How we work
- Public, named sources only, such as federal agencies. Each figure on a study page names its source and period, and every source is linked.
- Our own calculations are labeled as ours, and the method section of each study says how we made them.
- No patient information. These studies use published, aggregate data only.
- Not medical advice. The studies describe care and supply across whole states; they do not say what is right for any one person.
- Spotted an error? Contact us and we will correct it and note the change on the page.
