South Yorkshire is a ceremonial and metropolitan county governed as a combined authority in north-central England. It had a population of 1.34 million in 2011 and has an area of 1,552 square kilometres (599 sq mi). The county consists of four metropolitan boroughs—the cities of Sheffield and Doncaster, and the boroughs of Barnsley and Rotherham—collectively administered by a directly-elected mayor. Lying on the east side of the Pennines, South Yorkshire is landlocked, and borders Derbyshire to the west and south-west, West Yorkshire to the north-west, North Yorkshire to the north, the East Riding of Yorkshire to the north-east, Lincolnshire to the east and Nottinghamshire to the south-east. The largest settlement is Sheffield, its built-up area is the tenth most populous in the United Kingdom. With over half of the county's population living within the built-up area, it dominates the county's western half. South Yorkshire was created on 1 April 1974 as a result of the Local Government Act 1972. It was created from 32 local government districts of the West Riding of Yorkshire (the administrative county and four independent county boroughs), with small areas from Derbyshire and Nottinghamshire. South Yorkshire County Council was abolished in 1986 and its metropolitan boroughs effectively becoming unitary authorities, although the metropolitan county continues to exist in law. As a ceremonial county, South Yorkshire has a Lord Lieutenant and a High Sheriff. The area lies within the Sheffield City Region local enterprise partnership with Barnsley also being within the Leeds City Region, reflecting its geographical position midway between the cities. In 2022, Doncaster became one of eight towns to successfully bid for city status; this was awarded on 1 November 2022 and made Doncaster South Yorkshire's second city after Sheffield. The remaining two boroughs are Barnsley and Rotherham.
