The ward has a population of 8,800 and is represented by Labour Party trio Mike Lewis, Ceinwen Thomas, and Gloria Tanner.
It lies approximately five kms north of Swansea city centre with its neighbouring wards of Morriston, Landore, Cwmbwrla, Penderry and Llangyfelach.
Mynyddbach has the eighth largest ward population and the eighth highest population density in Swansea.
It is a ward with a diverse housing stock which can be traced back, in its southern half, to coal mining and the early Victorian era.
The early 1900s saw the continuing northern expansion of housing in the ward and the construction of the large council estate at Clase in the 1950s.
Since then there has been a steady pattern of expansion and infill in this traditionally lower priced working class area of the city. Opening of the DVLA in the early 1970s at the northern end of the ward resulted in an upsurge in demand and prices within its vicinity.
The key localities in the ward are Treboeth, Mynydd Garnllwyd and Clase, which together offer a wide range of property types.
