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.
Christianity in Ireland
Like other Irish churches, the Church of Ireland did not divide when Ireland was partitioned in the 1920s, and it continues to be governed on an all-Ireland basis. Today the Church of Ireland is, after the Catholic Church, the second-largest Christian church in all of Ireland and the third largest in Northern Ireland after the Catholic and Presbyterian churches. It is governed by a synod of clergy and laity and organised into two ecclesiastical provinces: Armagh, led by the Archbishop of Armagh (styled "Primate of All Ireland"), currently Richard Clarke and Dublin, led by the Archbishop of Dublin, Michael Jackson.
