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. According to the 2021 census, the city itself had a population of 352,317, making it the second-largest subdivision of the West Yorkshire Built-up Area after Leeds, which is approximately 9Â km (5.6Â mi)) to the east. The wider metropolitan borough had a population of 546,976 at the same census, making it one of the most populous districts 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". Lying in the eastern foothills of the Pennines, the area's access to supplies of coal, iron ore and soft water facilitated the growth of a manufacturing base, which, as textile manufacture grew, led to an explosion in population and was a stimulus to civic investment. There is a large amount of listed Victorian architecture in the city including the grand Italianate city hall.
