PTSD Statistics: Recent Data and Insights

Post-traumatic stress disorder touches far more people than most realize. The PTSD statistics in this guide show that roughly 1 in 15 U.S. adults will develop the condition at some point, and that certain groups, from combat veterans to sexual assault survivors to firefighters, carry a much heavier load. Trauma itself is close to universal: about 7 in 10 people worldwide live through at least one traumatic event.

We pulled every figure that follows from primary sources only: the National Institute of Mental Health, the U.S. Department of Veterans Affairs and its National Center for PTSD, the Centers for Disease Control and Prevention, the World Health Organization’s World Mental Health Surveys, and peer-reviewed journals. 

Each statistic links back to its original source, so you can verify it. The aim is a clear, current picture of how common PTSD is, who it affects most, what it co-occurs with, and how well treatment works.

Behind every number is a person. The encouraging part of the data is that PTSD is treatable, and the people who get evidence-based care recover at far higher rates than those who wait it out alone.

Discover the most interesting facts about PTSD

When it comes to PTSD, interesting facts cut against common assumptions. PTSD isn’t just a condition affecting veterans. Most cases in the United States trace back to events like sexual violence, serious accidents, and the sudden loss of a loved one. 

The single largest driver of PTSD risk worldwide is interpersonal violence, especially sexual assault, not combat.

The prevalence of PTSD is also strongly shaped by sex and exposure. Women experience PTSD at roughly twice the rate of men, largely because they’re more likely to survive the kinds of trauma that carry the highest risk. 

And while trauma is widespread, PTSD isn’t inevitable after it. Most people who live through a traumatic event do not develop the disorder, which is part of why understanding the prevalence of PTSD matters for spotting who needs help.

Here are some quick PTSD stats that frame the rest of this guide:

• About 6.8% of U.S. adults will have PTSD in their lifetime, and about 3.6% in any given year. (NIMH)
• Around 70% of people worldwide experience at least one traumatic event, yet only a minority develop PTSD. (WHO World Mental Health Surveys)
• Women are about twice as likely as men to develop PTSD. (VA National Center for PTSD)
• With trauma-focused therapy, more than half of patients no longer meet the criteria for PTSD. (VA Research)

28 top PTSD statistics and facts

The statistics of PTSD below are organized into three groups: general prevalence and demographics, PTSD in high-exposure populations, and the impact, comorbidities, and treatment outcomes that follow a diagnosis. 

Together, they offer a complete view of the statistics for PTSD as the research stands today.

General prevalence and demographics

This section covers the core PTSD prevalence figures: how many people have the condition, how rates differ by sex, age, and race, and how the numbers compare across the world. 

Most U.S. figures come from the National Comorbidity Survey datasets maintained by the National Institute of Mental Health.

Lifetime and past-year PTSD prevalence in U.S. adults

An estimated 6.8% of U.S. adults will experience PTSD at some point in their lives, and 3.6% have it in any given year.

That lifetime figure means roughly 1 in 15 American adults. The past-year rate translates to about 1 in 25 adults living with PTSD right now. These remain the most widely cited prevalence of PTSD in the US figures from federal data.

Gender differences in PTSD rates

Women experience PTSD at roughly twice the rate of men: about 8% of women versus 4% of men over a lifetime.

Past-year data show the same gap, at 5.2% for women compared with 1.8% for men. The difference is driven largely by exposure: women are more likely to survive sexual violence, which carries one of the highest risks of any trauma type.

Source: U.S. Department of Veterans Affairs, National Center for PTSD

PTSD prevalence worldwide

Across 24 countries, the lifetime prevalence of PTSD is 3.9% in the general population and 5.6% among people who have been exposed to traumatic events.

These PTSD statistics worldwide come from the WHO World Mental Health Surveys, the largest coordinated cross-national study of mental disorders. 

Rates run higher in high-income countries (about 5.0%) than in upper-middle (2.3%) and lower-income countries (2.1%), a pattern researchers attribute partly to differences in reporting and diagnosis.

Global trauma exposure

About 70% of people worldwide, roughly 7 in 10, will live through at least one traumatic event, averaging more than three traumas per person.

Despite this near-universal exposure, only a minority go on to develop PTSD. Globally, an estimated 13 million people develop the disorder each year. 

The gap between trauma exposure and PTSD onset is one of the most important PTSD data points for understanding resilience.

PTSD by age group

Past-year PTSD peaks in midlife: 5.3% of adults aged 45 to 59 have it, compared with 4.0% of those 18 to 29, 3.5% of those 30 to 44, and just 1.0% of adults 60 and older.

The midlife peak may reflect accumulated trauma exposure over time, while the sharp drop after 60 may reflect both symptom remission and underreporting in older adults.

