About 7% of U.S. veterans will have PTSD at some point in their lives, based on national survey data. At any given time, the number with active symptoms is lower, around 5%. But those broad figures mask significant variation depending on gender, service era, and whether someone is actively using VA health care.
Lifetime vs. Current Rates
The distinction between “ever had PTSD” and “has PTSD right now” matters. The 7% lifetime figure comes from a nationally representative survey of over 3,100 veterans conducted in 2012-2013. A more recent survey of over 4,000 veterans in 2019-2020 found that 5% had PTSD in the past month.
Among veterans who actually use VA health care, the numbers are considerably higher. Of the 5.8 million veterans served by the VA in fiscal year 2024, roughly 14% of men and 24% of women carried a PTSD diagnosis. That gap between the general veteran population (5-7%) and VA patients (14-24%) likely reflects the fact that veterans dealing with mental health conditions are more likely to seek VA services in the first place.
Women Veterans Face Higher Rates
PTSD affects women veterans at roughly double the rate of men. The 2019-2020 national survey found past-month PTSD in 11% of women veterans compared to 4% of men. Military sexual trauma is a major driver of that gap.
A study of 325 female veterans found that 35% met the threshold for a probable PTSD diagnosis. Among those women, 76% reported experiencing sexual assault during their military service. Women who experience sexual trauma in the military are four to nine times more likely to develop PTSD than female veterans without that history. The rates were especially high among post-9/11 female veterans who reported military sexual assault: 65% of them met the clinical cutoff for probable PTSD, compared to 53% of pre-9/11 female veterans with similar experiences.
How Veteran Rates Compare to Civilians
The general U.S. population has a lifetime PTSD prevalence of about 6%, making the veteran rate of 7% only slightly higher at first glance. But that comparison is misleading. Veterans are predominantly male, and men in the general population develop PTSD at lower rates than women. When you compare male veterans to male civilians, the difference is more pronounced. The nature of the trauma also differs: combat exposure, repeated deployments, and military sexual trauma create a distinct risk profile that civilian statistics don’t capture.
Substance Use and PTSD Often Overlap
PTSD rarely shows up alone. Among Iraq and Afghanistan veterans with a lifetime PTSD diagnosis, about 34% of men also had an alcohol use disorder, and 17% had another substance use disorder. For women, the rates were 20% for alcohol and roughly 11% for other substances. This overlap complicates recovery because each condition can reinforce the other: drinking or drug use may temporarily numb PTSD symptoms but ultimately prevents processing of the trauma.
Most Veterans Report Barriers to Treatment
Even among veterans who make it to a PTSD specialty clinic and start treatment, nearly half (47%) drop out before completing it. The reasons are telling. About 85% of veterans in treatment reported at least one barrier, and the most common ones weren’t logistical. Nearly half cited difficulty interacting with other people, 39% had trouble being in public, and 36% pointed to work conflicts. These are, in many cases, symptoms of PTSD itself creating obstacles to the treatment designed to address it.
Financial strain, institutional hurdles like wait times and paperwork, and stigma around mental health care also play a role. The result is a treatment gap where many veterans with PTSD either never start evidence-based therapy or leave before it has a chance to work.
Why the Numbers Vary So Widely
You’ll see PTSD prevalence figures for veterans ranging from 5% to over 20% depending on the source, and all of them can be technically accurate. The variation comes down to three things: who was surveyed (all veterans or just VA patients), what time frame was measured (lifetime or current symptoms), and which diagnostic standard was used.
When the diagnostic criteria for PTSD were updated in 2013, the change had minimal effect on prevalence numbers, shifting them downward by only about 1%. The bigger factor is the population being studied. A survey of all living veterans will always produce a lower number than a study of veterans seeking mental health care at the VA. Neither is wrong, but they answer different questions. The 5-7% range reflects how common PTSD is across the entire veteran population. The 14-24% range among VA patients reflects the reality for veterans actively engaged with the health care system.
