This page pulls together current teen mental health statistics from federal and peer-reviewed sources in one place, cited so parents, clinicians, and writers can verify every figure. Each statistic links to its source, and the full source list appears at the bottom of the page.

Where These Numbers Come From

Three federal data sources produce most reliable teen mental health data, and they measure different things. The CDC’s Youth Risk Behavior Survey (YRBS) surveys high school students directly about experiences like persistent sadness, so it captures self-reported distress rather than diagnoses. The National Survey on Drug Use and Health (NSDUH) interviews households annually and estimates diagnosable conditions like major depressive episodes. The National Comorbidity Survey Adolescent Supplement (NCS-A) remains the benchmark for lifetime prevalence of adolescent mental disorders.

Knowing the source matters when figures seem to conflict. A statistic saying 40% of students report persistent sadness and another saying 20% of adolescents had a major depressive episode are both correct. They are measuring different things.

Teen Anxiety Statistics

Anxiety disorders are the most common mental health conditions among adolescents.

  • An estimated 31.9% of adolescents ages 13 to 18 experience an anxiety disorder at some point, according to the National Institute of Mental Health, drawing on the National Comorbidity Survey Adolescent Supplement.
  • Prevalence is higher among girls (38.0%) than boys (26.1%) in the same dataset.
  • Among adolescents with an anxiety disorder, an estimated 8.3% experience severe impairment, per NIMH.

Anxiety this common is easy to dismiss as normal teenage stress. The impairment figure is the useful check: for a meaningful share of teens, anxiety limits daily functioning rather than just accompanying it.

Teen Depression Statistics

Depression figures come primarily from the National Survey on Drug Use and Health (NSDUH) and the CDC’s Youth Risk Behavior Survey.

  • An estimated 20.1% of adolescents ages 12 to 17, about 5 million teens, experienced a major depressive episode in the past year, according to NIMH’s summary of 2021 NSDUH data.
  • The gap by sex is wide: 29.2% of adolescent girls experienced a major depressive episode versus 11.5% of boys, per NIMH.
  • 14.7% of adolescents experienced a major depressive episode with severe impairment, per NIMH.
  • In the CDC’s 2023 Youth Risk Behavior Survey, 40% of high school students reported persistent feelings of sadness or hopelessness, including 53% of teen girls.
  • In the same CDC survey, 27% of teen girls reported seriously considering suicide.

The 2023 YRBS numbers improved slightly from 2021, when 42% of students overall and 57% of girls reported persistent sadness or hopelessness. The trend line matters, but the levels remain far above where they stood a decade ago.

Teen ADHD Statistics

ADHD is among the most commonly diagnosed neurodevelopmental conditions in adolescents.

  • An estimated 7 million U.S. children ages 3 to 17, or 11.7%, have a current ADHD diagnosis, according to the CDC.
  • Boys are diagnosed at roughly twice the rate of girls, 13% versus 7%, per CDC data, a gap driven partly by how differently symptoms present in girls.
  • Nearly 78% of children with ADHD have at least one co-occurring condition, with behavioral problems and anxiety the most common, per the CDC.
  • About 30% of children with current ADHD receive neither medication nor behavioral treatment, per the CDC.

Teen Trauma and PTSD Statistics

Trauma exposure in childhood is far more common than most parents expect.

  • In a large longitudinal study published in the Archives of General Psychiatry, about two-thirds of children reported at least one potentially traumatic event by age 16 (Copeland et al., 2007).
  • An estimated 5.0% of adolescents ages 13 to 18 meet criteria for PTSD at some point, according to NIMH, with prevalence far higher among girls (8.0%) than boys (2.3%).
  • Among adolescents, an estimated 1.5% experience PTSD with severe impairment, per NIMH.

Exposure is not the same as disorder. Most teens who experience a traumatic event do not develop PTSD, but the exposure numbers explain why trauma screening belongs in any thorough mental health evaluation.

The Treatment Gap

Across conditions, the most consistent finding is the distance between how many teens struggle and how many get help.

  • Fewer than half of adolescents with a major depressive episode, 40.6%, received treatment in the past year, per NIMH. Even among teens whose depression caused severe impairment, only 44.2% received treatment.
  • About 30% of children with a current ADHD diagnosis receive neither medication nor behavioral treatment, per the CDC.

These are teens whose conditions were identifiable in a survey, which means the true gap, including teens never evaluated at all, is likely wider.

Is Teen Mental Health Improving?

Slightly, from a difficult peak. Comparing the CDC’s 2023 YRBS against 2021: persistent sadness or hopelessness fell from 42% to 40% of students overall, and from 57% to 53% among girls. The share of girls who seriously considered suicide fell from 30% to 27%.

Those are real improvements, and they still leave levels well above where they stood a decade earlier. The honest reading is a crisis that has stopped worsening rather than one that has resolved, with teen girls continuing to carry a disproportionate share of it.

What the Numbers Mean for a Parent Evaluating Care

Three practical takeaways sit behind these statistics.

Your family is not an outlier. With one in five teens experiencing a major depressive episode in a year and nearly one in three experiencing an anxiety disorder in adolescence, struggling is common, and so is recovering with the right support.

The treatment gap is the real risk. The starkest numbers on this page are the ones about who gets help. Conditions that go untreated through adolescence tend to compound, affecting school, relationships, and self-image along the way.

Co-occurrence is the rule, not the exception. ADHD travels with anxiety, depression travels with trauma, and a single-condition explanation is often incomplete. When you seek an evaluation for your teen, ask for one broad enough to catch what else may be present.

If the numbers on this page describe what you are seeing at home, our admissions team can help you figure out what level of support fits your teen’s situation.

Using and Citing These Statistics

Writers, clinicians, and educators are welcome to cite this page. Two requests keep the numbers honest. First, cite the original source for each figure, which is why every statistic above links to one; this page is a compilation, and the CDC, NIMH, and the underlying studies are the authorities. Second, keep measurements distinct: self-reported sadness from the YRBS, past-year major depressive episodes from the NSDUH, and lifetime prevalence from the NCS-A answer different questions, and blending them produces statistics that sound dramatic and mean nothing.

If a figure on this page no longer matches its source, the source has been updated and takes precedence.

Sources

Statistics reflect the most recent figures published by each source as of September 2026. Survey years vary by source and are noted where relevant.
