West Yorkshire consists of five metropolitan boroughs (City of Bradford, Calderdale, Kirklees, City of Leeds and City of Wakefield) and is bordered by the counties of Derbyshire to the south, Greater Manchester to the south-west, Lancashire to the north-west, North Yorkshire to the north and east, and South Yorkshire to the south and south-east.
Remnants of a strong industrialisation in coal, wool and iron ore industries remain in the county having attracted people over the centuries, and this can be seen in the buildings and architecture. The greatest hub Leeds may become a terminus for a north-east limb of High Speed 2. Major railways and three major motorways traverse the county. In the heart of the county is Leeds Bradford International Airport.
West Yorkshire County Council was abolished in 1986 so its five districts became effectively unitary authorities. However, the metropolitan county, which covers an area of 2,029 square kilometres (783 sq mi), continues to exist in law, and as a geographic frame of reference. Since 1 April 2014 West Yorkshire has been a combined authority area, with the local authorities pooling together some functions over transport and regeneration as the West Yorkshire Combined Authority.
West Yorkshire was formed as a metropolitan county in 1974, by the Local Government Act 1972, and corresponds roughly to the core of the historic West Riding of Yorkshire and the county boroughs of Bradford, Dewsbury, Halifax, Huddersfield, Leeds, and Wakefield.
