Caveats

Modelled from monitoring plus maps, weighted by where people live — not one street's reading.
There is no known safe threshold: lower is better all the way down.
Lower means cleaner air on average.

Missing or suppressed values are never shown as zero — every card above passed validation with a real numeric value.
