Cork South-Central is predominantly an urban constituency but with a rural hinterland in the south. It encompasses the electoral areas of Cork City Council south of the river Lee, together with most of the Carrigaline electoral area of Cork County Council, including the Ringaskiddy and Passage West areas. The Ballincollig area of County Cork was moved to the Cork North-West constituency for the 2007 general election. At the 2016 general election, the Bishopstown area of Cork city was moved to the Cork North-Central constituency, and it was also reduced from five to four seats.
