Long-distance relationship statistics: which ones are real

Looking for long-distance relationship statistics for the UK? Here’s the awkward truth: nobody in the UK counts long-distance couples. The nearest official number comes from the 2021 Census, which found that 3.0% of people aged 16 and over in a legal partnership in England and Wales weren’t living in a couple, the same as in 2011 (ONS, 2023). That covers married and civil-partnered people living apart for any reason. It says nothing about dating couples in different cities.

Most of the confident percentages on stats pages come from somewhere much flimsier. This guide goes through the numbers you’ll actually run into: which come from real research, which don’t, and how to check the next one yourself.

What UK long-distance relationship statistics actually exist?

Two sources get close. Neither measures quite the thing people are searching for.

The census. It records who lives in each household, which is how the ONS arrives at that 3.0%. A married couple where one partner works away all week, and a couple who separated but never divorced, could both land in the same group. Useful for demographers. Not much use to someone in Dundee wondering whether their relationship with a partner in Cardiff is unusual.

Understanding Society. This large UK household survey started asking whether people had a partner living in another household in its third wave, carried out in 2011 and 2012. Researchers call that "living apart together", and it covers couples a few streets apart as well as couples at opposite ends of the country.

Using that data for Great Britain, Rory Coulter and Yang Hu found that 62% of people in these relationships intended to move in with their current partner within the next three years. They also found that, except among single parents, the odds of planning to move in rose the further apart the partners lived (Coulter and Hu, Journal of Family Issues).

That second finding is the most useful British number there is for couples apart. The further the distance, the more likely people were to be planning to close it.

So if you need a UK statistic, those are the honest ones. Anything promising "X% of British long-distance couples" deserves a hard look at where it came from.

The long-distance relationship statistics that hold up

These come from peer-reviewed journals or a named research organisation, and every one links to the original.

What it found	Who was studied	Source
34.2% of students in a relationship were long distance; happiness, commitment and conflict didn’t differ by distance	2,075 students in relationships, in a 2020 survey on one university campus	Beckmeyer, Herbenick and Eastman-Mueller, 2023
Long-distance partners disclosed more and idealised more, and both fed intimacy	Dating couples in a diary study	Jiang and Hancock, 2013
Few differences between long-distance and close relationships; personal and relationship traits predicted quality	717 people in long-distance and 425 in close relationships	Dargie, Blair, Goldfinger and Pukall, 2015
Long-distance partners rated their relationships higher on several measures of quality; break-up rates at follow-up matched close couples	A nationally representative sample of 870 people	Kelmer, Rhoades, Stanley and Markman, 2013
About half of long-distance dating couples moved to the same place and the other half broke up while apart; a third of reunited couples split within three months	Long-distance dating couples	Stafford, Merolla and Castle, 2006
No significant differences in satisfaction, intimacy, trust or relationship progress	194 people in long-distance and 190 in close premarital relationships	Guldner and Swensen, 1995
24% had used the internet or email to keep up a long-distance relationship, compared with 19% in 2005	Internet users with recent dating experience	Pew Research Center, 2013

Notice what’s missing. None of these is a survival rate for long-distance relationships in general, and none is a count of long-distance couples in Britain. Each describes a particular group, at a particular time, asked particular questions.

That’s what real research looks like. It’s narrower and less quotable than a headline, and far more use.

The popular statistics that don’t hold up

"58% of long-distance relationships succeed"

This one is everywhere. It comes from a 2018 poll of 1,000 American adults who had been in long-distance relationships, carried out by OnePoll and commissioned by KIIROO, a company that makes interactive sex toys (StudyFinds write-up). The same poll is behind the claim that four months in is when distance gets hardest.

Three problems. The write-up never says what counted as "success". A company that sells to couples apart paid for the poll, so it had every reason to like a hopeful number. And it asked American adults, so it tells you nothing about the UK anyway. Treat it as marketing.

