Annual state x year intelligence on US federal major-disaster (DR) declarations, 1953 to present, from FEMA's keyless OpenFEMA API v2. Each row is one of 59 states/territories/freely-associated states (plus a US national aggregate row) for one calendar year: distinct DR declaration count (deduped from the one-row-per-designated-area feed by femaDeclarationString), designated-area totals and areas-per-disaster, IA/PA/HM program counts and IA share, hazard-family counts under the connector's closed 9-family taxonomy (tropical-cyclone, severe-storm, flood, winter-storm, wildfire, earthquake, landslide, coastal-storm, other — note 'other' carries the Biological (COVID-19) pandemic declarations) with the dominant family and its share, the year's most common verbatim incident type, year-matched Census population estimates (Vintage 2019 for 2010-2019, Vintage 2025 for 2020-2025; 2026 reuses 2025; null before 2010 and for non-Census-covered areas), disasters per 100,000 people, year-over-year change and a trailing-3-year mean, and two documented 0-100 burden scores (burden_score: mean of within-year min-max-normalized disaster count, designated areas, IA disasters; burden_percap_score: within-year normalized disasters per 100k). Units: counts, percent, per-100k, scores. Caveats: DR declarations only (no emergency/FM); counts are designations, not damage dollars; incidentType is the declaration-level FEMA label. Primary key: (state_code, year). Cadence: yearly; as_of is the latest declaration date in the data, so identical input produces an identical content hash. FEMA records under use-restricted terms (statistical research/reporting only) — commercial_use = unclear with the mandated non-endorsement disclaimer. Sample use: rank burden_percap_score within a year for the states hit hardest relative to population, or track flood_count trends by state.

Column	Type	Description

country_code	string	ISO alpha-3 join key; always USA. (unit: ISO alpha-3)
disaster_count	integer	Distinct major-disaster (DR) declarations signed in the year, deduped by femaDeclarationString. (unit: count)
designated_areas_total	integer	Total designated areas across the year's disasters (distinct designatedArea values). (unit: count)
areas_per_disaster	float	Mean designated areas per disaster; null when the year has no disasters.
ia_disasters	integer	Year's disasters with Individual Assistance declared. (unit: count)
pa_disasters	integer	Year's disasters with Public Assistance declared. (unit: count)
hm_disasters	integer	Year's disasters with Hazard Mitigation declared. (unit: count)
ia_share_pct	float	Share of the year's disasters with Individual Assistance declared (percent). (unit: percent)
tropical_cyclone_count	integer	—
severe_storm_count	integer	—
flood_count	integer	—
winter_storm_count	integer	—
wildfire_count	integer	—

dominant_category	string	Most common of the 9 closed incident categories among the year's disasters.
dominant_category_share_pct	float	Share of the year's disasters in the dominant incident category (percent). (unit: percent)
top_incident_type_raw	string	Most common verbatim FEMA incidentType among the year's disasters.
population	float	Census annual population estimate for the state/year (Vintage 2019 for 2010-2019, Vintage 2025 for 2020-2025; years after the latest vintage reuse it); null before 2010 and for areas the Census state estimates do not cover. (unit: persons)
disasters_per_100k	float	Disaster declarations per 100,000 people (year-matched population). (unit: per 100,000)
disaster_count_yoy_pct	float	Year-over-year change in disaster_count (percent); null when the prior year is 0. (unit: percent)
disasters_3yr_avg	float	Trailing-3-year mean of disaster_count.
burden_score	float	0-100 absolute disaster-burden score: 100 x mean of within-year min-max-normalized disaster_count, designated_areas_total, ia_disasters. Null on national aggregate rows.
burden_percap_score	float	0-100 per-capita disaster-burden score: 100 x within-year min-max-normalized disasters_per_100k; null where population is null.
as_of	string	Latest declaration date in the input data; identical input yields an identical content hash. (unit: date)
source_url	string	OpenFEMA API endpoint behind this dataset. (unit: url)
row_hash	string	SHA-256 (16 hex chars) over the row's content fields. (unit: hash)
