It was a single-member division of County Antrim represented in the Parliament of Northern Ireland. Before 1929, it was part of the seven-member Antrim constituency. The constituency sent one MP to the House of Commons of Northern Ireland from 1929 until the Parliament was temporarily suspended in 1972, and then formally abolished in 1973. In terms of the then local government areas the constituency in 1929 comprised parts of the rural districts of Ballymena, Ballymoney and Larne.