"14 million couples", "40% break up" and "75% of engaged couples"

These American figures are credited to the Center for the Study of Long Distance Relationships and get copied from one stats page to the next. Even careful secondary sources label them estimates whose method isn’t fully published, rather than peer-reviewed findings (Lainie Research). If a number can’t be traced to a sample and a method, there’s nothing to check it against.

Here’s the twist. Gregory Guldner, whose name usually travels with those figures, did publish peer-reviewed research on long distance. His 1995 study with Clifford Swensen compared 194 people in long-distance relationships with 190 in close ones, and found no significant differences in satisfaction, intimacy, trust or how the relationship progressed (Guldner and Swensen, 1995). That’s the Guldner finding worth quoting.

"A third of couples break up within three months of reunion"

This one is real, and it’s easy to retell badly. Stafford, Merolla and Castle found that among long-distance dating couples who became geographically close, one-third ended within three months of reunion (Stafford, Merolla and Castle, 2006). Reunion there means ending up in the same place. It doesn’t necessarily mean sharing a flat.

The study also describes what changed when couples got together: less independence, more conflict and jealousy, and missing the novelty that distance had brought. That context matters far more than the fraction.

Anything with a year and no link

If a stats page gives you a percentage and a year but no journal, no DOI and no survey name, there’s nothing behind it you can read. The same goes for pages that link a journal’s homepage rather than the paper. And if you see Jiang and Hancock quoted with a success rate, check the abstract: it’s a 2013 diary study about intimacy, and no success rate appears there.

How to check a long-distance statistic yourself

It takes about two minutes, and it’ll save you a lot of late-night worrying.

1. Click through to the original. A journal page, a DOI or a government site. If the trail only leads to other stats pages, stop there.
2. Find out who was asked. Students on one campus are not married couples in Aberdeen.
3. Check where and when. A 2018 poll of Americans is not a British fact in 2026.
4. Ask what "long distance" meant. A partner in another household could live in the next street.
5. Ask who paid for it. A company selling to couples apart has a reason to publish a cheerful number.
6. Check the number measures the headline. "Rated their relationship highly" is not the same as "stayed together".

What the real research adds up to

Put the solid studies side by side and a fairly calm picture comes out. Several of them compared long-distance and close couples and found few differences in how happy, committed or close people felt. Couples apart seem to share more and idealise more, which feels lovely and can make the move to the same place a bit of a jolt. The months after closing the distance are a real risk worth planning for. And in Britain, the further apart couples lived, the more likely they were to be planning to change that.

None of that is a promise about any one relationship. For what it means in practice, read do long-distance relationships last?, and if you’re a student, the uni version looks at the campus study in more detail.

We keep the research KTL is built on, with links to the originals, on our research page. The long-distance hub has the practical side.

Questions people ask

What percentage of long-distance relationships work out?

There’s no reliable overall figure. The widely shared "58%" comes from a commercial poll commissioned by a sex-toy company, and its write-up never defined success. Peer-reviewed studies compare long-distance and close couples instead, and several found few differences in relationship quality. One study of a nationally representative sample of 870 people found break-up rates at follow-up were similar for both groups.

How many people are in long-distance relationships in the UK?

Nobody counts them directly. The 2021 Census found that 3.0% of people aged 16 and over in a legal partnership in England and Wales were not living in a couple, unchanged since 2011, but that includes married people living apart for any reason. Survey research on "living apart together" also includes couples who live close by, so it isn’t a count of long-distance couples either.

Is the 58% long-distance relationship statistic true?

It isn’t a research finding. It comes from a 2018 OnePoll survey of 1,000 American adults who had been in long-distance relationships, commissioned by KIIROO, a company that makes interactive sex toys. The write-up doesn’t define what "success" meant, the sample was American rather than British, and a company selling to couples apart paid for it. Treat it as marketing, not evidence.

Do long-distance relationships break up more often?

The better studies don’t show that. A study of a nationally representative sample of 870 people found that break-up rates at follow-up were similar for long-distance and close couples. The riskier stretch may come later: in a separate study, a third of long-distance dating couples who moved to the same place broke up within three months of reunion.
