You searched for cheating statistics because you need answers, not vague reassurances. Here is the short version: roughly 20% of married men and 13% of married women in the U.S. admit to sexual infidelity, according to the General Social Survey. One in three Americans say they have cheated on a partner at some point (YouGov, 2024). When emotional affairs are included, those numbers climb sharply.

Those percentages represent millions of marriages and relationships under strain right now. If you suspect something is off in your relationship, the data suggests your instincts may be grounded in reality. Research shows that 85% of women who suspect their partner of cheating are correct.

This article compiles 50+ cheating statistics from peer-reviewed studies, national surveys, and research institutions. Every number has a real source. You will find infidelity rates broken down by gender, age, relationship type, and geography, along with data on why people cheat, how affairs get discovered, and what happens to relationships afterward.

If your concern is specifically about dating apps, CheatScanX scans 15+ platforms in minutes. One search can tell you whether a partner has active profiles on Tinder, Bumble, Hinge, and more.


How Common Is Cheating? Overall Infidelity Rates

The answer depends on how you define cheating and who you ask.

The General Social Survey (GSS), run by NORC at the University of Chicago, is the gold standard for U.S. infidelity data. Their most recent data (2021-2022) shows that 13% of ever-married prime-age adults reported extramarital sex, down slightly from 14% during the 2010-2018 period.

The breakdown by gender:

A YouGov poll found even higher self-reported rates: roughly one in three Americans (33%) admit to cheating on a partner or spouse at some point.

The gap between these numbers reflects differences in methodology. The GSS asks specifically about extramarital sex during marriage. YouGov's question covers all relationship types and all forms of infidelity.

Physical vs. Emotional Infidelity

When you expand the definition beyond physical sex, the numbers change significantly. The Institute for Family Studies iFidelity survey found these breakdowns among ever-married adults who reported any infidelity:

Type of AffairPercentage
Both sexual and emotional10%
Strictly emotional7%
Strictly physical5%

A separate study of 5,783 reports by Dr. Kathy Nickerson found that women's affairs are overwhelmingly emotional in nature: 79.8% of women who had an affair reported it was both physical and emotional, compared to 66.5% of men. Men were twice as likely to have a strictly physical affair (21.4% vs. 10.4%).

If you are watching for warning signs of an emotional affair, the signs of emotional cheating through texting can be subtle but trackable.

Is Cheating Getting More Common?

Despite social media making infidelity more visible (TikTok alone has 350+ million posts about cheating), the actual data does not show a dramatic increase. The Survey Center on American Life found that General Social Survey rates of extramarital sex have remained relatively stable over the past two decades.

Male infidelity has actually decreased slightly, from 21% in the 1990s to roughly 11% in 2021-2022 among prime-age adults. Female infidelity has remained steady at around 14% during the same period with minor fluctuations.

The perception of an "infidelity epidemic" appears driven by greater visibility and openness in discussing cheating, not by actual increases in behavior.

Cheating Statistics by Gender: Who Cheats More?

Men cheat more than women overall, but the gap is more complicated than the headline numbers suggest.

Overall Gender Gap

The GSS data shows a consistent 7-percentage-point gap: 20% of men vs. 13% of women. This gap has narrowed over the past two decades, primarily because male infidelity rates have declined while female rates have held steady.

Women's infidelity rates have increased by approximately 40% over the past 20 years when measured across all age cohorts, though the overall rate remains lower than men's.

The Age Reversal

One of the most striking findings from the GSS data: among adults ages 18 to 29, women cheat at slightly higher rates than men (11% vs. 10%). This pattern is unique to the youngest married age group and reverses sharply after age 30.

The Institute for Family Studies reports that the gender gap grows steadily wider with age:

Age GroupMenWomenGap
18-2910%11%Women +1
30-34HigherLowerMen lead
50-5928%17%Men +11
60s24%16%Men +8
70s26%DeclineMen +15+
80+24%~6%Men +18

The peak cheating age for men is in their 70s (26%). For women, it is in their 60s (16%). If you are concerned about a spouse on a specific platform, the husband cheating on Tinder signs are well-documented.

