South Derbyshire

Constituency profile

South Derbyshire is a constituency in Derbyshire in the East Midlands of England, covering most of the local government district of the same name. Its largest town is Swadlincote, which has a population of around 37,000. Other settlements include the town of Melbourne and the villages of Overseal, Woodville, Repton, Stenson Fields and Etwall.

This is a mostly rural constituency covering the towns and villages south of Derby. Swadlincote is a formerly industrial town with a history of coal mining. There is some deprivation in the town, however the rest of the constituency is affluent. Melbourne is a historic, small market town and Repton is known for Repton School, an elite public boarding school. House prices across the constituency are generally similar to the rest of the East Midlands and lower than the UK average.

Residents of South Derbyshire have a similar age profile to the rest of the country, although with a below-average proportion of young adults. Residents have average rates of income, high levels of homeownership, and the child poverty rate is low. They have average levels of education and a high proportion work in the manufacturing and accommodation sectors. The percentage of residents claiming unemployment benefits is low. White people made up 93% of the population at the 2021 census. Asians, mostly of Indian origin, were 4% of residents but made up around a fifth of the population in Stenson Fields, a suburb of Derby.

At the local district council, Swadlincote is represented by the Labour Party whilst the rural villages elected Conservatives. At the county council, which held elections more recently (in 2025), most of the constituency's seats were won by Reform UK. Voters in South Derbyshire strongly supported leaving the European Union in the 2016 referendum; an estimated 61% voted in favour of Brexit compared to the UK-wide figure of 52%.
