A teen can be struggling without a recorded diagnosis, and a diagnosis does not describe every part of their life. In the 2023 national high school survey, 39.7% reported persistent sadness or hopelessness. Separate household surveys measure depressive episodes, anxiety symptoms and treatment access. Their different answers reflect different questions and groups of young people.

How common mental health conditions are in teens
There is no single percentage that captures every kind of mental health difficulty. A household survey can count diagnosed conditions, while a school survey captures distress that may never reach a clinic. Age ranges and time windows also matter: a lifetime history answers a different question from symptoms during a recent fortnight.
Persistent sadness or hopelessness among high school students in 2023
The Youth Risk Behavior Survey asked about feeling so sad or hopeless almost every day for at least two consecutive weeks that students stopped some usual activities during the previous year. The result reflects disruption to ordinary life, without establishing a diagnosis of depression. Because the survey takes place in schools, its estimate describes enrolled high school students; young people outside that setting may have different experiences.
| 28.5% | Poor mental health in the past month, high school students, 2023 Students selected “most of the time” or “always” when describing poor mental health, giving a shorter view of distress than the sadness question and including experiences beyond depression. |
| 20.3% | Current diagnosed anxiety, depression or behavior problems, ages 12 to 17, 2023 Parents reported whether a clinician had identified one of these conditions and whether it was still present, so the estimate depends partly on recognition and access to assessment. |
| 3.8 million | Adolescents ages 12 to 17 with a depressive episode in 2024 This population estimate translates the NSDUH percentage into people, emphasizing how many families encounter a sustained cluster of depressive symptoms over the course of a year. |
| 49.5% | Any lifetime mental disorder, ages 13 to 18, 2001 to 2004 The NIMH figure comes from diagnostic interviews in the National Comorbidity Survey Adolescent Supplement and remains a historical benchmark rather than a measurement of teens in 2026. |
| 61% | Children ages 6 to 17 meeting all flourishing indicators, 2023 to 2024 Parent reports assessed curiosity, completing tasks and staying calm during challenges, showing that positive functioning can be measured alongside difficulties, although this broader age group includes younger children. |
| 11% | Current diagnosed anxiety, children ages 3 to 17, 2023 to 2024 The much wider childhood age range helps explain why this percentage differs from a teen-only estimate; the two denominators should remain visible whenever the figures are compared. |
Additional measures across childhood and adolescence
| Measure and population | Figure | Meaning and source |
|---|---|---|
| Current diagnosed depression, ages 3 to 17, 2023 to 2024 | 4% | Parent reports capture recognized conditions across childhood; this percentage is not a teen-only prevalence estimate. CDC children mental health data, NSCH |
| Current diagnosed behavior disorders, ages 3 to 17, 2023 to 2024 | 8% | This category adds a different part of mental health need and overlaps with other conditions in some children. CDC children mental health data, NSCH |
| Lifetime anxiety disorders, ages 13 to 18, 2001 to 2004 | 31.9% | The historical interview survey counts any qualifying anxiety disorder experienced before the interview, even if it had since improved. NIMH Any Anxiety Disorder |
Why these percentages should stay separate
The same adolescent can appear in several categories: a diagnosed anxiety disorder, a depressive episode during the year, and a period of persistent sadness. Adding the percentages would count some people repeatedly. Conversely, having no recorded diagnosis can reflect either good mental health or a difficulty that has not been assessed. Parent surveys offer insight into recognized needs, while confidential teen questionnaires give young people room to describe their own experience. Together they show several dimensions of mental health, including symptoms, functioning and contact with care. HRSA survey definitions; CDC survey definitions.
Depression and anxiety in teens
Depression and anxiety statistics depend on both symptom severity and the period being measured. The newest NSDUH estimates used here cover depressive episodes over a year and anxiety symptoms over two weeks. Parent-reported diagnoses add another perspective on conditions that have reached professional attention and are still considered present.
