What this measures

Air quality from monitors and the damage natural disasters are expected to do to buildings each year, flipped so higher is better. It covers only counties with an air monitor, about one in four. The county's own model of fine dust is left out, since it is fitted to the same monitors. Source: PlaceStats composite score.
