Before the partition of Ireland, it was one of the counties of the Kingdom of Ireland from 1613 onward and then of the United Kingdom after the Acts of Union 1800. Adjoining the north-west shore of Lough Neagh, the county covers an area of 2,118 km (818 sq mi) and today has a population of about 252,231.
Since 1972, the counties in Northern Ireland, including Londonderry, have no longer been used by the state as part of the local administration. Following further reforms in 2015, the area is now governed under three different districts: Derry and Strabane, Causeway Coast and Glens and Mid-Ulster. Despite no longer being used for local government and administrative purposes, it is sometimes used in a cultural context in All-Ireland sporting and cultural events (i.e. Derry GAA).
Since 1981, it has become one of four counties in Northern Ireland that has a Catholic majority (55.56% according to the 2001 Census and 61.3% according to the 2021 Census). The county flower is the purple saxifrage.
