown of the Industrial Revolution, and amongst the earliest industrialised settlements, rapidly becoming the "wool capital of the world". The area's supply of coal, iron ore and soft water facilitated the growth of Bradford's manufacturing base, which, as textile manufacture grew, led to an explosion in population size and a stimulation in civic investment; Bradford has fine Victorian architecture including the grande Italianate City Hall. Bradford became a municipal borough in 1847, and received its charter as a city in 1897. Following a boundary reform in 1974, city status was transferred to the wider metropolitan district. The textile sector in Bradford fell into a terminal decline from the mid-20th century. Since this time, Bradford has faced similar challenges to the post-industrial north, including deindustrialisation, economic deprivation and housing issues. Since the 1950s Bradford has experienced significant levels of immigration, particularly from India and Pakistan, and subsequently has the fourth highest proportion of Muslims in England and Wales. Since the decline in heavy industry, Bradford has emerged as a tourist destination with attractions such as the National Media Museum, Cartwright Hall, and Saltaire, the latter of which is a World Heritage Site.
