The past decade has witnessed a significant decline in Catholic baptisms across Ireland, with a nearly 30% drop attributed to various factors. The Iona Institute’s recent analysis attributes this trend to lower birth rates and increasing secularization.
Data gathered from nearly all Catholic dioceses in Ireland reveal a 29.6% decrease in baptisms over the last ten years. Declining birth rates account for approximately 60% of this reduction, while the remainder is linked to a shift towards secular beliefs.
Birth rates across Ireland have diminished by 18.8%, with the Republic of Ireland experiencing a 17.9% drop and Northern Ireland seeing a 21.3% decrease.
Notably, the decline in baptisms varies across regions. Dublin experienced one of the most significant reductions, with baptisms plummeting by 39.9%, from 15,759 in 2015 to 9,465 in 2025. Meath recorded a slightly higher decrease of 40.8%, while Down and Connor, including Belfast, saw a 37.9% drop.
In contrast, Achonry experienced a modest decline of 3.2%, and Elphin reported a slight increase of 0.9%. Kerry’s decline was 22.3%.
The Iona Institute emphasizes that these figures cannot solely be attributed to secularization, noting that the reduced number of births plays a more significant role.
Census data highlights a noticeable change in the religious identity of young children in the Republic. In 2016, 78.3% of children aged zero to four were identified as Roman Catholic, decreasing to 65.4% by 2022. Correspondingly, the percentage of children with no religious affiliation rose from 9.2% to 15.6% during the same period.
Despite these shifts, the institute indicates that the majority of Catholic-identifying parents still choose baptism for their children. In the 2022 Census, 67.9% of mothers aged 25 to 39 with children under five identified as Roman Catholic, aligning closely with the 65.4% of children in that age group recorded as Catholic.
This trend suggests that “cultural Catholicism” remains prevalent in Ireland, even as regular church attendance and participation in other sacraments decline.
Some Catholic couples may marry outside the church but still opt for baptism, First Holy Communion, and Confirmation for their children.
Dr. Tom Finegan, chairman of The Iona Institute, remarked that the decline was expected, considering the falling birth rates and rising secularization. He stated, “Given that births have fallen by almost a fifth in the last ten years, and more people are ticking the ‘No Religion’ box in the Census, we could expect nothing but a big drop in baptism figures.”
Regional differences underscore the influence of demographics and secularization. Dublin witnessed a 21.9% decline in births from 2015 to 2025, surpassing the Republic’s overall 17.9% drop. Additionally, Dublin has a higher proportion of young children with no religious affiliation, with 21.9% recorded as such in the 2022 Census, compared to 15.6% nationally.
A similar trend is observed in Belfast, where 25.5% of children under five were recorded as having no religion in 2021, up from 17.5% in 2011. Among women aged 25 to 44, the proportion with no religion increased from 14.4% to 25.2% during the same period.
Dr. Finegan highlighted that the decline in baptisms is largely due to falling birth rates rather than solely secularization. He also pointed to Ireland’s fertility rate of approximately 1.5 children per woman, falling short of the 2.1 needed for population replacement, emphasizing, “This should be of concern to everyone, regardless of religious belief.”
The briefing concludes that Ireland’s baptism decline reflects two simultaneous trends: fewer births and a growing number of families identifying as non-religious. “As almost all parents who consider themselves to be Catholic still have their children baptised shows that ‘cultural Catholicism’ still remains quite strong in Ireland,” it stated. “It remains to be seen what happens to baptism numbers if and when ‘cultural Catholicism’ fades as a force in Irish life.”
