Christianity is the predominant religion, and while Ireland remains a predominantly Catholic country, the percentage of the population who identified as Catholic on the census has fallen sharply from 84.2 percent in the 2011 census to 78.3 percent in the most recent 2016 census. Other results from the 2016 census are : 4.2%  Protestant, 1.3% as Muslim, and 9.8% as having no religion.

In 2011, it was reported that weekly Mass attendance in Dublin was just 18%, with it being even lower among younger generations.
