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.
Irish people
In the Republic of Ireland, as of 2011, 3,861,335 people or about 84.16% of the population are Roman Catholic. In Northern Ireland about 41.6% of the population are Protestant (19.1% Presbyterian, 13.7% Church of Ireland, 3.0% Methodist, 5.8% Other Christian) whilst approximately 40.8% are Catholic as of 2011.
The 31st International Eucharistic Congress was held in Dublin in 1932, that year being the supposed 1,500th anniversary of Saint Patrick's arrival. Ireland was then home to 3,171,697 Catholics, about a third of whom attended the Congress. It was noted in "Time Magazine" that the Congress' special theme would be "the Faith of the Irish". The massive crowds were repeated at Pope John Paul II's Mass in Phoenix Park in 1979. The idea of faith has affected the question of Irish identity even in relatively recent times, apparently more so for Catholics and Irish-Americans. Today the majority of Irish people in the Republic of Ireland identify as Catholic, although church attendance have significantly dropped in recent decades. In Northern Ireland, where almost 50% of the population is Protestant, there has also been a decline in attendances.
