How this research works
Each study uses public data from government sources such as the CDC, the National Cancer Institute, the Centers for Medicare & Medicaid Services (CMS), the Health Resources and Services Administration (HRSA) and the Substance Abuse and Mental Health Services Administration (SAMHSA). The numbers are computed by scripts from the source files, and the headline figures are checked a second time, against a separate table or query from the same source where one exists. Each figure on a page names its source and the period it covers.
The studies describe populations: how common something is, where, and when. They are not medical advice, they do not make claims about any treatment, and they do not describe the practice's own clients.
Using the data
Reporters, researchers and local organizations are welcome to use these figures. Each study has a CSV download, free to use with credit to Dr. Laura Lehmann, PLLC and a link to the study (CC BY 4.0). Spotted an error? Send a note and it will be corrected, with the change noted on the page.
