Bradford is a city in West Yorkshire, England. It became a municipal borough in 1847, received a city charter in 1897 and, since the 1974 reform, the city status has belonged to the larger City of Bradford metropolitan borough.
It had a population of 349,561 at the 2011 census, making it the second-largest subdivision of the West Yorkshire Built-up Area after Leeds, which is approximately 9 miles (14 km) to the east. The borough had a population of 552,644, making it the 9th most populous district in England.
Historically part of the West Riding of Yorkshire, the city grew in 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”; this in turn gave rise to the nicknames “Woolopolis” and “Wool City”.
