Dublin's Divorce Rate Is Among the Lowest in Europe. Nobody's Framing That as a Housing Crisis.

Let's start with the number Ireland gets to feel smug about.

Ireland's crude divorce rate sits at roughly 0.6 to 0.9 per 1,000 people — among the lowest in the European Union, well under half the EU-27 average of about 1.6, according to Central Statistics Office and Eurostat data. Divorce was only legalized in Ireland in 1996, and three decades later, the country still has one of the most stable-looking marriage records in Europe by that single measure.

The easy version of the story stops there — Irish marriages simply work better. But CSO's own data quietly undercuts that reading the moment you look past the divorce figure to the marriage figure sitting next to it. Dublin has one of the highest proportions of single adults of any county in Ireland, at 53.2%, according to CSO census data — trailing only Galway. Fewer than 37% of Dublin's adult population is married, the lowest share anywhere in the country. Whatever is keeping Ireland's divorce rate low, it isn't primarily that Dubliners are exceptionally good at staying married. It's that an unusually large share of them aren't getting married — or partnered, or cohabiting — in the first place.

The reason isn't cultural. It's structural, and it has a name everyone in Dublin already uses: the housing crisis.

CSO data found that 70% of 25-year-olds in Ireland are living at home with their parents. A 2025 survey by Catholic marriage-guidance agency Accord found that 69% of 25-to-34-year-olds say the cost of owning a home is directly delaying their marriage and family plans — and participation in Accord's marriage preparation courses, which most Catholic couples in Ireland take before their wedding, fell from 7,281 couples in 2023 to just 5,194 in 2024, a drop of nearly 30% in a single year. That's not a shift in taste. It's a shift in who can afford to reach the milestone at all.

The effect on actual dating, not just marriage, shows up in research most people wouldn't think to check. Dating app Bumble found that 70% of Irish daters say it's harder to date while living with parents or housemates, and 43% reported their relationships getting artificially accelerated by the living situation itself — moving in together, or getting serious faster than they otherwise would, simply to escape a childhood bedroom or a house share, rather than because the timing was actually right. Nearly a quarter of those living with parents in this research were between 24 and 35 — an age range where, a generation ago, most people would have had years of independent living behind them before they ever got serious with someone.

This is where Dublin's version of the story diverges from Ireland's national one. The National Economic and Social Council has specifically flagged that population growth in Ireland's five cities, Dublin included, is happening around the cities rather than in them — high housing costs and short-term lets pushing people, and particularly young adults trying to build independent lives, out to the commuter belt or back into a parent's house. For daters, that means the population most likely to be looking for a partner is also the population least likely to have a stable, independent home to build a relationship inside of — and increasingly likely to be priced out of the city center entirely, adding commute and logistics to every stage of dating that used to be simple.

Put the numbers together and Dublin's low divorce rate stops looking like a national success story and starts looking like a supply problem wearing a stability costume. Divorce requires a marriage to dissolve. A city where accessing independent adult life is this delayed, this expensive, and this dependent on a rental or mortgage market NESC itself describes as historically strained, is a city that's going to produce fewer marriages almost by default — regardless of how many people there actually want one.

None of this means Dubliners don't want to partner up, move in, and build a life with someone. The Accord and Bumble data both suggest exactly the opposite — that people are trying to do it faster and under more pressure than they should have to, precisely because the alternative is staying in a childhood bedroom into their thirties. The low divorce rate was never proof that Dublin has this figured out. It's a proxy for how few people are getting far enough to test it.