Source: National Institute of Mental Health (NIMH)

PTSD severity and impairment

Among U.S. adults with past-year PTSD, 36.6% have serious impairment, 33.1% moderate, and 30.2% mild.

In other words, more than one in three people with PTSD experience symptoms severe enough to significantly disrupt work, relationships, and daily functioning. PTSD is rarely a minor condition for those who have it.

Source: National Institute of Mental Health (NIMH)

PTSD in adolescents

An estimated 5.0% of U.S. adolescents aged 13 to 18 have had PTSD, with girls affected far more often (8.0%) than boys (2.3%).

The sex gap that appears in adulthood is already visible in the teen years. About 1.5% of adolescents experience severe impairment from PTSD symptoms.

Source: National Institute of Mental Health (NIMH)

PTSD prevalence by race and ethnicity

Lifetime PTSD prevalence is highest among Black adults (8.7%), intermediate among White (7.4%) and Hispanic adults (7.0%), and lowest among Asian adults (4.0%).

The same national study found that minority groups were significantly less likely to seek treatment, with fewer than half of affected minority adults pursuing care. 

Higher risk among Black adults persisted even after accounting for differences in trauma exposure.

How common trauma is versus how common PTSD is

More than half of all U.S. adults will experience at least one traumatic event, but most never develop PTSD.

This is one of the most reassuring statistics on PTSD: trauma is common, yet the human capacity for recovery is the norm. 

Strong social support after a traumatic event measurably lowers the risk of developing PTSD.

The economic scale of PTSD

The PTSD cost to the United States is an estimated $232.2 billion in a single year (2018), exceeding the burden of anxiety or depression. That total spans health care, disability, unemployment, and lost productivity. 

The per-person annual cost was about $18,640 for civilians and $25,684 in the military population, a reminder that the prevalence of PTSD carries a heavy societal price tag.

Source: Davis et al., Journal of Clinical Psychiatry (2022)

Key takeaways: general prevalence About 6.8% of U.S. adults have PTSD in their lifetime, and 3.6% in any given year. Women are affected roughly twice as often as men, a gap that appears as early as adolescence. Worldwide lifetime prevalence is 3.9%, rising to 5.6% among the trauma-exposed. Around 70% of people experience trauma, but most never develop PTSD. PTSD costs the U.S. more than $232 billion a year, more than anxiety or depression.

PTSD in high-exposure populations

Some groups face traumatic events as a routine part of their lives or survive trauma types that carry an especially high PTSD risk. 

The veteran PTSD statistics, first responder PTSD statistics, and sexual assault figures below show how sharply rates climb with exposure.

PTSD rates among U.S. military veterans

About 7 in 100 veterans (7%) will have PTSD at some point in their lives, slightly higher than the 6% rate among civilians.

These veteran PTSD statistics from the National Center for PTSD understate the burden for those who saw combat. 

Among veterans who use VA health care, lifetime rates are far higher, reflecting the concentration of more severe cases in that system.

Source: U.S. Department of Veterans Affairs, National Center for PTSD

Gender differences among veterans

Female veterans have a lifetime PTSD prevalence near 13%, roughly double the 6% rate among male veterans.

The leading driver is military sexual trauma. These PTSD in veterans statistics mirror the civilian pattern, where women carry higher rates, but the gap is wider in the military because of elevated exposure to assault and harassment.

Source: National Health and Resilience in Veterans Study, via VA National Center for PTSD

PTSD by military service era

Lifetime PTSD reaches about 29% among Iraq and Afghanistan (OIF/OEF) veterans, compared with roughly 30% for Vietnam veterans, 12% for Gulf War veterans, and about 3% for World War II and Korea veterans.

In a given year, 11% to 20% of OIF/OEF veterans have PTSD. The variation by era reflects differences in combat intensity, deployment length, and how trauma was recognized at the time.

Source: U.S. Department of Veterans Affairs

Military sexual trauma

About 1 in 3 women veterans and 1 in 50 men report military sexual trauma when screened by their VA provider.

Military sexual trauma, which covers sexual assault and harassment during service, is strongly linked to PTSD and helps explain the high rates among female veterans. The figures likely undercount men, who tend to report at lower rates.

Source: U.S. Department of Veterans Affairs, National Center for PTSD

PTSD among first responders

A 2025 meta-analysis of 138 studies found a pooled PTSD prevalence of 14.3% among first responders with routine trauma exposure, more than twice the general population rate.

First responder PTSD statistics were lower (8.3%) among responders studied after large-scale disasters than among those facing routine daily exposure, and the analysis found prevalence rising over time. Over 80% of first responders report experiencing traumatic events on the job.

