County-level NFIRS aggregates for 2025, plus 5-year totals across 2021–2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Wildfire risk score (0–100) and Expected Annual Loss come from FEMA's National Risk Index. Drought class is the most recent USDM classification (D0 = abnormally dry through D4 = exceptional drought). Historical fire perimeters are sourced from the NIFC InterAgency Fire Perimeter History.
