What methodology does Hubbub World use?
Hubbub World develops proprietary models on top of the underlying surveillance, environmental, and weather data to produce comparable risk scores across all U.S. counties. Each of the seven risks is reported on a four-point scale (Low, Moderate, High, Very High) so the scores are interpretable without needing the raw underlying numbers. The full methodology — including the modeling approach, validation against authoritative sources, and known limitations — is documented at https://www.hubbubworld.com/intelligence#methodology.
