Editing Yorkshire (section)

==Definitions==
There are several ways of defining Yorkshire, including the historic county and the group of four modern ceremonial counties. The county boundaries were reasonably stable between 1182, when it ceded western areas to the new county of Lancashire,<ref>{{cite web|url=http://www.highsheriffs.com/Lancashire/LancashireHistory.htm|title=High Sheriff – Lancashire County History |website=highsheriffs.com|access-date=17 April 2018|archive-url=https://web.archive.org/web/20160304185947/http://www.highsheriffs.com/Lancashire/LancashireHistory.htm|archive-date=4 March 2016|url-status=dead}}</ref> and 1889 when administrative counties were created, which saw some adjustments to the boundaries with County Durham, Lancashire and Lincolnshire.<ref>[[Local Government Act 1888]]</ref><ref name="Gibbons 1969"/> After 1889 there were occasional adjustments to accommodate urban areas which were developing across county boundaries, such as in 1934 when [[Dore, South Yorkshire|Dore]] and [[Totley]] were transferred from Derbyshire to Yorkshire on being absorbed into the borough of Sheffield.<ref>{{cite web |title=Sheffield Ancient Parish / Civil Parish |url=https://visionofbritain.org.uk/unit/10467767#tab02 |website=A Vision of Britain through Time |publisher=GB Historical GIS / University of Portsmouth |access-date=8 March 2024}}</ref>

More significant changes in 1974 saw the historic county divided between several counties. The majority of the area was split between North Yorkshire, South Yorkshire and West Yorkshire, which all kept the Yorkshire name. A large part of the east of the county went to the new county of [[Humberside]], and an area in the north-east went to the new county of [[Cleveland (county)|Cleveland]]. Some more rural areas at the edges of the historic county were transferred to County Durham, [[Cumbria]], Lancashire and [[Greater Manchester]], whilst South Yorkshire also included areas which had been in Nottinghamshire.<ref name=1972act>{{cite legislation UK|type=act|act=Local Government Act 1972|year=1972|chapter=70|access-date=8 March 2024|mode=cs1}}</ref>

Cleveland and Humberside were both abolished in 1996, since when there have been four [[Ceremonial counties of England|ceremonial counties]] with Yorkshire in their names: East Riding of Yorkshire, North Yorkshire, South Yorkshire and West Yorkshire, which together cover most of the historic county.<ref name=1995miscellaneous>{{cite legislation UK|type=si|si=The Local Government Changes for England (Miscellaneous Provision) Regulations 1995|year=1995|number=1748|access-date=6 March 2024|mode=cs1}}</ref>

There is a [[Regions of England|region]] called [[Yorkshire and the Humber]] which covers a similar area to the combined area of the four Yorkshire ceremonial counties, the exceptions being that the region excludes the parts of North Yorkshire which had been in Cleveland, but includes [[North East Lincolnshire]] and [[North Lincolnshire]] (which had been in Humberside). Until 2009 some government powers in the region were devolved to the [[Yorkshire and Humber Assembly]]; since 2009 the region has been used primarily for presentation of statistics.
