Most LDR statistics floating around the internet trace back to one or two small studies, repeated until they sound canonical. This page is our attempt to separate what's reasonably well-established from what's been over-extrapolated.
How common are long-distance relationships?
Estimates put the share of adult dating and married couples in long-distance relationships in the US at roughly 3-4 million couples at any given time, though numbers vary by definition (geographic separation, military deployment, work-related). Among college students, the share in LDRs has been reported around 25-50% at different points during their studies — depending heavily on the institution and how "long-distance" is defined.
Online-origin relationships now make up roughly 40% of new heterosexual relationships and over 60% of new same-sex relationships in the US, per Rosenfeld and colleagues' work tracking how Americans meet. A meaningful fraction of online-origin relationships start at a distance.
The "58% success rate" — does it hold up?
You'll see "58% of long-distance relationships succeed" all over the LDR internet. The number traces back to a Center for the Study of Long Distance Relationships survey from the early 2000s. The center is no longer active, the sample was self-selected and small, and "success" was defined as the relationship still being intact at the time of follow-up — which is not the same as a healthy or lasting outcome.
Honest version: we don't have a reliable population-level success rate for LDRs. What we do have is decent comparative research showing LDR and geographically close couples report similar relationship satisfaction, and decent research showing that the period right after closing the distance is the highest-risk phase.
Satisfaction and stability
- Across multiple studies (Stafford and Reske, Kelmer et al., Jiang and Hancock), long-distance couples report comparable or slightly higher relationship satisfaction, intimacy, and trust than geographically close couples. This is consistent enough across samples to take seriously.
- The likely explanation: distance forces more intentional communication and removes everyday friction, which inflates satisfaction during the LDR phase. The friction returns when partners move in together.
- About one in three couples who close the distance break up within three months of reunion (Stafford, Merolla, Castle — a much-cited finding). The reasons cluster around: discovering daily-life incompatibilities that distance hid, loss of the idealization the distance produced, and difficulty integrating into shared social and family networks.
Communication patterns
- Long-distance couples communicate less frequently than co-located couples but spend more time on each interaction. The asymmetry is consistent across studies.
- Daily communication is common but not necessary for satisfaction. The predictor of trouble is mismatch between partners' preferred contact frequency, not the frequency itself.
- Video calling correlates with higher relationship quality than text-only or voice-only communication, controlling for relationship length and commitment level. Plausible but possibly confounded — happier couples may simply video-call more.
- Couples who report regular "idealization" (overly positive perception of the partner) during the LDR phase show higher dissolution rates after CTD. The mechanism isn't surprising: reality is a downgrade from the idealized version.
Demographics
- Average reported distance in non-military adult LDRs is 125-175 miles in survey data, though the distribution has a long tail — many couples are several thousand miles or international.
- Average reported time apart per LDR phase is around 14 months. The "typical" LDR is more than a year, less than three.
- The most common reasons for LDRs in adults: career or job placement, education, military service, and meeting online. The mix has shifted significantly toward "met online" over the last decade.
Visits
- Most LDR couples visit each other every 3-6 weeks where geography and budget allow. Couples who go more than 3 months between visits report markedly higher relationship distress.
- The first in-person meeting from online-origin relationships is rated "matched expectations" by roughly half of respondents, "exceeded expectations" by about a quarter, and "disappointed" by the remaining quarter. Subsequent in-person trajectory depends more on follow-through than first-impression.
Mental health
- Higher rates of self-reported depression and anxiety in LDR samples than non-LDR samples — but the effect size is smaller than popular framing suggests, and reverse causation matters (people with anxiety or depression may be more likely to end up in LDRs for various reasons).
- Loneliness is the most consistently elevated outcome. About half of LDR partners report experiencing significant loneliness during their LDR — not all the time, but as a recurring feature.
- The mental health of the partner who is left behind when the other relocates ahead of CTD tends to be worse than the partner who moves first. The partner who moves is doing something; the partner left behind is waiting.
The CTD dropoff
The single most actionable statistic about LDRs is this: closing the distance is the highest-risk phase of the relationship, not the LDR phase itself. The Stafford studies put it at ~33% breakup within three months of moving in together. Other estimates run somewhat lower.
The lesson is not "don't close the distance" — it's "treat the CTD transition as a project, not as the resolution." Couples who do trial runs, who have honest conversations about expectations before the move, and who give themselves 6-12 months to renegotiate the relationship after the move tend to fare meaningfully better. More on this transition.
What we don't know
- The actual base-rate success of LDRs across the general population. The data we have is over-weighted toward college students and self-selected survey respondents.
- Outcomes for online-origin LDRs specifically — most large studies predate the smartphone era or treat online-origin and offline-origin LDRs the same way.
- The effect of newer communication technologies (touch bracelets, AR, persistent video) on LDR outcomes. Anecdotal data only.
- Outcomes for same-sex, polyamorous, and non-traditional LDRs. The literature is dominated by monogamous heterosexual samples.
