Relationship Statistics (2026)
"Relationship statistics" is the broadest topic on this page, spanning who is single and why, how couples meet, how long-distance relationships hold up, and what predicts whether a relationship lasts. Because it's broad, we've focused on a handful of large, well-designed studies rather than trying to cover every possible angle shallowly.
Two sources anchor most of the current data here: Pew Research Center's large, nationally representative surveys on singlehood and online dating, and a set of peer-reviewed studies specifically on long-distance relationship stability, which produced a genuinely counterintuitive finding — long-distance couples are often more stable while separated than while reunited.
As with the other pages in this collection, every statistic below links to its original source.
Key statistics
- 30% of U.S. adults are single — not married, not living with a partner, and not in a committed relationship.
- Among adults under 30, 47% are single, compared with 21% of 30- to 49-year-olds.
- Of single Americans, 57% are not currently looking for a relationship or casual dates; 42% are looking for some kind of romance.
- 30% of U.S. adults say they've ever used a dating site or app; among those looking for a relationship, 45% used one in the past year.
- 1 in 10 partnered U.S. adults met their current partner through a dating site or app — rising to 1 in 5 among partnered adults under 30.
- 42% of U.S. adults say dating apps have made finding a long-term partner easier; 22% say they've made it harder.
- Long-distance dating couples show greater relational stability than geographically close couples — as long as they remain apart.
- About half of long-distance couples transition to living near each other; the other half end the relationship while still separated.
- Among long-distance couples who do reunite, about one-third break up within 3 months of closing the distance.
- Reunion is linked to a loss of autonomy, increased conflict and jealousy, and new time-management strain — not just excitement.
- 36% of ever-married U.S. adults describe their marriage as 'very happy,' a figure that's held steady since this survey began in 1972.
- Couples who stayed together 6 years after their wedding responded to their partner's small bids for connection 86% of the time, versus 33% for couples who divorced.
Relationship Statistics (General)
Before looking at couples, it's worth establishing how many U.S. adults are in a relationship at all, and what share are actively looking for one.
30% of U.S. adults are single — defined as not married, not living with a partner, and not in a committed romantic relationship.
This nationally representative figure varies sharply by age: 47% of adults under 30 are single, compared with 21% of those ages 30-49 and 30% of those 50 and older, forming a U-shaped pattern across the adult lifespan.

Of those actively looking, the survey found roughly 22% are open to either a committed relationship or casual dating, 13% want only a committed relationship, and 7% want only casual dating — meaning 'looking to date' isn't a single, uniform category.

Online dating has gone from a niche behavior to a mainstream path to relationships in under two decades, and Pew Research has tracked this shift closely.
1 in 10 partnered U.S. adults met their current significant other through a dating site or app — rising to 1 in 5 among partnered adults under 30.
This is based on a survey of 6,034 U.S. adults conducted in mid-2022. The sharp age gradient shows online dating has become disproportionately the entry point for younger couples' relationships compared with older ones.

Views split further by gender and prior experience: people who have used dating apps themselves, and those currently in a relationship that started online, tend to rate the format more positively than the general population.

Long-distance relationship research produced one of the more surprising, well-replicated findings in this entire collection: distance itself isn't the main threat — reunion is.
Long-distance dating couples show greater relational stability than geographically close couples — but only as long as they remain separated.
Researchers tracked couples through the transition from long-distance to living near each other and found the stability advantage long-distance couples showed while apart didn't carry over automatically once they closed the distance.

Reunion introduces its own strain: researchers linked it to a loss of individual autonomy, increased exposure to previously unknown (and sometimes unwelcome) information about a partner, new time-management conflicts, and heightened jealousy — all factors absent while the relationship existed primarily through scheduled contact.

Two very different research traditions — a long-running national survey and decades of observational couples-lab research — both point to specific behaviors, not raw relationship length, as the strongest satisfaction signal.
36% of ever-married U.S. adults describe their marriage as 'very happy,' a figure that has held roughly steady since this survey began tracking it in 1972.
This stability contrasts with more dramatic shifts elsewhere in relationship statistics (falling marriage rates, later marriage ages), suggesting the experience of those who do marry has not shifted as much as the decision of whether or when to marry at all.

A 'bid' is any small attempt to get a partner's attention or support. This finding is one of the most frequently cited in relationship-satisfaction research because the gap between the two groups (86% vs. 33%) is unusually large for behavioral research of this kind.

Expert quotes
“Long-distance couples often look more stable on paper, but that stability can be an artifact of the distance itself — reduced conflict, fewer chances for friction, more idealization of the partner. The real test often comes at reunion, not during the separation.”

How we built this page
- Singlehood and online dating figures came from large, nationally representative Pew Research Center surveys with disclosed sample sizes and field dates.
- Long-distance relationship statistics came from peer-reviewed, longitudinal communication-studies research rather than the many uncredited '58% success rate'-style figures that circulate online without a traceable original source — we excluded those where we could not verify the underlying study.
- Where a widely repeated relationship statistic lacked a clear primary source we could verify, we left it off this page rather than repeating it.
- This page was last checked for broken links and outdated figures on 2026-07-21.
