How Many Couples Are Long Distance?
Long distance relationships are far more common than most people realize. The numbers suggest that millions of Americans are navigating the challenges of geographic separation at any given time.
3.5 Million Married Couples Live Apart
According to U.S. Census Bureau data cited by the Institute for Family Studies, roughly 3.5 million married couples in the United States live separately for reasons other than an impending divorce. This number has more than doubled since 1990, driven largely by dual-career households and job-market pressures that make it difficult for both partners to find work in the same city.
14 Million Couples in Long-Distance Relationships
When you include both married and unmarried couples, the Center for the Study of Long Distance Relationships estimates approximately 14 million couples in the US consider themselves to be in a long-distance relationship. This includes dating couples, engaged couples, and married couples living apart for work, military service, education, or other reasons.
These numbers represent a significant and growing segment of the population. The rise of remote work, online dating, and global mobility means that geographic separation is increasingly a normal chapter in many couples' stories rather than an unusual hardship.
Success and Survival Rates
This is the question everyone asks first: do long distance relationships actually work? The answer, supported by multiple peer-reviewed studies, is more encouraging than you might expect.
No Significant Difference in Satisfaction or Commitment
A foundational 1995 study by Gregory Guldner and Clifford Swensen compared 194 individuals in long-distance relationships with 190 individuals in geographically close relationships. Using a multivariate analysis of variance, they found no significant difference in relationship satisfaction, intimacy, trust, or commitment between the two groups. The amount of time couples spent together was not a reliable predictor of relationship quality.
LDR Couples Report Equal or Higher Intimacy
A 2013 study by Crystal Jiang and Jeffrey Hancock, published in the Journal of Communication, found that long-distance partners reported higher levels of intimacy and more meaningful self-disclosure than geographically close partners. The researchers attributed this to "behavioral adaptation" -- because LDR couples cannot rely on physical presence, they compensate with deeper, more intentional communication.
What "Success Rate" Actually Means
The commonly cited "58% success rate" for long distance relationships deserves context. This figure is comparable to success rates for geographically close relationships over similar time frames. In other words, distance alone does not significantly increase the likelihood of a breakup. The factors that predict LDR failure -- poor communication, lack of commitment, absence of a shared future plan -- are the same factors that predict failure in any relationship.
Laura Stafford, a leading researcher on long-distance relationships and author of Maintaining Long-Distance and Cross-Residential Relationships, has noted that "most studies have found equal or even higher levels of satisfaction, commitment, and trust in long-distance dating relationships compared to geographically close ones." The key qualifier: this applies to couples who actively maintain the relationship, not to all LDRs by default.
Average Duration of Long-Distance Periods
How long does the average long-distance relationship last? The data reveals meaningful patterns about duration, distance, and visit frequency.
Key Duration and Distance Statistics
Data from the Center for the Study of Long Distance Relationships, founded by Dr. Gregory Guldner of Stanford Medical School and Purdue University, provides some of the most specific data points on LDR logistics:
- Average LDR duration: 2.9 years
- Average distance between partners: 125 miles
- Average visit frequency: 1.5 times per month
The Eight-Month Threshold
Multiple sources suggest that if a long-distance relationship can survive past the eight-month mark, the relationship becomes significantly more stable. This aligns with attachment research suggesting that couples who develop secure communication patterns and trust during the initial difficult months build a foundation that sustains them through the longer stretches of separation.
It is worth noting that "duration" statistics include both relationships that end in breakup and those that successfully transition to geographic closeness. A relationship lasting 2.9 years before closing the gap is fundamentally different from one lasting 2.9 years before dissolving. The number alone does not tell the full story.

Communication is often cited as the most important factor in LDR success. But how much do long-distance couples actually communicate, and what methods work best? The research offers some surprising answers.
Texting Predicts Satisfaction in LDRs (But Not Close-Proximity Couples)
A 2021 study by Holtzman, Kushlev, Wozny, and Godard surveyed 647 participants and found that more frequent and responsive texting predicted significantly greater relationship satisfaction among long-distance couples -- but this effect was not present in geographically close couples. In other words, texting matters more when you cannot see your partner in person.