Adolescents had a past-year major depressive episode in 2024
SAMHSA classified an episode using a sustained period of depressed mood or lost interest together with other symptoms, such as changes in sleep, energy or concentration. The estimate covers adolescents ages 12 to 17 living in the civilian, noninstitutionalized population. It can include young people who never received a formal diagnosis or treatment. This is why the figure is especially useful for estimating the scale of depression-related need beyond existing patient records.
| 11.3% | Depressive episode with severe impairment, all adolescents, 2024 The denominator is all adolescents ages 12 to 17, and severe impairment refers to substantial difficulty in home tasks, school or work, family relationships, or social life. |
| 18.8% | Moderate or severe anxiety symptoms, ages 12 to 17, 2024 The GAD-7 questionnaire measures recent symptom severity, so this result identifies elevated symptoms without confirming a generalized anxiety disorder diagnosis through a clinical interview. |
| 23.1% | Mild anxiety symptoms, ages 12 to 17, 2024 Mild scores describe a separate severity category and illustrate why combining every symptom level into one headline can obscure meaningful differences in the burden teens report. |
| 8.2% | Severe anxiety symptoms, ages 12 to 17, 2024 These respondents fall within the combined moderate-or-severe total, making this a subgroup of the higher-severity estimate rather than an additional group to add to it. |
| 16.1% | Current diagnosed anxiety, ages 12 to 17, 2023 The NSCH parent-reported estimate identifies recognized anxiety problems, offering a useful complement to symptom screening because it reflects a different route into being counted. |
| 8.4% | Current diagnosed depression, ages 12 to 17, 2023 Parents were asked about a diagnosis and whether depression was currently present, which makes this measure narrower in timing and recognition than a past-year episode. |
Other symptom surveys with different populations
| Measure and population | Figure | Meaning and source |
|---|---|---|
| Recent anxiety symptoms, NHIS-Teen, 2021 to 2023 | 20% | The national teen survey asked adolescents ages 12 to 17 directly about the previous two weeks. CDC children mental health data, NHIS-Teen |
| Recent depression symptoms, NHIS-Teen, 2021 to 2023 | 18% | A short symptom window can miss an earlier episode that would still count in a past-year measure. CDC children mental health data, NHIS-Teen |
| Elevated depression symptoms in international pandemic studies, 2020 to early 2021 | 25.2% | The pooled estimate comes from studies of children and adolescents during an exceptional period. Racine et al., JAMA Pediatrics, 2021 |
| Elevated anxiety symptoms in the same pandemic meta-analysis | 20.5% | Differences among countries, samples and screening tools limit how closely this estimate describes any particular school or community. Racine et al., JAMA Pediatrics, 2021 |
Symptoms and daily functioning are different measurements
A symptom score describes the experiences a person reports, while an impairment measure asks how much those experiences disrupt everyday roles. Both matter for understanding population need. A parent may notice school or household difficulties before knowing what a teen is feeling; a teen may describe distress before it becomes visible to others. The international pandemic estimates also combine younger children with adolescents and varied research settings, so they provide historical context rather than a current U.S. prevalence rate. SAMHSA measurement notes.
Psychology.com’s depression questionnaire and anxiety questionnaire use symptom questions; their results are a different kind of information from a population prevalence estimate or a professional diagnosis.
Teen suicide and self-harm
Thoughts of suicide, suicide attempts and nonsuicidal self-injury describe different experiences. Surveys can document how often students report them, but cannot predict what an individual will do. The distinctions matter for families, schools and reporting: these figures show prevention needs while leaving room for support, change and recovery.
High school students seriously considered attempting suicide in 2023
The CDC estimate refers to the previous year and to a specific self-report question about seriously considering an attempt. It describes thoughts rather than deaths, and it cannot be converted into a suicide mortality rate. Population findings help identify the reach of prevention needs, but they do not assign an outcome to any particular teen.
