Demography
Derry Urban Area (DUA), including the city and the neighbouring settlements of Culmore, Newbuildings and Strathfoyle, is classified as a city by the Northern Ireland Statistics and Research Agency (NISRA) since its population exceeds 75,000. On census day (March 27th 2011) there were 105,066 people living in Derry Urban Area. Of these, 27% were aged under 16 years and 14% were aged 60 and over; 49% of the population were male and 51% were female; 75% were from a Roman Catholic background and 23% (up three percent from 2001) were from a Protestant background.
The mid-2006 population estimate for the wider Derry City Council area was 107,300. Population growth in 2005/06 was driven by natural change, with net out-migration of approximately 100 people.
The city was one of the few in Ireland to experience an increase in population during the Irish Potato Famine as migrants came to it from other, more heavily affected areas.
