Mental Health Statistics
By the numbers
Millions of people in the U.S. are affected by mental illness each year. It’s important to measure how common mental illness is, so we can understand its physical, social and financial impact — and so we can show that no one is alone. These numbers are also powerful tools for raising public awareness, stigma-busting and advocating for better health care.

Types of mental illnesses
- The National Alliance on Mental Illness (NAMI) recognizes a range of mental health conditions, including depression, anxiety disorders, bipolar disorder, schizophrenia, Obsessive Compulstive Disorder (OCD), Post Traumatic Stress Disorder (PTSD), Attention Deficitive Hyperactivity Disorder (ADHD), and eating disorders. A mental illness is a medical condition that affects a person's thinking, feeling, mood, ability to relate to others, and daily functioning, but NAMI emphasizes that recovery is possible through treatment.
