About This Directory
Type a name in States, Counties, Regions or Chapters, then check one or more places. Selected names stay visible; use × to remove one. Choices within a list are combined; different lists narrow each other. For example, two states include both, while a county choice limits those states to that county. Clear conflicting choices if places do not overlap. Ask The Data supports combinations up to 500 counties; a single broader region or division remains available. Map selections replace these place filters.
Every U.S. county, with three ways to count a fire department side by side, and the incidents those departments have filed.
Registered Is Not ReportingA department can be on the federal list and still have filed nothing. The Not Reporting column is that gap, county by county — the onboarding signal.
The three counts
NERIS Registered — departments in the current NERIS department directory, the federal list that replaced the USFA registry in 2026. A department's home county is encoded in its NERIS ID (state and county FIPS).
USFA Registered — departments in the USFA National Fire Department Registry, which stopped taking updates in June 2026. Kept because it carries staffing type and organization type in a form NERIS does not.
Reporting — departments that have filed at least one incident in the NERIS public incident export. Total Incidents is everything they filed, all types.
How to use it
Filters live in the left rail, grouped in sections; the count beside each section says how many are on. L opens or closes it. Region and Chapter are type-ahead fields: type part of a name to narrow. Staffing, USFA Organization, and USFA Type are checkbox groups: tick several to include them all, or switch the group to Exclude to hide the ticked ones; Not On File catches departments the source has no value for.
Columns live in the right rail: presets (Core, Incidents, Staffing, All) or pick columns one by one. R opens or closes it. County and department names stay pinned while you scroll sideways; the header stays pinned while you scroll down.
Counties view is one row per county. Click a row to expand its departments; Expand Shown opens every row on the page.
Departments view is one row per department with every field — staffing, stations, USFA type and organization, incident history, website. Paged 400 at a time.
Red Cross Units view is one row per division, region, or chapter over the filtered counties: registrations and the reporting gap from the directory, plus emergency calls, fires, structure fires, people displaced, and the share of structure fires with no smoke alarm by where the call was. Sort by People Displaced and No Smoke Alarm % for Sound the Alarm targeting; the Map colors each unit as a block.
Search matches county, state, department name, city, and NERIS ID. Press / to jump to it. A department match keeps its whole county in view.
Incident Type picks any level of the NERIS type_1 path — a category such as Fire, a type such as Structure Fire, or a subtype such as Room And Contents Fire. A Selected Type column appears with that count for every county and department, sortable and range-filterable. Every type, with its official definition, is in the Incident Type Reference below. Codes greyed out with an asterisk (Not in Public Export) are valid NERIS codes the public data never breaks out: nearly every medical call is published as plain Medical, so Cardiac Arrest, Stroke, Overdose and the rest map empty. Motor Vehicle Collision is the one medical subtype published.

Maps
The Map button turns the current filter into a county map you can print or save. Filter to a state, a Red Cross chapter, a staffing type, or an incident type, press Map, and the counties in that list fill the page.
Measures. Choose what the color means: NERIS registered, USFA registered, reporting, registered but not reporting, the not-reporting share, total incidents, the selected incident type, fires, structure fires, people displaced, stations, or departments per 100,000 residents. In the Departments view the filtered departments roll up by county first, so a staffing or organization filter maps too.
Colors mean the same thing everywhere. Every county in the country is sorted on the chosen measure and split into five equal groups, lightest to darkest. A county keeps its color whether you map one chapter or all fifty states, so a dark county in Maine means the same as a dark county in Texas: it is in the top fifth nationally.
Census Tracts appears when everything on the map sits in one state. Tick it and the counties redraw as Census tracts, the neighborhoods inside them, with their own measures: total incidents, medical, fires, residential fires, structure fires, people displaced, and the share of structure fires with no smoke alarm present. Each incident counts for the tract its reported location falls in, so a tract map is by where the call was, not by the department's home county. Hover a tract for its number, county and value; on a phone, pinch to zoom and tap a county or tract for the same detail. Tract colors follow the same national five-group rule. Tract data is a dated build from the public export (the date is in the map's source line); counties still refresh nightly.
Scale To This Map changes the yardstick. Tick it and the five groups are made from only the counties on the map, so the darkest color goes to the highest counties in this area even if they would be pale on a national map. Use it to see contrast inside one chapter; leave it off to compare places fairly. The legend always says which is in use.
Counts versus shares. Raw counts favor counties with many departments. Not Reporting Share divides the gap by registered departments and is the fair comparison across county sizes.
What you see. County names appear when there is room; surrounding counties show in faint gray for bearings; a heavy outline traces the edge of the filtered area. National views draw the lower 48 with Alaska, Hawaii, and Puerto Rico as insets.
Report page. Below the map, and as page two when printed, a profile of the mapped area: 22 cards such as emergency calls, medical share, structure fires by building type, people displaced, no-smoke-alarm and no-sprinkler shares, crashes, rescues, hazmat, acres burned, mutual aid, and calls per 1,000 residents, each against the national figure. Untick Report Page for the map alone.
Output.Print / Save PDF prints the figure and the report page, landscape, with title, legend, and source line. Download PNG saves a 2,200-pixel image of the map. On a phone, pinch to zoom, pan when zoomed, and tap a county or tract for its name and value; print and PNG still save the full fitted map.
Read it carefully. Incidents sit in the county where the department is registered, not where the call was; a big regional department's calls all land in its home county. Gray means no department there is filing yet, not zero incidents. Type-specific maps can carry coding errors while departments learn the new codes: a landlocked Texas county reporting 139 watercraft rescues is a misfiled code, not boats.
Definitions
Staffing and Stations come from each NERIS department page: Career, Combination, or Volunteer, and the station count the department entered.
USFA Type is USFA's career share: Career, Mostly Career, Mostly Volunteer, Volunteer. USFA Org is local, state, federal, tribal, airport, private, or contract.
Fires, Structure Fires, and Medical are the top NERIS categories. Displaced counts people displaced by structure fires only.
Depts / 100k divides the larger of the two registry counts by 2023 residents.
Time Range re-sums incidents, fires, structure fires, medical calls and displaced people to a span of months, and Reporting becomes "filed at least one incident in that span". Play Months steps one month at a time. First Call, Last Call and Selected Type Incidents always cover the whole record.
First Call and Last Call bracket the incidents on file — a recent first call usually means recent onboarding, not a new department.
Limitations
USFA rows are matched to NERIS rows by county and name. Unmatched USFA departments appear as USFA-only rows, so a few departments show twice under different spellings.
Big-city departments register under one county and serve several; FDNY sits in Kings County.
Connecticut uses legacy county codes in both registries but planning regions in the Red Cross spine, so its chapter column is blank. Puerto Rico and Guam each roll up to one row.
NERIS is still onboarding: low incident numbers can mean low reporting, not low need.
Incident Type Reference
Every NERIS incident type, organized the way the picker is: category, type, subtype. Definitions and examples are NERIS's own, from Appendix B of the User Reference Guide; counts are incidents filed nationally in the public export. Filter applies that type to the table.
Data and refresh
Incidents come from the NERIS public incident export and refresh nightly with the rest of neris.jbf.com. The two registries are re-crawled every month or two. Red Cross chapter, region, division, and population come from the governed Red Cross geographic spine, joined on FIPS. Independent and unofficial.