Why the Gender Difference?

Research points to several factors beyond opportunity:

If you are concerned about your husband's behavior, these signs your husband is cheating on his phone are specifically tracked by research.

Cheating Statistics by Age Group

Age is one of the strongest predictors of infidelity, though not in the way most people expect.

Young Adults (18-29)

Peak Cheating Years (30-59)

Infidelity rates climb through the 30s and 40s, peaking in the 50s:

This tracks with relationship research. Marriages between 7 and 15 years in duration face the highest infidelity risk, overlapping significantly with the 30-50 age range.

Older Adults (60+)

Cheating does not stop with age, particularly for men:

The gender gap in cheating is widest among the oldest cohort: an 18-percentage-point difference between men and women ages 80 and older.


Cheating by Relationship Type and Demographics

Infidelity is not evenly distributed across the population. Certain demographic factors correlate strongly with higher or lower rates.

By Race and Ethnicity

The GSS data reveals significant differences:

Race/EthnicityOverall RateMen
Black22%28%
White16%20%
Hispanic13%16%

These differences persist after controlling for other demographic variables, though researchers note that varying cultural attitudes toward disclosure may influence self-reporting.

By Family Background

People who did not grow up in intact families (both biological parents together) cheat at higher rates: 18% vs. 15% for those from intact families (GSS). This 3-point gap suggests that exposure to relationship instability during childhood may normalize infidelity or reduce relationship skills.

By Religious Attendance

Adults who rarely or never attend religious services report significantly higher infidelity rates than regular attendees. The GSS data consistently shows this pattern across multiple survey years.

By Education

Education level shows surprisingly little effect:

The "some college" group has a slightly elevated rate, but the differences are modest. Education does not appear to be a meaningful protective factor against infidelity.

By Relationship Duration

Longer relationships face compounding risk:

These numbers underline that infidelity is often a symptom of relationship erosion, not a random event.


Why People Cheat: The Data Behind the Reasons

Understanding why people cheat matters because it reveals patterns. Here are the most commonly reported reasons, broken down by research.

Top Reasons by Gender

Women who cheat cite:

  1. Emotional dissatisfaction — 70%
  2. Feeling unappreciated or undesired — 40%
  3. Sexual dissatisfaction — 35%
  4. Low self-esteem or need for validation — cited frequently in multiple studies

Men who cheat cite:

  1. Sexual dissatisfaction — 50%
  2. Wanting more variety — 44%
  3. Opportunity (not dissatisfaction) — 27%
  4. Emotional disconnection — 20%

The Role of Opportunity

One of the most underappreciated findings: 27% of cheaters say opportunity, not dissatisfaction, was the main trigger. This means more than 1 in 4 affairs happen not because the relationship was failing, but because the opportunity presented itself.

This has direct implications for signs your partner is cheating. The "everything seemed fine" experience that many betrayed partners describe is consistent with this data. A significant minority of cheaters report being relatively satisfied with their primary relationship.

Emotional Disconnection as the Common Thread

Across multiple studies, 60% of cheaters reported feeling emotionally disconnected from their spouse before the affair began. This is the single most consistent predictor of infidelity across genders.

Half of cheaters in long-term marriages (10+ years) cited boredom as a key factor, suggesting that routine and emotional neglect create vulnerability over time.

Narcissism and Personality Factors

Personality research adds another layer. Narcissistic personality traits are present in 30% of self-reported cheaters compared to 15% of non-cheaters. People with higher narcissism scores are twice as likely to engage in infidelity, according to multiple psychological studies.

Research from the Journal of Sex Research (2021) found that relationship satisfaction, love, desire, and relationship length were the strongest predictors of infidelity using machine learning analysis.

