Score
Low Ozone
Lower EPA 8-hour ozone design-value proxy scores higher using county monitor summaries with fallback.
Higher values rank better for this score.
How It's Calculated
The latest published score is normalized to a 0-100 scale. The method below explains what the score rewards, with technical source metadata available for audit.
How the ranking is built
Low Ozone rewards places with lower ground-level ozone burden.
- 1
The ozone 4th max value is inverse percentile-rank normalized over the full scored distribution.
- 2
Lower ozone burden scores higher.
- 3
County monitor data is preferred
- 4
missing county metrics fall back to state and then national averages with lower confidence.

Statistics Feeding This Score
- Ozone 4th maximumSource: EPA AirData
EPA 8-hour ozone 4th max value, used as a design-value-style annual proxy.
- Monitor countSource: EPA AirData
Number of county monitor rows contributing to the ozone estimate.
- Metric source levelSource: EPA AirData
Whether the ozone value came from county, state, or national fallback data.
Source Data
Known Limits
- EPA AirData is county and monitor based, not a parcel-level exposure model.
- Counties without monitor data use state or national fallback values with lower confidence.
- Annual summaries can miss neighborhood-scale roads, wildfire smoke episodes, indoor filtration, wind patterns, and short-term seasonal variation.
