The City of Lancaster is a local government district of Lancashire, England, with the status of a city and non-metropolitan district. It is named after its largest settlement, Lancaster, but covers a far larger area, which includes the towns of Morecambe, Heysham, and Carnforth, as well as outlying villages, farms, rural hinterland and a section of the Yorkshire Dales National Park. The district has a population of 146,038, and an area of 222.5 square miles.
The current city boundaries were set as part of the provisions of the Local Government Act 1972, and cover an amalgamation of five former local government districts—the municipal boroughs of Lancaster and Morecambe and Heysham, together with the Carnforth Urban District and rural districts of Lancaster and Lunesdale, all from the administrative county of Lancashire.