Technology as an Accelerant

The role of technology deserves specific attention because it changes the dynamics of opportunity:

Technology does not cause infidelity, but it removes friction. A person who might never approach someone at a bar can send a private message at 2 AM with zero social consequence. The barrier between thought and action is lower than it has ever been.

This is particularly relevant for emotional affairs. A 2024 study on social media addiction and infidelity-related behaviors (published in SAGE Journals) found that heavy social media use correlated with higher rates of infidelity-related behaviors, though the relationship was moderated by relationship satisfaction. In other words, technology is most dangerous in already-vulnerable relationships.

What Does Not Predict Cheating

The data also reveals factors that do not reliably predict infidelity:

The strongest protective factors are relationship satisfaction, emotional connection, and commitment level. Everything else is secondary.


How Affairs Start: Workplace, Social Media, and Dating Apps

Knowing where affairs begin helps you understand the patterns.

The Workplace

The office remains the most common breeding ground for affairs:

Proximity, shared stress, and daily interaction create an environment where emotional boundaries erode gradually. Most workplace affairs begin as "just friendship" before crossing a line.

Social Media and Messaging

Digital platforms have fundamentally changed how affairs begin and continue:

If you are wondering about specific platforms, our breakdown of apps cheaters use covers which platforms carry the highest risk.

Dating Apps

Dating apps create a particularly direct path to infidelity:

For a deeper analysis of dating platform infidelity, our full dating app cheating statistics article breaks down usage patterns across 15+ platforms.

If you want to check if your partner is on dating sites, a targeted search can give you a definitive answer within minutes.

How Affairs Get Discovered: Detection Methods and Accuracy

Most people do not hire a private investigator. The data on how affairs actually come to light is revealing.

Primary Discovery Methods

A landmark study of 94,943 individuals published in Psychology Today (2024) found:

How the Affair Was DiscoveredPercentage
Cheater confessed on their own56.8%
Caught by partner21.5%
Confessed when confronted8.3%
Accidentally discovered8.0%
Third party informed the partner4.5%

The most significant finding: more than half of cheaters eventually confess without being caught. This suggests that guilt and the psychological burden of maintaining a secret play a larger role in exposure than surveillance or snooping.

Technology-Based Detection

Among those who were actively caught (rather than confessed to), technology plays a dominant role:

Partner Intuition

The accuracy of gut feelings is backed by data:

If you have a persistent gut feeling he's cheating but lack proof, the statistics suggest that feeling is worth investigating. That does not mean every anxious thought equals infidelity, but a strong and consistent intuition is right far more often than it is wrong.

The Average Timeline

Affairs do not get discovered quickly. Research from IllicitEncounters.com found that it takes an average of 4 years for infidelity to be exposed. Additionally, 63% of cheaters say they have been caught at some point in their lives, meaning roughly 37% may never face discovery.

If you think your boyfriend is cheating but have no proof, you are not alone. The gap between suspicion and confirmation is one of the most stressful experiences people report in relationships.


Serial Cheating and Repeat Infidelity

"Once a cheater, always a cheater" is one of the most repeated phrases in relationship advice. The research provides a clear but nuanced answer.

The 3x Rule

A study from the University of Denver, published in the Archives of Sexual Behavior, tracked individuals across multiple relationships and found that people who cheated in one relationship had 3 times the odds of cheating in the next, compared to those who had not been unfaithful.

But It Is Not Absolute

The same study found important caveats:

The research lead, Dr. Kayla Knopp, noted that while past infidelity is an important risk factor, it is not a certainty. Change is possible, particularly with professional help and self-awareness.

Patterns of Suspicion

An equally interesting finding: people whose partners cheated on them were twice as likely to be cheated on again in their next relationship. This suggests that attraction patterns and relationship dynamics play a role alongside individual cheating behavior.

Relationship Outcomes After Cheating

What happens after an affair is discovered? The data paints a complex picture.