Video Calls: Not the Silver Bullet You'd Expect
The same Holtzman et al. study found that video call frequency was not significantly linked to relationship satisfaction in either long-distance or close-proximity relationships. This challenges the common assumption that video calling is the most important communication tool for LDR couples. The data suggests that the content and responsiveness of communication matters more than the medium.
| Communication Method | LDR Usage vs. Close Couples | Impact on LDR Satisfaction |
|---|---|---|
| Text messaging | Higher frequency in LDRs | Significant positive effect |
| Voice calls | Higher frequency in LDRs | Significant in close couples, not LDRs |
| Video calls | Higher frequency in LDRs | Not significantly linked to satisfaction |
| Communication responsiveness | Equal importance | Strong positive effect |

LDR Partners Communicate More Deeply
The Jiang and Hancock diary study asked dating couples to log their daily interactions across all communication channels for a week. Long-distance partners reported higher levels of self-disclosure and more adaptive communication than geographically close partners. They shared more about themselves, discussed more meaningful topics, and were more intentional about maintaining intimacy through their interactions.
What This Means for LDR Couples
The research suggests a counterintuitive conclusion: the specific communication tool matters less than how you use it. Quick, responsive texts throughout the day may do more for your relationship than a nightly video call where both people are distracted. What matters most is consistency, responsiveness, and depth -- asking real questions, sharing genuine feelings, and making your partner feel heard. Tools like a couples app that prompts deeper conversation can help bridge the gap between surface-level check-ins and meaningful connection.
Trust and Jealousy Statistics
Trust is the currency of a long-distance relationship. Without the reassurance of daily physical presence, LDR couples must build and maintain trust through communication alone. What does the research say about how well they do?
Relational Uncertainty Drives Jealousy -- Not Distance Itself
A study by Dainton and Aylor (2001) examined jealousy, trust, and maintenance behaviors across 311 individuals in both long-distance and geographically close relationships. They found that relational uncertainty -- not geographic distance -- was the primary driver of jealousy. Couples who maintained low uncertainty about their relationship status and commitment experienced comparable levels of trust regardless of distance.
However, the study found that LDR couples with little in-person contact reported significantly more relational uncertainty than those who saw each other regularly, highlighting the importance of consistent visit schedules.
Infidelity: Not Clearly Higher in LDRs
The assumption that long-distance relationships are more prone to cheating is not clearly supported by the data. Some surveys report infidelity rates around 22% for LDR partners, while general population infidelity rates are estimated at 15-20% for married couples. Research from Brigham Young University found an interesting nuance: couples at moderate distances (around 100 miles) may face higher risk than those who are either very close or very far apart -- suggesting that ambiguity about the relationship's status may matter more than distance.
The takeaway from the trust and jealousy research is clear: distance creates conditions where jealousy can thrive, but it does not cause jealousy. The couples who struggle most with trust are those who leave their relationship status ambiguous, communicate infrequently, or avoid difficult conversations about commitment. Couples who proactively address uncertainty through honest check-in conversations maintain comparable levels of trust to geographically close couples.
Reunion Success and Failure Rates
One of the most striking findings in LDR research is what happens after the distance ends. The transition from long-distance to same-city is not the fairy-tale ending many couples expect.
One-Third of LDR Couples Break Up Within 3 Months of Reuniting
A widely cited 2007 study by Laura Stafford and Andy Merolla found that long-distance relationships were more stable than geographically close relationships as long as the partners remained separated -- but approximately one-third of LDR couples broke up within three months of becoming geographically close.
The study identified idealization as the primary culprit. During separation, LDR partners tend to form idealized images of each other and the relationship. When reunited, the gap between the idealized version and the everyday reality of living near each other caused disillusionment.
What Predicts a Successful Reunion
The same Stafford and Merolla study identified factors that predicted whether an LDR couple would survive the transition to geographic closeness:
- Moderate (not extreme) idealization during separation predicted better outcomes. Some positive framing of the partner is healthy; deifying them is not.
