Pollution in Louisiana

Pollution risk reflects local air quality, primarily driven by fine particulate matter (PM2.5), ground-level ozone, and other common air pollutants. Higher risk levels indicate poorer air quality and a greater chance of respiratory irritation, especially for sensitive groups like people with asthma, children, and older adults.

Pollution risk in Louisiana is reported as a weekly score on a four-point scale: Low, Moderate, High, and Very High. The score reflects the modeled burden of Pollution across the state, validated against public health data from CDC, HHS, NOAA, and other authoritative sources. Methodology details are available at https://www.hubbubworld.com/intelligence#methodology.

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.

Several of the risks Hubbub World tracks have a seasonal pattern in Louisiana — 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 calendar. Pollution risk in Louisiana is reported weekly so seasonal patterns are visible across the six-week archive on this page.
