Local authority district

The districts of England are a level of subnational division of England used for the purposes of local government. They are officially categorised by the Office for National Statistics as "local authority districts" (LADs). Although the City of London Corporation and the Council of the Isles of Scilly are sui generis local authorities, the Office for National Statistics officially categorises both the City of London and the Isles of Scilly as LADs for statistical purposes. With the exception of those two authorities, every district in England is classified as either a London borough, a metropolitan district, or a non-metropolitan district.
