The constituency consisted of inner city areas of Belfast equivalent to the modern areas of Unity, Brown Square, John Street and Lancaster Street. Residential redevelopment caused the electorate to fall sharply from 20,399 in 1929 to 6,384 in 1969. By the time of the dissolution of the Stormont Parliament, it had just over 2,500 voters.
The constituency was one of the most staunchly nationalist in Belfast. It was initially held by Nationalist Party members, then later by a variety of labour movement activists and members of smaller nationalist parties.[1] In 1953, a split between three Labour candidates led to the Unionist candidate finishing just 576 votes behind the victor.
