The 2026 numbers, checked

The book is right for 2026. This page is right for right now. Every figure names its source and the date it was checked.

Why this page exists. CMS republishes every one of these figures each November for the following year. A printed book cannot change. This page can. When the 2027 numbers are published, this page changes and the book does not need to. Appendix A of your book carries the 2026 figures, and they match what is below, so nothing in your copy is out of date yet.
