Ireland’s Central Statistics Office reported that between 1991 and 2011, the percentage of Irish residents who were Muslim jumped from 0.1 percent to 1 percent (equating to about 49,000 people). By 2020, Ireland’s Islamic population will more than double to at least 100,000. The increase is attributed to both immigration and population growth. The second fastest-growing faith in Ireland is Orthodox Christianity, largely due to immigration from Eastern Europe — doubling in just five years between 2006 and 2011 to more than 45,000 people.
The Census figures also indicated that 84 percent of the Irish population identify as Catholic, down from 91.6 percent in 1991. Moreover, only about one-third (34 percent) of Catholics in the country regularly attend Mass. Protestants now account for just 5 percent of the population. Part of the reduction in Christians in Ireland may be attributed to a dramatic increase in the number of people who claim to believe in no organized religion — having surged by 400 percent between 1991 and 2011 to almost 280,000 people.
As their numbers climb, Muslims in Ireland have embarked on projects to build more mosques, including a new $50 million complex in north Dublin that will commence construction in 2014 and become the country’s largest mosque. Illume Magazine reported that the new mosque, at the Clongriffin Centre, will be large enough to hold more than 3,000 people and feature two minarets, a prayer hall, a cultural center, offices, bookshop, a library, a mortuary, a 600-seat events center, school and even a fitness center and apartments. Muslims in Ireland are also free to wear the veil and hijab, unlike in France.
