People getting married are older, with Friday the most popular day to tie the knot, and August and September the busiest months for weddings.
Latest figures from the Central Statistics Office show that while the number of marriages increased in 2021, it was still 15% below pre-pandemic levels.
The average age of brides in 2021 was 35.4 years, compared to 34.8 years in 2019, while grooms were also slightly older - 37.4 years last year compared to 36.8 years in 2019.
The average age for couples in same sex marriages was 40.1.
The figures also show that 40% of opposite-sex couples - 6,721 - had a Catholic marriage ceremony, while 34% - 5,659 - opted for a civil ceremony.
However, the popularity of both these ceremonies has been in decline since 2014, when they accounted for 87% of all marriage ceremonies.
For same-sex couples, a civil ceremony was the choice for 66% (328) of couples, while a Humanist ceremony 13.6% (68) of all same-sex marriages in 2021, and 8.3%, or 1,394, of all opposite sex marriages.
With weddings back on the calendar following the easing of Covid-19 restrictions, August and September proved to be the most popular months for opposite-sex couples to marry, with September and July the months of choice for same-sex couples.
January was the least favoured month to tie the knot for all couples.
Thursday, Friday and Saturday are the most popular days to marry, with Sunday and Tuesday the least popular.
