The City of Sheffield is a metropolitan borough with city status in South Yorkshire, England. The metropolitan borough includes the administrative centre of Sheffield, the town of Stocksbridge and the larger village of Chapeltown and part of the Peak District. It has a population of 582,493 (2024), making it technically the fourth largest city in England by population behind Birmingham, Leeds and Manchester, since London is not considered a single entity. It is governed by Sheffield City Council.
The current city boundaries were set on 1 April 1974 by the provisions of the Local Government Act 1972, as part of a reform of local government in England. The city is a merger of two former local government districts; the unitary City and County Borough of Sheffield combined with the urban district of Stocksbridge and parts of the rural district of Wortley from the West Riding of Yorkshire.
