A civil parish is a country subdivision, forming the lowest unit of local government in England. There are 218 civil parishes in the ceremonial county of Cornwall, which includes the Isles of Scilly. The county is effectively parished in its entirety; only the unpopulated Wolf Rock is unparished. At the 2001 census, there were 501,267 people living in the current parishes, accounting for the whole of the county's population. The final unparished areas of mainland Cornwall, around St Austell, were parished on 1 April 2009 to coincide with the structural changes to local government in England.
