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.
Protestantism in Ireland
The previous pattern of decline started to change during the 1990s. By the time of the 2006 census of the Republic of Ireland, a little over 5% of the state was Protestant. The 2011 census of the Republic of Ireland found that the Protestant population in every county had grown. In 2012, the "Irish Independent" reported that "Irish Anglicanism is undergoing a quite remarkable period of growth" due to immigration and Irish Catholics converting.
