How Many Young Adults Struggle With Mental Health?

If it feels like more young adults are struggling with their mental health than ever before, the data backs that up. Emerging adulthood — roughly ages 18 to 25 — consistently shows the highest rates of mental illness of any adult age group in the U.S. Understanding just how common these struggles are can help take away some of the isolation and shame that often keeps young adults from getting help.

The Numbers Behind the Struggle

According to SAMHSA’s 2024 National Survey on Drug Use and Health, roughly 32% of young adults ages 18–25 experienced a mental illness in the past year — more than 11.6 million people. That’s a notably higher rate than adults 26 and older.

A few specific findings stand out:

  • Depression hits young adults hardest. Nearly 16% of young adults ages 18–25 experienced a major depressive episode in the past year — close to double the rate seen in older adults.
  • Anxiety follows a similar pattern. About 14.5% of young adults reported moderate or severe symptoms of generalized anxiety, compared to 9% of adults ages 26–49 and under 4% of adults 50 and older.
  • Treatment gaps remain wide. Even though young adults report the highest rates of mental illness, roughly half of those affected received any treatment in the past year — meaning a substantial number are managing these struggles without support.

Why Young Adulthood Is Such a High-Risk Period

The years between 18 and 28 bring a lot of change at once: leaving home, starting college or a career, forming new relationships, and figuring out identity and independence — often without the built-in structure of high school or a family household. That combination of transition and uncertainty can intensify existing mental health challenges or bring on new ones, from anxiety and depression to ADHD symptoms that become harder to manage without structure.

The Treatment Gap Is a Solvable Problem

The gap between how many young adults struggle and how many get help isn’t about a lack of effective treatment — it’s about access, stigma, and not knowing where to start. Specialized, age-appropriate care exists, and it works. Confluence Behavioral Health was built specifically around this stage of life, combining clinical treatment with the kind of real-world skill-building and community that helps young adults not just cope, but move forward.
