The Greater Derry area, the area within about 20 mi (32.2 km) of the city, has a population of 237,000[2] and comprises Derry City Council, Limavady Borough Council, Strabane District council excluding the Castlederg area, and parts of North East Donegal in the Republic of Ireland, namely Inishowen, Letterkenny, Ballybofey/Stranorlar and Lifford.[3] The term, like the term Greater Belfast, has no official relevance particularly in this case, since it incorporates areas from two jurisdictions; however, it is used for ease of reference.
