Catholic Church in Ireland
In the 2016 Irish census 78.3% of the population identified as Catholic in Ireland; numbering approximately 3.7 million people. Unlike Catholics in the United States, Ireland has seen a significant decline from the 84.2% who identified as Catholic in the 2011 census.
Sectarian violence
For people who describe themselves as Protestant or Roman Catholic, a small majority of them appear to favour one of the two main political parties on either side: the Democratic Unionist Party or the Ulster Unionist Party for Protestants; and Sinn Féin or the Social Democratic and Labour Party for Roman Catholics. In each case, the percentage in the "Northern Irish Life & Times Survey" in 2015 was 57%. Roman Catholics are more likely to reject the label British (59%) than Protestants are to reject the label Irish (48%).
