What is the prevalence of mental disorders in the US population?

The prevalence of mental disorders in the U.S. population is estimated to be about 1 in 5 individuals. This statistic highlights that mental health issues are quite common, affecting a significant portion of the population. Surveys, such as those conducted by the National Institute of Mental Health (NIMH) and other public health agencies, consistently indicate that approximately 20% of adults will experience some form of mental health disorder in their lifetime.

Understanding this prevalence is crucial because it underscores the importance of mental health awareness, early intervention, and access to care. By recognizing that 1 in 5 people may face mental health challenges, healthcare providers, educators, and community leaders can better prepare to offer support and resources tailored to those in need.
