Constituency profile

Portsmouth North is a constituency in Hampshire in South East England. It covers the northern half of Portsea Island and the mainland areas of the city of Portsmouth. This includes the neighbourhoods of Baffins, Copnor, Stamshaw, Hilsea, Paulsgrove, Wymering, Cosham, Drayton and Farlington.
Portsmouth is a port city with a maritime history. Its importance as a naval base and centre for shipbuilding made it the most heavily fortified city in the world in the early 19th century.[2] Within this constituency, the neighbourhoods on Portsea Island (Baffins, Copnor, Stamshaw and Hilsea) mostly feature dense Edwardian and interwar terraced housing, whilst the mainland suburbs were developed more recently as the city expanded. The neighbourhoods in the west like Stamshaw and Paulsgrove, the latter of which was built as a large council estate, are highly-deprived. The north-eastern suburbs of Drayton and Farlington are affluent in comparison, giving the constituency an average level of wealth overall.[3] House prices across the constituency are generally lower than the UK average and considerably lower than the regional average.[4]
Portsmouth North has a similar age profile to the rest of the country, although there are more middle-aged adults and a lower proportion of retirees.[5] Residents' rates of income, homeownership and child poverty are in line with UK averages.[4][6] They have below-average levels of education and a high proportion work in the health and manufacturing sectors.[4][7] The percentage claiming unemployment benefits is similar to the country as a whole.[6] White people made up 90% of residents at the 2021 census.[8]
At the local city council, the neighbourhoods closer to the city centre are represented by Liberal Democrats, the wealthy north-eastern suburbs by Conservatives and the rest of the constituency by localists and Reform UK. Voters in Portsmouth North strongly supported leaving the European Union in the 2016 referendum; an estimated 64% voted in favour of Brexit compared to the UK-wide figure of 52%.[4]
