The typical city scores 50 for clean air; Santa Ana sits right at the median.

Santa Ana has no air quality measurement yet, so this score is the index median placeholder (≈50), not a measured value. The composite Fun Score renormalises around the gap, so Santa Ana’s headline number is unaffected.

How air quality is measured

Recent particulate matter and ozone levels — a trailing-week air-quality average.

The clean-air score is the flip side of our air quality measure — 100 minus the raw air quality score — so a city with less of it scores higher.

Data sources: EPA AirNow and OpenAQ pollution readings (seven-day trailing average).
