Understanding These Statistics
Data Sources
The prevalence statistics on this page primarily come from:
- National Survey on Drug Use and Health (NSDUH) — An annual survey of approximately 70,000 Americans, conducted by SAMHSA
- National Institute of Mental Health (NIMH) — Federal agency that provides authoritative prevalence data
- State agency reports — Data from Texas DSHS and related sources
Important Considerations
- "Major depressive episode" is defined using DSM criteria: depressed mood or loss of interest/pleasure plus additional symptoms lasting at least two weeks
- Prevalence estimates can vary based on survey methodology and diagnostic criteria
- Increases in reported depression may reflect actual increases, greater awareness, reduced stigma, or improved screening
- Treatment rates include both medication and therapy but don't measure treatment adequacy or outcomes
