What this site is

What's In My County puts public data about each county in the 50 states and the District of Columbia on one map: outbreak signals such as wastewater testing, vaccination coverage and case counts; air quality, drinking water and pollution records; data center locations and permits; and who represents the county.

Every figure keeps its source and its date. A figure published for a whole state or region is labeled as such and never shown as a county's own measurement. Where nothing is published, the page says so.

The site reports public data. It is not medical advice, and nothing on it is a diagnosis, a forecast or a recommendation for any person.

Relationships between measures on the map are associations between places. They do not show that one causes another.

Who publishes it

The site is published by Priori Intelligence. The choice of sources and the plain-language readings are by a research scientist with a doctorate in microbiology, not a physician.

How it is built

Data is fetched from free public feeds, checked by automated quality gates and a consistency audit, and published once a day as plain files. The site has no accounts and no advertising. The rules are on the Methods page, every feed and license is on the Sources page, what is covered is on the Coverage page, and errors can be reported on the Corrections page.