Source: Systematic review and meta-analysis, Clinical Psychology Review (2025)

PTSD among firefighters and paramedics

Paramedics show a PTSD prevalence of about 11%, while firefighter PTSD statistics range widely across studies, from 6.4% up to 57%.

Police officers fall between roughly 5.8% and 19.6%. The wide ranges reflect different measurement tools and exposure levels, but every estimate sits well above the civilian baseline. 

Repeated exposure, not a single event, drives much of the risk in these roles.

Source: Petrie et al., systematic review, PLOS One (2022)

PTSD after sexual assault

About 45% of women who experience rape develop PTSD, and the rate is even higher among men who are raped, at roughly 65%.

In the same national research, sexual assault was more likely to lead to PTSD than almost any other trauma type, including combat. 

Close to half of all PTSD cases in the U.S. trace back to physical or sexual violence.

Source: National Center for PTSD, drawing on the National Comorbidity Survey

How PTSD symptoms unfold after sexual assault

A meta-analysis found that 81% of sexual assault survivors had significant PTSD symptoms one week later, 75% met full criteria at one month, 54% at three months, and 41% at one year.

The figures show both the severity of early trauma response and the reality that, for many survivors, symptoms persist well beyond the first months without treatment. Early support matters.

PTSD and intimate partner violence

About 1 in 4 women and 1 in 10 men experience physical violence, rape, or stalking by an intimate partner that results in impacts such as injury or post-traumatic stress symptoms.

PTSD is one of the most common consequences of intimate partner violence and can persist for years after the abuse ends. National survey data place this among the most prevalent sources of trauma in the country.

Source: CDC National Intimate Partner and Sexual Violence Survey (NISVS)

Which traumas carry the highest PTSD risk

Interpersonal violence carries the highest PTSD risk of any trauma type, and intimate partner sexual violence alone accounts for nearly 43% of all person-years lived with PTSD worldwide.

Rape, other sexual assault, and being stalked produce the highest conditional risk of PTSD, even though they’re less common than events like accidents. 

This is why trauma type, not just trauma frequency, shapes the global PTSD picture.

Source: WHO World Mental Health Surveys, European Journal of Psychotraumatology

Key takeaways: high-exposure populations About 7% of veterans have PTSD over their lifetime, rising to 29% for Iraq and Afghanistan veterans. Female veterans are affected at roughly double the rate of male veterans, largely due to military sexual trauma. First responders show a pooled PTSD prevalence of 14.3%, more than twice the general population. Around 45% of women who are raped develop PTSD, and sexual violence underlies close to half of all U.S. cases. Interpersonal violence is the single highest-risk trauma category worldwide.

PTSD impact, comorbidities, and treatment outcomes

PTSD rarely travels alone. The figures below cover PTSD comorbidity with other mental health conditions, the link to suicide risk, the gap between who needs care and who gets it, and how effective treatment is when people do receive it.

PTSD co-occurrence with substance use

Roughly 30% to 60% of people with PTSD also have a co-occurring alcohol or drug use disorder.

Lifetime substance use disorder runs from 21.6% to 43.0% in people with PTSD, compared with 8.1% to 24.7% in those without. 

Many people use substances to cope with intrusive symptoms, which complicates recovery and points to the value of integrated treatment.

Source: American Journal of Psychiatry literature review

PTSD co-occurrence with depression and anxiety

PTSD is highly comorbid with mood and anxiety disorders: among women with PTSD, depression and other anxiety disorders are the most common co-occurring conditions, while among men, alcohol use disorder ranks first, followed by depression.

This clustering matters because comorbid depression and anxiety raise the risk of suicidal thoughts and make PTSD harder to treat if the conditions are addressed in isolation rather than together.

Source: American Journal of Psychiatry literature review

PTSD and suicide risk

In a national registry study, the odds of death by suicide were 5.3 times higher among people diagnosed with PTSD, even after adjusting for other psychiatric and demographic factors.

A separate cohort of 3.1 million people found suicide rates about 6.7 times higher in women and 4.0 times higher in men with PTSD. The strong link is one reason routine screening and early treatment are central to suicide prevention.

The PTSD treatment gap and access to care

Only about half of people with PTSD access any care, and even fewer are treated by a mental health professional.

Without treatment, recovery can take a long time: research has estimated a median of well over a decade from onset to remission for untreated PTSD. 

Cost, limited access to specialized providers, and stigma are the most cited barriers. 

The takeaway is that the treatment gap, not the absence of effective treatment, is the core problem.