| 27.1% | Female students reporting serious consideration, 2023 The higher prevalence among female students is a difference in self-reported thoughts during the previous year, and should be described separately from differences in suicide mortality. |
| 14.1% | Male students reporting serious consideration, 2023 A lower group average still represents substantial distress among male students and offers no basis for discounting an individual student’s experience or need for support. |
| 12.6% | Female students reporting an attempt, 2023 This past-year survey measure counts students reporting at least one attempt, so it describes people rather than the number of events or emergency department visits. |
| 6.4% | Male students reporting an attempt, 2023 The estimate uses the same question and time window as the female-student measure, allowing comparison within the survey while leaving clinical circumstances and outcomes unspecified. |
| 41.0% | LGBQ+ students reporting serious consideration, 2023 This sexual-identity grouping includes lesbian, gay, bisexual, questioning and other nonheterosexual identities, and CDC discusses the result alongside rejection, discrimination and other sources of stress. |
| 13.0% | Heterosexual students reporting serious consideration, 2023 The comparison describes a disparity between groups in the same school survey; it does not establish that sexual identity itself causes suicidal thoughts. |
Measures that answer different questions
| Measure and population | Figure | Meaning and source |
|---|---|---|
| All high school students reporting an attempt, past year, 2023 | 9.5% | This measure should remain separate from thinking about an attempt and from the number of suicide deaths. Verlenden et al., CDC MMWR, 2024 |
| Pooled adolescent nonsuicidal self-injury prevalence, studies published 2000 to 2022 | 17.7% | The meta-analysis included ages 10 to 19 across 17 countries; its pooled estimate is not a current U.S. teen rate. Moloney et al., JAMA Network Open, 2024 |
| Adjusted prevalence ratios associated with high school connectedness, 2023 | 0.63 to 0.70 | Across four outcomes, students feeling closer to people at school reported lower prevalence than the comparison group. Verlenden et al., CDC MMWR, 2024 |
How to describe self-harm without implying an outcome
The self-injury meta-analysis defined its outcome as behavior occurring without suicidal intent. That distinction does not make the experience trivial, and it also means the estimate cannot be substituted for an attempt rate. The studies varied in location, design and measurement, making the pooled figure a broad research summary. The source does not present it as a current annual U.S. prevalence rate. In CDC’s school data, connectedness and supportive family circumstances were associated with lower prevalence of several risk indicators. Because these were observational comparisons, they do not show how much changing one circumstance would change a particular student’s risk. Moloney and colleagues; CDC protective-factor analysis.
Who is most affected
National averages hide important differences in reported distress. Female students, sexual-minority students and transgender students often report greater burdens, although these categories overlap. The surveys describe experiences within social settings, including safety and belonging. Their results support attention to unequal conditions without treating any identity as an explanation on its own.
Female high school students reported persistent sadness or hopelessness in 2023
The CDC result uses the same past-year question for all students and reflects feelings that interrupted usual activities. Sex differences appear across several measures, but the size of a difference depends on the outcome being studied. Reading those findings together requires care because the groups overlap and are not interchangeable.
| 27.7% | Male students with persistent sadness or hopelessness, 2023 The male-student result shows that substantial distress extends across sex categories, even though the survey found a higher prevalence among female students. |
| 38.8% | Female students with poor mental health, 2023 This shorter measure concerns mental health during the previous month, making it a different view of the burden from sadness that occurred at any point during the year. |
| 18.8% | Male students with poor mental health, 2023 Using the same recent-period question helps make the sex comparison consistent, while leaving differences in symptom recognition and willingness to report outside the estimate. |
| 65.7% | LGBQ+ students with persistent sadness or hopelessness, 2023 The elevated prevalence reflects the experiences of a diverse sexual-minority group and should be understood alongside social stressors rather than as an inherent feature of identity. |
| 31.4% | Heterosexual students with persistent sadness or hopelessness, 2023 This comparison comes from the same national survey and demonstrates how much an overall average can conceal when groups report different levels of distress. |
| 71.9% | Adjusted prevalence of persistent sadness or hopelessness among transgender students, 2023 This estimate was adjusted for race and ethnicity and grade, so it should retain that label when compared with the unadjusted figures in other CDC analyses. |
Additional disparities within the 2023 national high school survey
| Measure and population | Figure | Meaning and source |
|---|---|---|
| Poor mental health in the past month, LGBQ+ students | 53.5% | The shorter time window still shows a substantial reported burden. Verlenden et al., CDC MMWR, 2024 |
| Poor mental health in the past month, heterosexual students | 21.5% | The comparator uses the same question and response categories. Verlenden et al., CDC MMWR, 2024 |
| Past-year attempt, LGBQ+ students | 19.7% | This disparity concerns self-reported behavior and does not establish an individual prognosis. Verlenden et al., CDC MMWR, 2024 |
| Past-year attempt, heterosexual students | 6.0% | The percentage describes the same outcome in the comparison group. Verlenden et al., CDC MMWR, 2024 |
What the Trevor Project survey adds
The Trevor Project’s 2024 report, based on an online sample recruited in 2023, provides detail about LGBTQ+ young people’s experiences. Among respondents ages 13 to 17, in-person bullying was reported by 49% and electronic bullying by 35%. Across respondents ages 13 to 24, recent anxiety symptoms were reported by 66% and depression symptoms by 53%. These findings describe the recruited sample, which included young adults and was not a national probability sample of all LGBTQ+ teens. Trevor Project survey and methods.
