Ireland’s marriage rate has now reached its lowest ever level, not including the years of the pandemic, according to new data from the Central Statistics Office. At 3.8 marriages per thousand adults last year, the rate has fallen below the EU average and is very likely to fall even lower.
In 2024, there were 19,680 opposite-sex marriages registered in Ireland, marking a 4.1pc decrease from 2023’s total of 20,513. The marriage rate for opposite-sex couples now stands at 3.7 per 1,000 adults. The current EU average is approximately 4.0 per 1,000.
What going on? For a start, the population is ageing, meaning the number of people of typically marriageable age is declining as a share of all adults. This alone will reduce the marriage rate.
But when we zero in on those who are of typically marriageable age (20-40 years old), what is happening?
Well, the marriage rate among those in their early to mid-20s has dropped hugely in the last ten years alone. For males aged 20–24, the rate dropped from 4.1 to just 1.8 per 1,000, and for females in the same age group, from 8.1 to 2.6 per 1,000.
You might consider this a good thing, if you think getting married in your early to mid-20s is too soon.
But we have also seen a big decline in marriage rates among those in their mid to late-20s. Among males aged 25–29 it has dropped from 29.7 per 1,000 to 13.9 since 2014, and among females in this age cohort from 39.8 to 21.8 per 1,000.
If marriage rates among those in their 20s are declining, then maybe there is a pickup by the time people reach their thirties? Yes, far more people marry in their 30s than in their 20s, but not by enough to increase marriage rates overall.
Among the 30–34 age cohort marriage rates have barely budged in the last ten years. Males experienced a slight decrease from 49.3 to 43.5 per 1,000, while females saw a marginal increase from 44.3 to 44.9 per 1,000.
For the 35–39 cohort, male marriage rates slightly decreased from 24.1 to 23.7 per 1,000, whereas female rates increased from 17.5 to 17.8 per 1,000.
Therefore, two things seem to be happening. First, people are waiting much longer to marry, but secondly, fewer people are marrying, full stop. We can expect this trend to continue. Fertility rates almost always follow marriage rates on a downward course and Ireland’s fertility rate is now just 1.5, well below the replacement level of 2.1.
These are awful trends if you care about the future of Irish society.
The new marriage data from the CSO confirm a trend that has emerged over the past few years: the rise of “New Age” weddings and the decline of traditional religious ceremonies.
Catholic ceremonies remained the most popular form of marriage, but only just, accounting for 32.6pc of opposite-sex marriages in 2024, though this represents a notable 11.5pc decline compared to 2023. The decline in Church of Ireland ceremonies was even more dramatic with a fall of 20.2pc last year. Conversely, “Other Religious” ceremonies increased significantly (+16.2pc) and now represent almost 20pc of all ceremonies.
To this must be added ceremonies conducted by the ‘Spiritualist Union of Ireland’ which accounted for 7.1pc of the total. This means that cohort of weddings accounted for around 26pc of all wedding ceremonies last year.
Among non-religious ceremonies, humanist weddings declined by 10.8pc year-on-year, while civil ceremonies also saw a slight decrease in numbers (-1.3pc).
Civil ceremonies include Christians who marry abroad, and also Muslim or Hindu couples, for example, who do not have a religious solemniser recognised by the State here.
Wedding ceremonies in Ireland have undergone substantial changes since 2007, the year when civil ceremonies were first permitted outside registry offices. Today, many hotels offer religious ceremonies performed by solemnisers belonging to new ‘religious organisations’, explaining the explosion of “other religious” ceremonies.
Alternative religious ceremonies are also growing in popularity among same-sex couples. In 2024, almost 40pc of same-sex marriages were religious ceremonies. Both Spiritualist and “Other Religious” ceremonies are now more popular than Humanist ceremonies, which dropped by 30pc in 2024 among same-sex couples.
This trend suggests that Ireland is not becoming more secular, but arguably more pagan.
