Bradford is in the Metropolitan Borough of the City of Bradford in West Yorkshire, England, in the foothills of the Pennines west of Leeds, and northwest of Wakefield. Bradford became a municipal borough in 1847, and received its charter as a city in 1897. Following local government reform in 1974, city status was bestowed upon the wider metropolitan borough. Bradford forms part of the West Yorkshire Urban Area conurbation which in 2001 had a population of 1.5 million and it is the fourth largest urban area in the United Kingdom with the Bradford subdivision of the aforementioned urban area having a population of 528,155. 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 areas access to a supply of coal, iron ore and soft water facilitated the growth of Bradfords manufacturing base, which, as textile manufacture grew, led to an explosion in population and was a stimulus to civic investment; Bradford has a large amount of listed Victorian architecture including the grand Italianate City Hall. The textile sector in Bradford fell into decline from the mid-20th century. Since this time, Bradford has emerged as a tourist destination, becoming the first UNESCO City of Film with attractions such as the National Science and Media Museum, Bradford City Park, the Alhambra theatre and Cartwright Hall. However, Bradford has faced similar challenges to the rest of the post-industrial area of Northern England, including deindustrialisation, social unrest and economic deprivation.
