Religion in the Republic of Ireland
The predominant religion in the Republic of Ireland is Christianity, with the largest church being the Roman Catholic Church. The Irish constitution says that the state may not endorse any particular religion and guarantees freedom of religion.

Nugent criticised the question “What is your religion?” in the 2011 Irish census. He said the census should instead ask “Do you have a religion?” and “If so, what is it?” He asked nonreligious Irish people to tick the No Religion box. He warned that joke responses to the religion question in the census, being categorised as “not stated”, potentially contribute to an underreporting of the number of non-religious people.