Immediate Response: Most Couples Stay

Despite the common assumption that cheating automatically ends relationships:

Divorce and Separation Rates

The American Psychological Association reports that 20% to 40% of divorces are directly linked to infidelity. Among people who have cheated:

Compare this to the faithful population:

The difference is stark: cheating roughly doubles the odds of eventual divorce.

Therapy and Reconciliation

Professional help significantly changes outcomes:

True Recovery Is Rare

Here is the number that puts everything in perspective: only 15% to 20% of couples achieve meaningful reconciliation (restored trust, emotional healing, and relationship satisfaction) five years after discovery.

Staying together is common. Truly recovering is not.

The Forgiveness Factor

Forgiveness is the single strongest predictor of long-term relationship stability after infidelity. Research shows that 80% of partners who genuinely forgive remain married after five years. The critical word is "genuinely." Forced or premature forgiveness does not produce the same outcomes.

Impact on Children and Family

Infidelity does not happen in a vacuum. When children are involved, the data shows ripple effects that extend for years:

The financial fallout compounds these effects. The average divorce costs $7,000 to $15,000 in legal fees alone, not including the ongoing expense of maintaining separate households. Infidelity-driven divorces tend to be more adversarial and therefore more expensive than divorces caused by other factors.

These statistics are not meant to pressure anyone into staying in a destructive relationship. They are context for understanding the full scope of what infidelity puts at stake.

If you have discovered infidelity and are deciding next steps, knowing what to do if your partner is on a dating app can help you make informed decisions rather than reactive ones.


The Mental Health Impact of Infidelity

Cheating is not just a relationship problem. It is a mental health event for the betrayed partner.

PTSD-Level Symptoms

Research from Psych Central and multiple clinical studies found that 30% to 60% of betrayed partners experience symptoms that meet clinical thresholds for post-traumatic stress disorder. These symptoms include:

Some research found that infidelity-related PTSD symptoms were more severe than symptoms caused by physical injury or perceived life threats. This finding challenges the common dismissal of cheating as "just a relationship issue."

Depression Risk

A study published in Family Process found that people who discovered a partner affair had 9 times the odds of meeting criteria for a major depressive episode compared to those who did not experience partner infidelity.

55% of spouses whose partner cheated report chronic anxiety or depression that persists long after the affair ends.

How Discovery Method Affects Outcomes

The way someone learns about an affair significantly affects their mental health outcome. Research consistently shows that being told directly by the cheating partner produces better psychological outcomes than discovering the affair through indirect methods (finding texts, hearing from a third party, or catching them in person).

This is one reason why the 56.8% confession rate matters. When cheaters confess voluntarily, their partners tend to experience less severe psychological harm than when the truth emerges through surveillance or accident.

Long-Term Effects

Infidelity can produce lasting changes in how people approach relationships:

These effects are not limited to the betrayed partner. 60% of cheaters report significant guilt or shame within three months of the affair, and 85% of children in divorced families affected by parental infidelity report long-term trust issues.


Global Cheating Statistics: How the U.S. Compares

Infidelity rates vary dramatically across countries, shaped by cultural norms, gender equality, and social attitudes.

Highest Infidelity Rates by Country

World Population Review tracks global data:

CountryEstimated Infidelity Rate
Thailand51%
Denmark46%
Italy45%
Germany45%
France43%
Norway41%
Belgium40%
United States39-40%
Spain39%
United Kingdom36%

Lowest Infidelity Rates

Cultural Context

Thailand's high rate is partly attributed to the cultural tradition of "mia noi" (minor wife), which has historically normalized extramarital relationships, particularly for men.

Nordic countries show an interesting pattern: despite high overall rates, the gender gap is much smaller than in other regions. Men and women cheat at similar rates in Denmark, Norway, and Sweden, consistent with these countries' high gender equality scores.

The U.S. rate of approximately 39-40% in global surveys is notably higher than the GSS figure of 16% (men and women combined). This discrepancy reflects different survey methodologies: global surveys tend to use broader definitions of infidelity and wider time frames.


