Religion in the Republic of Ireland
Christianity is the largest religion in the Republic of Ireland based on baptisms. Irish Christianity is dominated by the Catholic Church, and Christianity as a whole accounts for 82.3% of the Irish population. Most churches are organized on an all-Ireland basis which includes both Northern Ireland and the Republic of Ireland.
Irish travellers have traditionally adopted a very particular attitude to the Catholic Church, with a focus on figures such as "healing priests". More generally a tradition of visions continues, often outside of Church sanction.
Northern Ireland

The biggest of the Protestant/non-Roman Catholic Christian denominations were the Presbyterian Church (19%), the Church of Ireland (14%) and the Methodist Church (3%). In terms of community background (i.e. religion or religion brought up in), 48% of the population came from a Protestant background, 45% from a Catholic background, 0.9% from non-Christian backgrounds, and 5.6% from non-religious backgrounds.
