Note that the initial question on religion in our census assumes that the respondent has a religion, and that religions are presented in declining order of popularity in the previous census, but No Religion, the second most popular response by a wide margin, is listed in seventh place, separate from the rest of the list.
The study Religious Practice and Values in Ireland, done by the Irish Catholic Bishops Conference  in 2010 found that 82 per cent of the republic's population label themselves as Roman Catholic, but of those,

* Half don’t believe in hell
* 30 per cent don’t believe in life after death
* Quarter don’t believe in heaven and
* 10 per cent don’t believe in god.

Which makes you wonder exactly what exactly the five per cent of Irish people who identify as Catholics, do not believe in life after death but do believe in heaven are thinking.
