State totals reflect incidents reported by fire departments to NFIRS for 2025. The 5-year totals span 2021 through 2025. Wildfire perimeters and decade-by-decade counts are sourced from the NIFC InterAgency Fire Perimeter History service. NFIRS reporting is voluntary, so totals are a strong indicator rather than a complete census.
