# County Health Rankings

County health measures from the County Health Rankings & Roadmaps analytic data file: premature death, self-reported health, obesity, physical inactivity, provider supply, preventable hospital stays, air pollution, life expectancy and others.

> [!WARNING]
> **Restricted: not available in Cadastre, and will not be served by the API.** Its terms allow personal or non-profit use only; commercial use needs CHR&R's written consent, which Cadastre does not have. It is described here so you know it was reviewed, but its values reach no screen, report or export, and the API will not serve them.

Cadastre shows none of its figures, so no credit is printed for it.

## Measures

These measures are described for reference only: no value of any of them is served.

The key is the measure's identifier in Cadastre. A measure stored for the metro itself is read as stored; **Rule from counties** is how a metro is assembled from its counties where it is not (see [Methodology](https://getcadastre.com/docs/methodology)).

## Known gaps and caveats

- [CDC PLACES](https://getcadastre.com/docs/datasets/cdc-places) is the public-domain source for adult health measures that Cadastre uses instead.