- More frequent visits during the LDR period predicted smoother transitions, likely because regular in-person contact kept expectations grounded in reality.
- Shorter gaps between visits reduced the buildup of idealized perceptions.
The researchers concluded that couples who "ground their romanticized perceptions in objective facts about the other individual" tend to have more successful reunions.
The Reunion Paradox
This data reveals a paradox at the heart of long-distance relationships: the same idealization that helps couples endure the separation (seeing the relationship through rose-colored glasses, focusing on the positives, romanticizing visits) can undermine the relationship when the distance ends. The most successful LDR couples balance optimism with realism -- they cherish their time together while acknowledging that daily life includes mundane moments, minor irritations, and imperfect days.
Build Habits That Survive the Reunion
Daily questions and weekly check-ins create communication patterns that work whether you're 1,000 miles apart or on the same couch.
Try Connected FreeCollege Long-Distance Relationships
College students represent one of the largest populations of long-distance relationships, as couples who formed in high school attempt to maintain their connection across separate campuses. The data on college LDRs reveals both how common they are and how they differ from LDRs in other life stages.
34% of College Students in Relationships Are Long-Distance
A 2021 study by Beckmeyer, Herbenick, and Eastman-Mueller, published in the Journal of American College Health, surveyed 2,075 romantically involved college students and found that 34.2% were in long-distance relationships. The rate was highest among first-year students, consistent with the pattern of high school couples entering college at different schools.
College LDRs Are No More Likely to Break Up (Initially)
Research on college relationship dissolution found that in the first three months, long-distance college relationships were no more likely to break up than geographically close ones. However, after the initial period, LDRs face increasing pressure as partners develop independent social lives, new friendships, and separate daily routines.
The "Turkey Drop" Phenomenon
College counselors have long observed a pattern called the "turkey drop" -- a spike in LDR breakups when college freshmen return home for Thanksgiving break. While the term is informal and not derived from a specific study, it reflects a well-documented pattern in college relationship research: the first holiday break forces couples to confront the gap between their expectations and the reality of how much each partner has changed in the first few months of college. For many couples, this is the first real test of whether the relationship can survive the diverging lives that college creates.
Military Long-Distance Relationships
Military families face some of the most demanding long-distance circumstances: deployments are often to combat zones, separation can last 12-18 months, communication may be limited or unreliable, and the emotional toll of danger adds a layer of stress that civilian LDRs rarely face. The research on military relationships provides important data on how extreme distance and uncertainty affect partnerships.
12+ Month Deployments Increase Divorce Risk by 28%
A landmark 2013 study by the RAND Corporation analyzed data from 462,444 enlisted service members who married while serving between March 1999 and June 2008. The findings were significant:
- Deployments of 12+ months to combat zones increased divorce risk by 28% within the first three years of marriage
- Longer deployments (18 months vs. 12 months) correlated with even greater divorce risk
- Female service members faced the highest risk, with up to a 50% chance of divorce within five years when deployed to combat zones
- 97% of military divorces occurred after the service member returned from deployment, not during it
Protective Factors for Military Marriages
The RAND study also identified factors that reduced divorce risk among military couples:
- Having children was associated with lower divorce rates during deployment
- Couples who married after 9/11 (and were therefore aware of deployment risks before marrying) had lower divorce rates than those who married before the conflicts began
- Deployment frequency (how many times, not just how long) was identified as a key stressor that induced the greatest level of marital conflict
The military data highlights an important point about the reunion challenge: the vast majority of military marriages that end do so after the deployment, not during it. This mirrors the civilian LDR research showing that the transition from separation to proximity is one of the most vulnerable periods for a relationship.

Technology's Impact on LDR Success
Modern technology has fundamentally changed what it means to be in a long-distance relationship. Couples who would have relied on letters and expensive long-distance phone calls a generation ago now have video calling, instant messaging, shared apps, and social media. What does the research say about how these tools affect relationship outcomes?
