Pollution in Montana

Pollution prevalence is the number of people impacted by pollution from particulate matter and gases in a neighborhood. It gives an idea of how many people are suffering from airborne pollution in an area at a given time.

Pollution prevalence in Montana is reported as the peak weekly score of how many people are impacted in a neighborhood, on a five-point scale: Low (<5), Moderate (5–15), High (15–25), Very High (25–40) and Extreme (>40). The score reflects the highest number of people impacted by Pollution across neighborhoods in the state, validated against public health data from CDC, HHS, EPA, NOAA, and other authoritative sources. Methodology details are available at https://www.hubbubworld.com/intelligence#methodology.

Hubbub develops proprietary models on top of geographic, demographic, environmental, surveillance and weather data to produce prevalence scores across the U.S. Prevalence is reported on a five-point scale (Low, Moderate, High, Very High, Extreme) 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.

Several of the risks Hubbub tracks have a seasonal pattern in Montana — flu and RSV typically peak in fall and winter, allergies vary with tree, grass, and weed pollen seasons, and severe weather risks shift with the seasons. Pollution prevalence in Montana is reported weekly, so seasonal patterns are visible across the 4-week archive on this page.
