In 2025 America retired its 40-year-old fire incident reporting system (NFIRS) and replaced it with NERIS — the National Emergency Response Information System, built by UL's Fire Safety Research Institute with the U.S. Fire Administration. In August 2026 the first large public release arrived: 15 million incident reports, updated multiple times each week.
This atlas is an independent early look at that release. Every bar is a county; every number below comes straight from the public dataset.
When a home burns, the American Red Cross is usually the agency that shows up with shelter and aid. NERIS records, incident by incident, how many people were displaced and whether a smoke alarm was present — the two numbers that tell preparedness programs like Sound the Alarm exactly where working alarms are missing and where families lose their homes.
Every incident carries 45 fields — type, actions taken, coordinates, structure type, smoke-alarm status, displacement, hazards. The NERIS Data Dictionary lists every field with its real-world fill rate and what it means in plain language.
Data: NERIS Public Incident Basics. Incidents are assigned to counties by county name plus state, with a point-in-polygon fallback on incident coordinates. Failed-geocode placeholder coordinates are excluded — including 70,521 dispatch records from 6,107 departments stacked at latitude-longitude (0, 0), the infamous “Null Island” in the Atlantic Ocean where zeroed coordinates land. County population is the 2023 Census estimate. Time Range filters the map to a month span when monthly county totals are in this snapshot; all-time remains the default. Displacement counts people displaced by structure fires only — temporary evacuations logged on wildfire, hazmat, alarm, and medical calls are excluded, because being asked to leave for an afternoon is not losing your home. Reports claiming more than 500 displaced in a single incident are also excluded — a handful of clear data-entry errors (one claimed 75,000; another pasted its incident number into the field) would otherwise dominate the national total. The pinned county details show how many incidents a displacement total comes from. Rendered with deck.gl.
