What Percentage of Relationships Start Online? (2026)
✓ Last verified: 2026-07-06There is no single honest answer, because the number depends on two things: whether you mean “met online” broadly or “met on a dating app” specifically, and whether you count newly formed couples or every partnered adult of any era. Pin those down and the real figures are clear. The clean headline you see on affiliate sites (“X% of relationships start online”) is almost always a number without a source.
Here are the figures that do have sources, and what each one actually measures.
The flagship figure: about 39%
Stanford’s “How Couples Meet and Stay Together” survey found that about 39% of heterosexual US couples who got together in 2017 met online, making the internet the single most common way couples meet. Online meeting overtook meeting through friends around 2013 (Rosenfeld, Thomas and Hausen, PNAS 2019). For same-sex couples it was even higher, roughly 65%.
Two things this figure includes that people miss: it is “met online” in the broad sense (dating apps, yes, but also social media, DMs, online gaming, and online communities), and it is the share of couples who formed in that specific year, not of all couples alive today. It is also 2017 data. Later waves of the same study track whether those 2017 couples stayed together, not how a fresh cohort met, so no newer nationally representative “how new couples meet” cross-section has replaced it.
The narrower figure: about 10%
Pew Research Center asks a tighter question and gets a smaller number: 10% of all partnered US adults say they met their current spouse or partner on a dating site or app. Among partnered adults under 30, that rises to 20% (Pew, 2023).
This looks like it contradicts the 39%, and it does not. The two measure different things:
| Stanford (~39%) | Pew (~10%) | |
|---|---|---|
| Who is counted | Couples formed in 2017 | All partnered adults, any era |
| Scope of “online” | Any online venue | Dating app specifically |
| So the denominator includes | Only recent couples | Marriages from the 1970s onward |
Pew’s number is diluted by every relationship that began before dating apps existed. Stanford’s is a snapshot of one recent year. Both are correct; they answer different questions.
The trend line: it is climbing
The share of dating-app users who get a real relationship out of it is rising. SSRS, an independent survey firm, found that half (50%) of Americans who have ever used a dating app say they have been in a committed relationship with someone they met that way, up from 42% in 2024 (SSRS, 2026). Adoption is broad and steady: around 30% (Pew, 2023) to 37% (SSRS, 2026) of US adults have ever used a dating site or app.
The gap by orientation is large. Partnered LGB adults are far more likely than straight adults to have met their partner via a dating app: 24% versus 9% (Pew, 2023), which fits the pattern that online dating helps most where the offline pool is thinnest.
What displaced what
The rise of online meeting came out of the decline of the old channels. Meeting through mutual friends fell from about a third of couples in the mid-1990s to roughly 20% by 2017; meeting through family dropped to around 7% (Stanford). The apps did not add to how people meet so much as replace the friend-of-a-friend introduction that used to do this work.
Numbers to be skeptical of
This topic is a magnet for stats with no origin. Treat these with caution:
- “27% of couples who married in 2025 met on apps” and similar clean current-year figures circulate on vendor and affiliate blogs with no traceable primary source. There is no rigorous survey behind them.
- “More than a third of US marriages began online” traces to a real PNAS paper (Cacioppo et al., 2013), but that study was commissioned by eharmony, its lead author was a paid eharmony advisor, and it used 2005 to 2012 marriage data that is now well over a decade old.
- Any single “1 in 5 relationships start online” headline stated as current fact is definition-dependent guesswork.
Bottom line
If someone wants one number, give them two with their labels: about 39% of US couples who formed in 2017 met online (the most common way couples now meet), and about 10% of all partnered adults met specifically on a dating app. The direction is not in doubt, online meeting won, but the exact percentage always depends on what you are counting. For the fuller picture of what that shift did to dating, see modern dating culture, and for whether the shift was good or bad, is online dating bad.
