North Down Borough Council is a Local Council in County Down in Northern Ireland. It is set to merge with Ards Borough Council in May 2015 under local government reorganisation in Northern Ireland to become North Down and Ards District Council.
Its main town is Bangor, 20 km east of Belfast with a population of approximately 55,000. The Council is headquartered in Bangor. Its secondary centre is the former Urban District of Holywood, 8 km northeast of Belfast with a population of approximately 10,000. Most of the remainder of a total population is in suburban villages along the southern shore of Belfast Lough. The Borough is heavily suburbanised, railway links with Belfast are good and the area has been the domain of Belfast commuters since the mid-19th century. The Borough is often held to be the wealthiest area in Northern Ireland, although there are pockets of deprivation in a string of overspill public housing estates along the Bangor Ring Road.
The borough consists of 4 electoral areas: Abbey, Ballyholme and Groomsport, Bangor West and Holywood. In the 2011 election 25 members were elected from the following political parties: 11 Democratic Unionist Party, 6 Alliance, 4 Ulster Unionists, 1 Green, and 2 Independents. North Down along with Carrickfergus Borough Council are the only councils in Northern Ireland without Nationalist political party representation.
The Borough of North Down was formed in 1973 in the local government reorganisation from the old Bangor Urban District, Holywood Urban District, North Down Rural District and part of Castlereagh Rural District.
