This became known as the shire town or later the county town. In many cases, the shires were named after their shire town (for example Bedfordshire), but there are several exceptions, such as Cumberland, Norfolk and Suffolk. In several other cases, such as Buckinghamshire, the modern county town is different from the town after which the shire is named. (See Toponymical list of counties of the United Kingdom) Most non-metropolitan counties in England are run by county councils and are divided into non-metropolitan districts, each with its own council. Local authorities in the UK are usually responsible for education, emergency services, planning, transport, social services, and a number of other functions. Until 1974, the county boundaries of England changed little over time. In the medieval period, a number of important cities were granted the status of counties in their own right, such as London, Bristol and Coventry, and numerous small exclaves such as Islandshire were created. In 1844, most of these exclaves were transferred to their surrounding counties. Northern Ireland In Northern Ireland, the six county councils, if not their counties, were abolished in 1973 and replaced by 26 local government districts. The traditional six counties remain in common everyday use for many cultural and other purposes. Scotland and Wales The thirteen historic counties of Wales were fixed by statute in 1539 (although counties such as Pembrokeshire date from 1138) and most of the shires of Scotland are of at least this age. The Welsh word for county is sir which is derived from the English 'shire'. The word is officially used to signify counties in Wales. In the Gaelic form, Scottish traditional county names are generally distinguished by the designation —literally "sheriffdom", e.g. (Argyllshire). This term corresponds to the jurisdiction of the sheriff in the Scottish legal system. North America Canada In Ontario, Quebec and Nova Scotia, provinces that have a two-tier system of local government, the counties constitute the upper tier and local municipalities form the lower tier. Manitoba and Saskatchewan are divided into rural municipalities. The Northwest Territories and Nunavut are divided into regions; however, these regions only serve to streamline the delivery of territorial governmental services, and have no government of their own. Newfoundland and Labrador, and Yukon do not have any second-level administrative subdivision between the provincial/territorial government and their municipalities.
