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.
Repartition of Ireland
Pollsters have rarely asked the population of Northern Ireland about their attitudes to repartition but it was asked twice in the early 1980s. In June 1981 and February 1982, the percentages of Protestants agreeing to repartition was 9% and 8%; the percentages for Catholics were 22% and 24%.