Dating Apps and Infidelity: The Digital Factor

Digital platforms have not necessarily increased overall infidelity rates, but they have changed how affairs begin, how they are maintained, and how they are discovered.

The Access Problem

The core issue with dating apps and infidelity is access:

Research from Computers in Human Behavior found that dating app success was indirectly associated with intention to cheat, and that self-perceived desirability on the apps positively predicted users' intention to be unfaithful.

How Many Committed People Are on Dating Apps?

The numbers are significant:

These numbers explain why searches like "find out if your partner is on dating apps" are among the most common relationship queries online. The concern is not unfounded.

Defining the Line

What constitutes cheating on dating apps is not universally agreed upon:

The gray area between "just looking" and active infidelity is where many relationship conflicts begin. A dating profile search by name can remove the ambiguity entirely by showing you whether an active profile exists.


Financial Infidelity: The Other Kind of Cheating

Not all infidelity is sexual or emotional. Financial infidelity — hiding spending, secret accounts, or lying about money — affects a staggering number of relationships.

How Common Is Financial Infidelity?

Bankrate research found that 40% of people in committed relationships have committed financial infidelity against their current partner. Among U.S. adults who have ever combined finances with a partner, 43% have committed at least one financial deception.

The most common forms:

Type of Financial SecretPercentage
Spending more than partner would accept33%
Hiding debt from partner23%
Secret credit card17%
Secret savings account15%

Men are twice as likely as women to hide major purchases, and 1 in 5 men admit to secretly spending over $1,000 without their partner's knowledge.

Generational Patterns

Financial infidelity skews younger. 67% of Gen Z adults (ages 18-28) in committed relationships have either experienced or carried out financial deception. This tracks with the generational pattern of lower marriage rates but higher cohabitation rates, where financial boundaries may be less clearly defined.

The Overlap with Sexual Infidelity

Nearly half of Americans (45%) believe keeping financial secrets is as damaging as physical infidelity (Bankrate, 2024). Research from ScienceDirect confirms this perception has merit: couples where one partner commits financial infidelity report lower relationship satisfaction and accumulate fewer total assets over time.

Financial secrecy often accompanies other forms of cheating. Credit card statements revealing unfamiliar charges catch 16.3% of cheating men and 8.8% of cheating women. Hidden spending on gifts, hotels, and dinners for an affair partner creates a paper trail that many cheaters fail to cover.


Infidelity in Long-Distance and Military Relationships

Certain relationship structures face unique infidelity pressures. The data on long-distance and military couples reveals both expected and surprising patterns.

Long-Distance Relationships

Contrary to popular belief, long-distance relationships do not have dramatically higher physical cheating rates:

An unexpected finding from geographic research: couples who live roughly 100 miles apart face the highest cheating risk. Those in the same city and those separated by very long distances (cross-country) actually cheat at lower rates. The middle zone — close enough for occasional visits but far enough for significant alone time — creates the most vulnerability.

Frequency of in-person contact also matters. Among long-distance couples who met monthly, 68% were certain no cheating had occurred. That confidence dropped to 48% for couples who only met every 4-6 months.

Military Relationships

Military couples face elevated infidelity rates driven by deployment-related separation and stress:

These numbers reflect both the strain of extended separation and the unique stressors of military life. One positive finding: military couples are far more likely to seek professional help. Approximately 50-60% of active duty couples pursue therapy to address infidelity, compared to roughly 15% of civilian couples.

If you are in a long-distance or military relationship and concerned about your partner's online activity, you can find out if your partner is on dating apps regardless of your physical location. Digital searches work the same whether you are across town or deployed overseas.


Common Misconceptions About Cheating

The data contradicts several widely held beliefs about infidelity.

Misconception 1: "Cheaters Are Always Unhappy in Their Relationships"

Reality: 27% of cheaters cited opportunity as their primary trigger, not dissatisfaction. Many cheaters report being relatively satisfied with their primary relationship. Infidelity is not always an escape from a bad relationship. Sometimes it is a failure of boundaries in an otherwise functional one.

