Demographics Portsmouth is the only city in the United Kingdom whose population density exceeds that of London. In the 2021 census, the city had 208,100 residents. The city used to be even more densely populated, with the 1951 census showing a population of 233,545. In a reversal of that decrease, its population has been gradually increasing since the 1990s. With about 860,000 residents, South Hampshire is the fifth-largest urban area in England and the largest in South-East England outside London; it is the centre of one of the United Kingdom's most-populous metropolitan areas. The city is predominantly white (91.8% of the population). However, Portsmouth's long association with the Royal Navy ensures some diversity. Some large, well-established non-white communities have their roots in the Royal Navy, particularly the Chinese community from British Hong Kong. Portsmouth's long industrial history with the Royal Navy has drawn many people from across the British Isles (particularly Irish Catholics) to its factories and docks. According to the 2011 census, Portsmouth's population was 84% White British, 3.8% other White, 1.3& Chinese, 1.4% Indian, 0.5% mixed race, 1.8% Bangladeshi, 0.5% other, 1.4% Black African, 0.5% white Irish, 1.3% other Asian, 0.3% Pakistani, 0.3% Black Caribbean and 0.1% other Black. Ethnicity Government and politics The city is administered by Portsmouth City Council, a unitary authority which is responsible for local affairs. Portsmouth was granted its first market town charter in 1194. In 1904, its boundaries were extended to all of Portsea Island and were later expanded onto the mainland of Great Britain between 1920 and 1932 by incorporating Paulsgrove, Wymering, Cosham, Drayton and Farlington into Portsmouth. Portsmouth was granted city status on 21 April 1926. On 1 April 1974, it formed the second tier of local government (below Hampshire County Council); Portsmouth and Southampton became administratively independent of Hampshire with the creation of the unitary authority on 1 April 1997. The city is divided into two parliamentary constituencies, Portsmouth South and Portsmouth North, represented in the House of Commons by Stephen Morgan of the Labour Party and Penny Mordaunt of the Conservative Party