Multiple Communication Channels Increase Intimacy
The Jiang and Hancock (2013) diary study asked LDR and geographically close couples to track their daily interactions across six media: face-to-face, phone calls, video chat, texting, instant messenger, and email. LDR couples who used multiple communication channels reported higher intimacy than those who relied on a single medium. The variety itself seemed to matter -- different channels serve different emotional functions, from quick check-ins (text) to deeper conversations (phone) to feeling physically present (video).
Responsiveness Matters More Than Method
The Holtzman et al. (2021) study found that across all communication methods, responsiveness -- how quickly and thoughtfully partners replied to each other -- was a stronger predictor of relationship satisfaction than the communication method itself. LDR couples who maintained responsive, engaged texting throughout the day reported higher satisfaction than those who scheduled longer but less responsive video calls.
The Role of Couples Apps
While the research on technology and LDRs has largely focused on general communication tools, the emergence of purpose-built couples apps represents a new category. Tools like Connected address a gap that general communication tools miss: they do not just provide a channel for conversation, they provide the content -- communication assessments, daily questions, and guided check-ins -- that facilitates the kind of deep, intentional communication that research consistently links to LDR success. For couples who struggle with the "what do we talk about beyond logistics" problem, structured prompts can be the difference between a stale routine and a growing connection.
Online Dating Has Expanded the LDR Pool
According to Pew Research Center (2023), 30% of US adults have used an online dating app, and one in five partnered adults ages 18-29 met their current partner online. This has naturally expanded the pool of long-distance relationships, as online dating removes the geographic constraint from initial partner selection. Couples who meet online are more likely to start as long-distance and must navigate the transition to in-person connection from the outset.
The Research Is Clear: Intentional Communication Wins
Connected gives you a daily question, weekly check-ins, and relationship insights -- the structured depth that LDR research says matters most.
Download Connected FreeTips Based on What the Data Shows
The research on long-distance relationships points to specific, actionable strategies that are consistently linked to better outcomes. Here is what the data suggests you should focus on.
1. Prioritize Communication Quality Over Quantity
The Holtzman et al. (2021) study found that communication responsiveness predicted satisfaction more reliably than communication frequency. You do not need to be in constant contact -- you need to be genuinely present when you are in contact. A thoughtful, engaged 20-minute conversation outperforms a distracted two-hour video call. For conversation starters that go beyond surface-level, try relationship check-in questions.
2. Use Multiple Communication Channels
Jiang and Hancock (2013) found that variety in communication methods was linked to higher intimacy. Mix texting, voice memos, video calls, handwritten letters, shared apps, and photo sharing. Different channels serve different emotional needs, and monotony in communication can mirror monotony in the relationship.
3. Maintain Realistic Expectations (Especially Before Reunion)
Stafford and Merolla (2007) demonstrated that extreme idealization during separation predicted instability upon reunion. Allow your partner to be a real, imperfect human during phone calls and visits. Embrace the boring moments. The couples who survived the transition to geographic closeness were those who maintained grounded, realistic perceptions of each other throughout the distance.
4. Visit Regularly and Keep Visits Grounded
Research consistently links more frequent visits to better outcomes. Stafford and Merolla found that shorter gaps between visits reduced idealization and predicted smoother reunions. When you visit, resist the urge to make every moment special -- include ordinary activities like grocery shopping, cooking together, and quiet evenings. These mundane moments keep your expectations calibrated to reality.
5. Reduce Relational Uncertainty
Dainton and Aylor (2001) found that uncertainty -- not distance -- drives jealousy. Be explicit about your commitment, your future plans, and your feelings. Have the uncomfortable conversations about where you stand. A clear, shared understanding of the relationship's trajectory is one of the strongest protections against the jealousy and insecurity that distance can amplify.
6. Have a Defined End Date
Across multiple studies, having a clear plan for closing the gap is one of the most consistent predictors of LDR success. The plan does not need to be finalized tomorrow, but both partners need to be actively working toward the same goal. Couples without an end date for the distance face significantly more uncertainty and lower relationship satisfaction. For more practical strategies, see our complete LDR tips guide.
"The couples who make it through long distance are not the ones who avoid difficulty. They are the ones who use the distance as a training ground for the communication skills, trust, and intentionality that every relationship needs."