Psychology.com’s parenting resources provide additional context for family conversations about young people’s emotional lives, school experiences and relationships.
Treatment and the care gap
Treatment statistics depend on who is included and what counts as care. A percentage among teens with depression differs from a percentage among all students. Surveys also distinguish receiving some help, wanting help, and having difficulty obtaining it. Each highlights a distinct part of access.
Adolescents with a past-year depressive episode received mental health treatment in 2024
The NSDUH measure includes inpatient or outpatient care, prescribed medication, telehealth and treatment in correctional settings. It records whether any qualifying care occurred during the previous year, without establishing that it was sufficient, continuous or specifically for depression. Some adolescents used more than one type of care, so the treatment categories overlap. The result leaves a substantial group with a depressive episode and no qualifying mental health treatment.
| 50.8% | Outpatient treatment among adolescents ages 12 to 17 with a past-year depressive episode, 2024 This includes care outside an inpatient admission and represents one part of the broader treatment measure, rather than a separate population to add to it. |
| 33.2% | Telehealth among adolescents ages 12 to 17 with a past-year depressive episode, 2024 Remote delivery can overlap with outpatient counseling or other treatment, so it describes how care was accessed as well as whether contact occurred. |
| 31.2% | Prescribed mental health medication among adolescents ages 12 to 17 with a past-year depressive episode, 2024 Medication receipt does not identify the specific condition treated, the medication used or whether symptoms improved, and can coincide with counseling. |
| 28.5% | Any mental health treatment among all adolescents, 2024 This broader denominator includes adolescents with other conditions or needs, illustrating why it cannot be read as the treatment rate for depression. |
| 47% | Public schools reporting capacity to serve all students in need, March 2024 This is the combined agreement estimate in NCES’s current School Pulse Panel results file. It differs from the 48% in the original release and measures schools’ reported capacity, rather than individual students’ receipt of help. |
| 61.0% | Difficulty obtaining needed care among diagnosed adolescents, 2023 Parents reported access difficulties among adolescents with a current diagnosis who needed treatment; someone could ultimately receive care and still face substantial difficulty obtaining it. |
Three views of service availability
| Measure and population | Figure | Meaning and source |
|---|---|---|
| Public K-12 schools offering some mental health service, 2024 | 97% | Offering a service does not establish enough capacity for every student needing it. NCES School Pulse Panel, March 2024 data in the current results file |
| Public schools reporting staffing limits, 2024 | 55% | Insufficient mental health staff coverage was a common barrier to meeting student needs. NCES School Pulse Panel, March 2024 data in the current results file |
| Adolescents reporting unmet needs, NHIS-Teen, 2021 to 2023 | 20% | Young people’s own reports capture a different perspective from school or parent assessments. CDC children mental health data, NHIS-Teen |
Privacy and expectations can shape access
Among untreated adolescents with a past-year depressive episode and perceived unmet need in 2024, 90.5% said they thought they should handle their concerns themselves, and 64.9% worried information would not remain private. Both percentages use this restricted group as their denominator. SAMHSA access questions. In the Trevor Project’s 2023 online sample of LGBTQ+ respondents ages 13 to 24, 84% wanted care, 42% received counseling, and 50% of those wanting care could not obtain it. Trevor Project, 2024.
Psychology.com’s child therapy resources explain the context of services for young people and families; the national percentages above describe access across many different care settings.
Trends over time
Recent findings show both improvement and continued need. Comparable NSDUH estimates of adolescent depressive episodes declined after 2021, while parent-reported diagnoses had risen over a longer period. Changes in survey methods, service use and recognition can affect these patterns. The data years below remain separate from this page’s 2026 publication date.