Misconception 2: "Men Cheat Way More Than Women"

Reality: While men do cheat more overall (20% vs. 13%), the gap is smaller than most people assume. Among young adults 18-29, women actually cheat at slightly higher rates. The gender gap has been narrowing for two decades.

Misconception 3: "Once a Cheater, Always a Cheater"

Reality: People who cheat once have 3x the odds of cheating again, which is significant. But the majority of people who cheated in one relationship did not cheat in their next relationship during the study period. About 75-78% of people who cheat once do not repeat it in their next relationship.

Misconception 4: "You Would Know If Your Partner Was Cheating"

Reality: It takes an average of 4 years for affairs to be discovered. 37% of cheaters report never being caught. And 56.8% of affairs only come to light because the cheater eventually confesses, not because the partner detected it. If you are wondering whether you are am I paranoid or is he cheating, that question itself deserves honest examination.

Misconception 5: "Infidelity Is an Epidemic Getting Worse Every Year"

Reality: GSS data shows infidelity rates have been relatively stable for decades. Male infidelity has actually declined. The perception of an epidemic is driven by greater social media visibility and more open discussion, not by actual increases in cheating behavior.

Misconception 6: "Education and Income Protect Against Cheating"

Reality: Education level shows almost no correlation with infidelity rates (15-18% across all education levels). Higher income is associated with slightly higher infidelity rates for men, likely because it creates more opportunity and social power.


How to Use These Statistics

Numbers are useful only if they lead to action. Here is how to apply this data to your situation.

If You Suspect a Partner Is Cheating

The research says your instincts are worth trusting, particularly if you are a woman (85% accuracy rate for female suspicions). But instinct alone is not confirmation. Before making life-altering decisions:

  1. Document specific behavioral changes rather than relying on feelings alone. Look for the signs your partner is cheating that research has validated.
  2. Check the digital footprint. With 38% of affairs starting through social media and 18-42% of dating app users being in relationships, checking for active profiles is rational, not paranoid.
  3. Understand the base rates. If your partner is a married man in his 50s, the background infidelity rate for his demographic is 28%. If your partner is a married woman under 30, the rate is 11%. Context matters. You can also take our is my partner cheating quiz to evaluate your specific situation against the data.
  4. Know that confession is the most common discovery method. If you confront your partner with specific concerns (not vague accusations), there is a reasonable chance of an honest conversation. Over half of cheaters eventually confess without being caught.

If You Have Confirmed Infidelity

The data on outcomes is clear:

These numbers are not meant to tell you what to do. They are meant to give you realistic expectations for whichever path you choose.

Frequently Asked Questions

According to the General Social Survey, 20% of married men and 13% of married women admit to sexual infidelity during their marriage. A YouGov poll found that roughly one in three Americans report having cheated on a partner at some point. Rates are higher when emotional affairs are included.

Men cheat at higher overall rates (20% vs. 13%), but the gap depends on age. Women ages 18 to 29 actually cheat at slightly higher rates than men in the same age group (11% vs. 10%), according to the General Social Survey. The gender gap widens significantly in older age groups.

Emotional dissatisfaction is the top reason for women (70%), while sexual dissatisfaction drives about 50% of male infidelity. Other common factors include boredom (50% of long-term marriages), feeling unappreciated, low commitment, and pure opportunity, which 27% of cheaters cite as their main trigger.

Research from a study of nearly 95,000 people found that 56.8% of cheaters confessed on their own, 21.5% were caught by their partner, 8.3% confessed when confronted, and 8% were accidentally discovered. Phone and text monitoring catches 40% of millennial cheaters specifically.

Between 60% and 75% of couples stay together immediately after discovering an affair. Couples who pursue therapy have a 70% to 74% reconciliation rate. But meaningful recovery with restored trust is rarer. Only 15% to 20% of couples achieve full reconciliation five years after discovery. Tools like CheatScanX can help verify whether a partner has truly left dating platforms behind.
