A clear collection of national figures about trauma exposure, PTSD, mental health, and care. Every number is linked to its original public source and marked with the year of the underlying data.

At a glance
These figures describe national surveys and studies, not any one person’s experience. They are here to make reliable information easier to find and cite.
17.3%
of U.S. adults reported four or more adverse childhood experiences.
This is the same national 2011 to 2020 CDC survey analysis. The figure is a weighted estimate, not a count of every individual in the country.
3.6%
of U.S. adults had PTSD in the past year in the National Comorbidity Survey Replication.
The underlying survey was conducted in 2001 through 2003. It remains the prevalence estimate presented by the National Institute of Mental Health, and its age should be considered when it is cited.
22.8%
of U.S. adults had any mental illness in the past year in 2023.
SAMHSA estimates this as 58.7 million adults. In this survey, the measure includes diagnosable mental, behavioral, or emotional disorders and excludes developmental disorders and substance use disorders.
23.9%
of U.S. adults received mental health treatment in the previous 12 months in 2023.
The CDC measure includes medication for mental health as well as therapy with a mental health professional. It increased from 19.2% in 2019.
