Derg (District Electoral Area)

Derg is one of the seven district electoral areas (DEA) in Derry and Strabane, Northern Ireland. The district elects five members to Derry and Strabane District Council and contains the wards of Castlederg, Finn, Glenderg, Newtownstewart and Sion Mills. Derg forms part of the West Tyrone constituencies for the Northern Ireland Assembly and UK Parliament.

It was created for the 1985 local elections, replacing Strabane Area A which had existed since 1973, where it originally contained five wards (Castlederg, Clare, Finn, Glenderg and Newtownstewart). For the 2014 local elections it remained at five wards but gained Sion Mills from the abolished Mourne DEA.