Source: Davis et al., Journal of Clinical Psychiatry (2022)

How often PTSD resolves without treatment

Among people who recover without specific treatment, about 20% improve within 3 months, 27% within 6 months, 50% within 24 months, and 77% within 10 years.

These figures from the WHO World Mental Health Surveys show that some natural recovery does happen, but slowly, and a substantial minority stays symptomatic for years. That long tail is exactly what evidence-based treatment shortens.

Source: Morina et al., WHO World Mental Health Surveys (recovery analysis)

Evidence-based therapy outcomes and recovery rates

About 53 of every 100 patients who complete trauma-focused therapy (CPT, prolonged exposure, or EMDR) no longer have PTSD afterward, and 42 of 100 reach remission with medication alone.

Across cognitive behavioral therapy trials, remission rates of 53% to 63% are common. The headline statistics for PTSD treatment are genuinely hopeful: the people who receive evidence-based care recover at far higher rates than those who wait.

PTSD and divorce rates

Mental health conditions raise the odds of divorce across the board, and the National Vietnam Veterans Readjustment Study found that about 60% of male veterans with PTSD had been divorced, compared with roughly 35% of those without it.

A multinational study found that all 18 mental disorders examined were associated with higher divorce odds, ranging from 1.2 to 1.8 times. 

PTSD divorce rates reflect the strain that symptoms like emotional numbing, avoidance, and hyperarousal place on close relationships.

Source: Multinational WHO study on mental disorders, marriage and divorce

PTSD disability and lost productivity

Unemployment and lost productivity make up about 35% of the excess economic burden of PTSD, and once disability costs are added, the share approaches half.

These PTSD disability rates underscore that PTSD is a leading cause of functional impairment, not only emotional distress. 

Evidence-based treatment and supported employment can return many people to steady, higher-paying work.

Source: Davis et al., Journal of Clinical Psychiatry (2022)

Key takeaways: impact and treatment Between 30% and 60% of people with PTSD also have a substance use disorder. Odds of death by suicide are several times higher among people with PTSD. Only about half of people with PTSD ever access care, despite effective treatments existing. More than half of patients who complete trauma-focused therapy no longer meet PTSD criteria. PTSD is a major driver of disability, unemployment, and lost productivity.

Get the PTSD help you need

The clearest message in all of these PTSD statistics is that the condition is both common and highly treatable, yet most people who have it never get care. That gap is where help makes the biggest difference. 

If trauma is affecting your sleep, your relationships, your work, or your sense of safety, you don’t have to wait years for it to fade on its own.

If you’re not sure whether what you’re experiencing is PTSD, a quick, private screening is a good first step.  You can take a confidential PTSD test to check your symptoms.

FAQs

What percentage of Americans have PTSD?

About 6.8% of U.S. adults will have PTSD at some point in their lives, and an estimated 3.6% have it in any given year, according to the National Institute of Mental Health. 

That works out to roughly 1 in 15 adults over a lifetime and about 1 in 25 in a given year.

Is PTSD more common in men or women?

PTSD is significantly more common in women. About 8% of women will develop PTSD in their lifetime compared with around 4% of men, roughly double the rate, per the National Center for PTSD. 

The gap largely reflects women’s higher exposure to sexual violence, which carries an especially high PTSD risk.

What percentage of veterans have PTSD?

About 7% of veterans will experience PTSD at some point in their lives, slightly above the 6% civilian rate, according to the U.S. Department of Veterans Affairs. 

The number climbs sharply by service era, reaching roughly 29% lifetime among Iraq and Afghanistan veterans.

Do statistics about PTSD show that it can be cured?

Yes, the data show PTSD is highly treatable. About 53 of every 100 people who complete trauma-focused therapy no longer meet the criteria for PTSD, and cognitive behavioral therapy produces remission in 53% to 63% of adults. 

Clinicians often speak of recovery or remission rather than a permanent cure.

What is the PTSD suicide rate?

PTSD sharply raises suicide risk. A national registry study found the odds of death by suicide were about 5.3 times higher among people with PTSD, and a large cohort found suicide rates several times higher than in people without the disorder. 

This is why early screening and treatment are so important.

How does PTSD affect divorce rates?

PTSD is associated with higher divorce rates. The National Vietnam Veterans Readjustment Study found that about 60% of male veterans with PTSD had been divorced versus roughly 35% without it, and broader research links every studied mental disorder to higher divorce odds. 

Symptoms like avoidance and emotional numbing strain relationships.

What country has the highest PTSD rates?

Among countries in the WHO World Mental Health Surveys, higher-income nations tend to report higher PTSD prevalence, with Northern Ireland among the highest at about 8.8% lifetime. 

Conflict-affected populations show far higher rates, with some war-survivor studies reporting point prevalence above 25%.
