Ulster (Ulaidh or Cúige Uladh, is one of the provinces of Ireland, located in the north of the island.


Ulster has a population of just over 2 million people and an area of 21,552 square kilometres (8,321 sq mi). Its biggest city, Belfast, has an urban population of over half a million inhabitants, making it the second-largest city in Ireland and the 10th largest urban area in the UK.

Six of Ulster's nine counties, Antrim, Armagh, Down, Fermanagh, Londonderry and Tyrone, form Northern Ireland which remained part of the United Kingdom after the partition of Ireland in 1921. Three Ulster counties – Cavan, Donegal and Monaghan – form part of the Republic of Ireland. About half of Ulster's population lives in counties Antrim and Down.


Across the nine counties, according to the aggregate UK 2011 Census for Northern Ireland, and Irish 2011 Census for counties Cavan, Donegal and Monaghan, there is a slim Catholic majority over Protestant (50.8% against 42.7%).
