The National Survey on Drug Use and Health found that 14.2 million or 5.6% of non-institutionalized, non-homeless U.S. adults had a "serious mental illness" in 2020 that "substantially interfered with or limited one or more major life activities." This data is based on a nationally representative survey of about 50,625 adults.
