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.[18]
passage: History of Ireland
With the partition of Ireland in 1922, 92.6% of the Free State's population were Catholic while 7.4% were Protestant.[39] By the 1960s the Protestant population had fallen by half. Although emigration was high among all the population, due to a lack of economic opportunity, the rate of Protestant emigration was disproportionate in this period. Many Protestants left the country in the early 1920s, either because they felt unwelcome in a predominantly Catholic and nationalist state, because they were afraid due to the burning of Protestant homes (particularly of the old landed class) by republicans during the civil war, because they regarded themselves as British and did not wish to live in an independent Irish state, or because of the economic disruption caused by the recent violence. The Catholic Church had also issued a decree, known as Ne Temere, whereby the children of marriages between Catholics and Protestants had to be brought up as Catholics. From 1945, the emigration rate of Protestants fell and they became less likely to emigrate than Catholics.
