South Derbyshire constituency covers Derbyshire to the south of the city of Derby, forming a tapering salient surrounded by Staffordshire and Leicestershire. The constituency was originally created after the Reform Act in 1832 when Derbyshire was divided into North Derbyshire and South Derbyshire. The present constituency was created in 1983 from parts of the seats of Derby North, Derby South, Belper, and South East Derbyshire. When Parliament implemented the plans of the Boundary Commission's Fourth Periodic Review of Westminster constituencies 1995 that came into effect for 1997, Mickleover ward was transferred to Derby South. Under the Fifth Periodic Review of Westminster constituencies, approved for the 2010 general election, the constituency shed the two City of Derby wards to become coterminous with its district.
Constituency profile
This constituency consists of rural and semi-rural settlements, including Repton, in which a majority of voters have, in local elections since World War II, been Tory-voting, plus more historically industrial, and manufacturing-focussed settlements such as Swadlincote where the electorate has been for the most part Labour-voting. Workless claimants were in November 2012 significantly lower than the national average of 3.8%, at 2.2% of the population based on a statistical compilation by The Guardian, and very close to that of the Mid Derbyshire seat, at 1.9%. Also similar is the regionally lowest jobseeker seat of Derbyshire Dales, with only 1.5% of the population registered as jobseekers.
