The 2021 National Survey on Drug Use and Health (NSDUH) used multimode data collection, in which respondents completed the survey in person or via the web.. In 2021, the percentage of adults aged 18 or older with a past year MDE who received treatment for depression in the past year was lower among Black or African American adults (51.0%) than among White adults (64.0%). In 2021, the percentage of adults with any mental illness (AMI) in the past year who received mental health services was lower among Asian (25.4%), Hispanic or Latino (36.1%), or Black or African American adults (39.4%) than among White (52.4%) or Multiracial adults (52.2%). Asian adults with AMI were less likely to have received mental health services compared with adults in most other racial or ethnic groups. Interestingly, the percentage of adults aged 18 or older with serious mental illness (SMI) in the past year who received mental health services in the past year did not differ by racial or ethnic group. These data however overall indicate ongoing and significant health disparities by race/ethnicity.
