Hazard-zone scores vary sharply by place, from 10.0 in Thatcher to 92.9 in unincorporated Graham County. This contributes to big differences in overall wildfire risk from one neighborhood area to another.

Fire-history scores also swing widely, from 5.0 in unincorporated Graham County to 95.0 near Safford. In this county, past-burn patterns are associated with local differences in present-day wildfire risk scores.

Each bar is what one part of the score covers across Graham County, on the same 0–100 scale. A long bar is a part of the risk that depends on where you are; a short one is the same almost everywhere.

CAL FIRE has no mapped Fire Hazard Severity Zone at 154 of the 154 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At 150 of them the USFS grid above supplied the hazard reading instead; at the remaining 4 the hazard weight is renormalised away rather than scored as low.

154 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 90%. Scores are 0–100 and comparable within the county, not across states.