Past-year adolescent depression declined to 15.4% in 2024
In the comparable NSDUH series, past-year major depressive episodes fell from 20.8% in 2021. SAMHSA revised the 2021 survey weights for comparisons with later years, so the earlier published NIMH estimate of 20.1% should not be substituted into this trend. These results describe separate samples of adolescents over time; they cannot establish how many individual teens recovered or which experiences explain the population change. NIMH’s original 2021 estimate.
| 19.5% | Adolescent depressive episodes in 2022 This estimate belongs to the comparable series in SAMHSA’s 2024 report, keeping the historical measurement consistent with the later observations. |
| 18.1% | Adolescent depressive episodes in 2023 The household survey continued to show a substantial burden even as the comparable series moved downward from its 2021 level. |
| 61% | Increase in diagnosed adolescent anxiety, 2016 to 2023 HRSA reports a relative increase in parent-reported current diagnoses, which can reflect changes in underlying need alongside changes in recognition and assessment. |
| 60.0% | Increase in diagnosed depression prevalence, 2017 to 2021 The Southern California health-system study included insured patients ages 5 to 22, making its regional findings informative without representing every U.S. teen. |
| 31% | Relative increase in the mental health share of ED visits, ages 12 to 17, 2020 versus 2019 CDC compared weeks 12 to 42 in reporting emergency departments. The finding concerns the proportion of visits, which can rise when other emergency visits fall, without an equivalent rise in mental health visit counts. |
| 38% | Moderate or severe depressive symptoms among college students, 2023 to 2024 The Healthy Minds Study’s weighted estimate covers participating college and university students ages 18 and older, including graduate students. It reflects a PHQ-9 score of at least 10 over the previous two weeks and provides college-transition context beyond the teen years. |
Persistent sadness or hopelessness in national high school surveys
| Measure and population | Figure | Meaning and source |
|---|---|---|
| 2019 YRBS, before the pandemic | 36.7% | The measure asked about a sustained period of sadness affecting usual activities during the preceding year. Bitsko et al., CDC MMWR, 2022 |
| 2021 YRBS, summarized in CDC’s 2024 report | Over 42% | Reported sadness was above the earlier level during the pandemic period. CDC MMWR, 2024, describing 2021 YRBS |
| 2023 YRBS | 39.7% | The later estimate remained above the 2019 figure despite being below the pandemic-period summary. Verlenden et al., CDC MMWR, 2024 |
What a timeline can establish
The Surgeon General’s 2021 advisory described disrupted schooling, reduced social contact, interrupted services and bereavement as part of the pandemic context. It cited more than 140,000 U.S. children losing a parent or grandparent caregiver by June 2021. That estimate helps describe the period without attributing every later mental health change to one cause. Surgeon General advisory, 2021. Annual surveys can identify changing patterns, but they do not isolate the contributions of the pandemic, social conditions, school experiences or technology.

Social media and screens
Screen time includes many different activities, from messaging a friend to watching videos or completing homework. Social media research adds further distinctions between frequency, duration, content and personal experience. A high-use percentage says how common an exposure is; understanding its relationship with mental health requires a different kind of study.
High school students used social media several times daily or more in 2023
CDC’s frequency question grouped students using social media several times a day, about hourly or more than hourly. It did not measure total hours or diagnose problematic use. Frequent use was associated with persistent sadness and some other adverse experiences in this survey, but exposure and outcomes were reported at the same time. That design cannot establish which came first or how much other circumstances contributed to the association.
Why hours alone do not explain the association
The Riehm study followed U.S. young people across survey waves and adjusted for measured background differences. The quoted estimate concerns internalizing problems alone, a separate category from co-occurring internalizing and externalizing problems. Internalizing problems include difficulties such as depression and anxiety; the relative risk ratio is a measure of association. Adjustment reduces some alternative explanations, while unmeasured differences and changes in use remain possible. The estimate should therefore retain its outcome, comparison group and historical data period. Different findings can also emerge when studies ask about total time, specific online experiences or a teen’s own evaluation of how a platform affects them. Riehm and colleagues, 2019.
Connection, content and uncertainty
The Surgeon General’s 2023 advisory cited social media use among up to 95% of young people ages 13 to 17 from a 2022 survey and emphasized gaps in independent safety research. Surgeon General advisory, 2023. The reach of these platforms makes their design and content relevant to population health, but widespread use by itself does not establish harm. Teenagers can experience support, exclusion, creativity and pressure in different online settings. A single total for screen hours cannot identify which of those experiences mattered for a particular young person.
