Published by Hubbub World — health risk data for all US states and counties. Get the bub app for today's data and 30-day forecasts.

Air Pollution risk levels are derived from EPA Air Quality Index (AQI) data, including PM2.5, PM10, ozone, nitrogen dioxide, and sulfur dioxide measurements. Risk scores reflect both current conditions and forecast trends.

Data is updated hourly from EPA monitoring stations and satellite observations.

Frequently Asked Questions

What is Pollution?
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.
How is Pollution risk measured in Ohio?
Pollution risk in Ohio 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.
How is this data collected and updated?
Hubbub World pulls data from multiple authoritative sources: the U.S. Centers for Disease Control and Prevention (CDC) for flu, COVID-19, and RSV surveillance; the U.S. Department of Health and Human Services (HHS) for hospital and community health indicators; the National Oceanic and Atmospheric Administration (NOAA) for weather and air quality; and the American Academy of Allergy, Asthma & Immunology (AAAAI) for allergen reporting. Data is collected continuously from these sources and aggregated to the county and state level on a weekly cadence.
What methodology does Hubbub World use to calculate Pollution risk?
Hubbub World fits 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.
Where can I get current Pollution data for Ohio?
Current Pollution risk levels and 30-day forecasts for Ohio are exclusive to the bub app, available free on iOS, Android, and Apple Watch at https://bub.hubbubworld.com. This web page is the six-week historical archive — the bub app is where today's data and forecasts live.
Is Pollution seasonal in Ohio?
Several of the risks Hubbub World tracks have a seasonal pattern in Ohio — 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 Ohio is reported weekly so seasonal patterns are visible across the six-week archive on this page. For 30-day forward forecasts that show how seasonal patterns are evolving, get the bub app at https://bub.hubbubworld.com.
