Mental Health Prevalence Data
The CDC Division of Adult and Community Health and participating state
health departments track adults' perceived mentally and physically unhealthy
days using the Behavioral Risk Factor Surveillance System (BRFSS). The BRFSS,
the world’s largest telephone survey, tracks health risks in the United
States. Information from the survey is used to improve the health of the
American people. Since 1993, the BRFSS has obtained over 1.2 million
responses to the question, "Now thinking about your mental health, which
includes stress, depression, and problems with emotions, for how many days
during the past 30 days was your mental health not good?" Results are
provided in the table below.