Frequently Asked Questions
What percentage of long distance relationships work out?
Research suggests that approximately 58-60% of long-distance relationships succeed long-term. A foundational study by Guldner and Swensen (1995) found no significant difference in satisfaction or commitment between long-distance and geographically close couples. The success rate depends heavily on factors like having a defined end date for the distance, communication quality, and mutual commitment.
How many couples in the US are in long distance relationships?
Approximately 14 million couples in the United States are in long-distance relationships, according to the Center for the Study of Long Distance Relationships. The U.S. Census Bureau reports that roughly 3.5 million married couples live separately for reasons other than divorce -- a number that has more than doubled since 1990.
What is the average duration of a long distance relationship?
The average long-distance relationship lasts approximately 2.9 years. LDR partners typically live about 125 miles apart and see each other approximately 1.5 times per month. These averages include both relationships that eventually close the gap and those that end in breakup.
Do long distance relationships have higher breakup rates?
No. Multiple studies, including Guldner and Swensen (1995), have found that long-distance relationships are no more likely to break up than geographically close relationships during the relationship itself. However, Stafford and Merolla (2007) found that about one-third of LDR couples break up within three months of reuniting, due to the disruption of idealized perceptions.
Are long distance relationships more likely to involve cheating?
The data does not clearly support this assumption. Some surveys report infidelity rates around 22% for LDR partners, comparable to rates in geographically close relationships. Research from Brigham Young University found that couples at moderate distances may face higher risk than those who are very close or very far apart, suggesting that ambiguity about relationship status matters more than physical distance.
How often should long distance couples communicate?
Research by Holtzman et al. (2021) found that communication quality and responsiveness matter more than frequency. Responsive texting throughout the day predicted higher satisfaction in LDRs, while video call frequency alone was not significantly linked to satisfaction. Most successful LDR couples maintain a mix of daily texting, regular calls, and shared activities.
What percentage of college relationships are long distance?
A 2021 study published in the Journal of American College Health found that 34.2% of romantically involved college students were in long-distance relationships. The rate was highest among first-year students. Approximately 75% of college students report having been in an LDR at some point during their college years.
What is the military divorce rate related to deployment?
A 2013 RAND Corporation study of 462,444 enlisted service members found that deployments of 12+ months to combat zones increased divorce risk by 28% within the first three years of marriage. Female service members faced up to a 50% chance of divorce within five years when deployed. Notably, 97% of military divorces occurred after return from deployment.
Does technology help long distance relationships succeed?
Yes. Research by Jiang and Hancock (2013) found that LDR couples who used multiple communication channels reported higher intimacy levels. However, Holtzman et al. (2021) found that the medium matters less than the quality -- responsive texting predicted satisfaction more reliably than video call frequency. Technology works best when it facilitates meaningful conversation, not just visual contact.
What happens when long distance couples finally move to the same city?
Stafford and Merolla (2007) found that about one-third of LDR couples break up within three months of becoming geographically close. Extreme idealization during separation and longer gaps between visits predicted instability upon reunion. Couples who maintained realistic expectations and visited frequently had smoother transitions. The key is continuing the intentional communication habits built during the LDR rather than assuming proximity will handle everything.
What the Numbers Really Tell Us
The statistics paint a clear picture: long distance relationships are common, survivable, and in many cases, capable of producing relationships with deeper communication and stronger commitment than geographically close ones. But the data also reveals that success is not automatic -- it requires intentional effort, honest communication, regular visits, and a shared plan for eventually closing the gap.
The most important statistic might be this one: the factors that predict LDR success are the same factors that predict success in any relationship. Communication quality. Mutual commitment. Emotional honesty. Realistic expectations. A shared vision for the future. Distance does not create new problems so much as it amplifies existing ones -- and it rewards couples who are willing to do the work.
If you are in a long-distance relationship right now, the numbers are on your side -- as long as you are willing to be intentional about it. Start with one change today: ask a deeper question, schedule the next visit, or download a tool like Connected that makes daily connection easier. The distance is temporary. The habits you build through it are not.
