Yes, mental health in the United States is measurably declining. About one in five U.S. adults now experiences symptoms of anxiety or depression, and those numbers have risen significantly in just a few years. The trend affects nearly every demographic group, with young people showing some of the most alarming shifts.
How Much Worse It’s Gotten
Between 2019 and 2022, the percentage of adults reporting anxiety symptoms rose from 15.6% to 18.2%, and depression symptoms climbed from 18.5% to 21.4%, according to CDC data. Those increases may look modest as raw numbers, but they represent millions of additional people experiencing mental distress in a relatively short window.
The pandemic accelerated an already concerning trajectory. Before COVID-19, roughly 11% of adults reported symptoms of anxiety and depression combined. Between April 2020 and February 2023, that figure surged to between 31.5% and 39.3%, depending on the survey period. Rates have come down from those pandemic peaks but remain well above pre-2020 levels, suggesting a lasting shift rather than a temporary spike.
Young People Are Hit Hardest
The numbers among high school students are striking. In 2023, 40% reported persistent feelings of sadness or hopelessness over the past year. One in five seriously considered attempting suicide. Sixteen percent made a suicide plan, and 9% attempted suicide. These aren’t fringe experiences. They describe the reality for a significant portion of American teenagers.
This youth mental health crisis has been building for over a decade, predating the pandemic, though the isolation and disruption of 2020 and 2021 deepened the problem. Adolescents today are navigating social pressures, academic expectations, and digital environments that look fundamentally different from what previous generations faced, and the mental health data reflects that shift.
Suicide Rates Have Plateaued, Not Dropped
The overall age-adjusted suicide rate rose steadily from 2003 to 2018, reaching 14.2 deaths per 100,000 people. Since then, the rate has essentially flatlined. In 2023, it was 14.1 per 100,000, statistically unchanged from 2018. For both men and women individually, rates have held steady since 2017 and 2018 respectively.
A plateau after years of increase is better than continued growth, but it’s not a recovery. The U.S. suicide rate remains historically elevated, and the stabilization hasn’t translated into meaningful improvement. More people are reporting depression and anxiety than ever, which means the underlying pressure hasn’t eased even if the most extreme outcome has leveled off.
What’s Driving the Decline
No single factor explains the trend. Poverty is one of the most powerful predictors of poor mental health, and it compounds nearly every other risk factor: housing insecurity, lack of nutritious food, limited healthcare access, and greater exposure to violence and environmental hazards. Economic inequality creates a baseline of chronic stress that affects tens of millions of Americans.
Discrimination based on race, gender, and sexual orientation worsens mental health outcomes across communities. Adverse childhood experiences, including abuse, neglect, and household dysfunction, disrupt psychological development and increase vulnerability to mental illness later in life. Environmental stressors like pollution, limited access to green space, and climate-related disasters add another layer. These aren’t new problems, but they interact with newer pressures like social media saturation, political polarization, and the lingering effects of the pandemic to create a compounding burden on mental well-being.
Mental Illness and Substance Use Overlap
Roughly 21.2 million U.S. adults have both a mental health disorder and a substance use disorder at the same time, according to a 2024 national survey by the Substance Abuse and Mental Health Services Administration. This overlap is common because people experiencing untreated depression, anxiety, or trauma often turn to alcohol or drugs to manage symptoms. The substance use then creates its own set of problems, making the original mental health condition harder to treat and more likely to worsen. Each condition feeds the other, and addressing only one rarely works.
Half of Those Affected Get No Treatment
In 2022, 59.3 million U.S. adults met the criteria for a mental illness. Only about half of them, 50.6%, received any mental health treatment that year. That means nearly 30 million adults with a diagnosable condition went without care.
Access is a major barrier. More than 137 million Americans live in areas formally designated as Mental Health Professional Shortage Areas, places where there simply aren’t enough providers to meet demand. In many parts of the country, especially rural regions, finding a therapist or psychiatrist who is accepting new patients can take months. Cost, insurance limitations, and stigma keep many others from seeking help even when providers are available. The gap between need and treatment is one of the clearest signs that declining mental health isn’t just a matter of people feeling worse. The system designed to help them can’t keep up.
The Economic Cost
Untreated mental illness costs the U.S. economy an estimated $282 billion per year on average, with 2024 projections reaching approximately $477.5 billion. Those costs come from healthcare spending on conditions that stem from or worsen alongside untreated mental illness, lost workplace productivity, absenteeism, and a phenomenon called presenteeism, where people show up to work but function far below their capacity because of unaddressed psychological distress. Mental health isn’t just a personal struggle. It registers as a measurable drag on the economy, affecting employers, insurers, and public systems alike.
