One row per (U.S. county, NRI hazard family) for the 18 FEMA National Risk Index v1.20 (Dec 2025) hazards: hazard risk score (0–100 national percentile) and rating, expected annual loss (total/buildings/population/agriculture, USD) with each hazard's share of the county's total EAL and rank-in-county, dominant hazard per county + its EAL share, county EAL per capita and as a share of building value, Very-High rating ordinals, a multi-hazard hotspot flag (>=2 Very High hazards), social vulnerability and community resilience scores/ratings, and the hazard's documented period of record. 88 insufficient-data counties are kept as coverage-transparent null rows. Primary key: (county_fips, hazard_code). Join keys: county_fips (5-char GEOID), hazard_code. Cadence: quarterly (version-pinned; re-ingests as a no-op until FEMA publishes a new NRI version). FEMA NRI data is U.S. public domain — commercial_use = yes. Sample use: filter multi_hazard_hotspot and order by county_eal_per_capita_usd desc for the riskiest compound-risk counties per resident.

Column	Type	Description
as_of	string	Last complete UTC day of the fetch. Fixed per run, so an unchanged NRI release re-ingests as a no-op. (unit: date)
nri_version	string	Pinned NRI release version (1.20); the snapshot supersedes only when FEMA publishes a new version.
county_fips	string	5-char county GEOID (STCOFIPS zero-padded). Join key. (unit: id)
county_name	string	County/equivalent name from the NRI table.
county_type	string	FEMA county-equivalent type (County, Borough, Parish, Municipio, …).
state_name	string	State/territory name.
state_abbr	string	USPS state/territory abbreviation. (unit: code)
country	string	Canonical country name (United States).
country_code	string	ISO alpha-3 country code (USA). Join key. (unit: code)
hazard_code	string	NRI hazard prefix (AVLN, HRCN, WFIR, …). Join key. (unit: code)
hazard_name	string	Hazard family display name.
hazard_period_of_record	string	Documented period of record behind this hazard's frequency model (e.g. '1994-2023 (30 years)').
events_per_year	float	Hazard EVNTS / period_years — comparable across hazards with different record lengths. (unit: events/year)
annualized_frequency	float	FEMA annualized frequency (AFREQ) for the hazard in this county. (unit: 1/year)
exposed_population	float	Population exposed to the hazard (EXPP). (unit: people)
exposed_buildings	float	Buildings exposed to the hazard (EXPB). (unit: count)
exposed_area_sqkm	float	Area exposed to the hazard (EXP_AREA). (unit: km2)
eal_total_usd	float	Hazard expected annual loss, total (EALT), USD. (unit: USD)
eal_buildings_usd	float	Hazard EAL, buildings component (EALB), USD. Null where the hazard has no building component by design (e.g. drought). (unit: USD)
eal_population_usd	float	Hazard EAL, population component (EALP), USD. Null where not applicable by design. (unit: USD)
eal_agriculture_usd	float	Hazard EAL, agriculture component (EALA), USD. Null where not applicable by design. (unit: USD)
eal_share_of_county_total	float	This hazard's EALT / the county's total EAL (EAL_VALT). Null when the county EAL is null or zero. (unit: share)
hazard_rank_in_county	float	Rank of this hazard's EALT within its county (1 = largest loss driver); ties share the lower rank by code order; null when EALT is null. (unit: rank)
risk_score	float	FEMA hazard risk index score: national percentile 0–100 of the risk value. (unit: percentile)
risk_rating	string	FEMA categorical rating: Very High … Very Low, plus 'No Rating' / 'Not Applicable' / 'Insufficient Data'.
risk_rating_ordinal	float	Rating mapped to 1 (Very Low) … 5 (Very High); null for non-rated categories. (unit: ordinal)
risk_value	float	FEMA hazard risk index value (the scored quantity).
county_risk_score	float	FEMA composite National Risk Index score (0–100 national percentile), repeated per row. (unit: percentile)
county_risk_rating	string	FEMA composite rating, repeated per row.
county_eal_total_usd	float	County total expected annual loss (EAL_VALT), USD, repeated per row. (unit: USD)
county_eal_per_capita_usd	float	County EAL / population — comparable across counties of different sizes. (unit: USD/person)
county_eal_share_of_building_value_pct	float	100 x county building EAL / total building value: the expected yearly share of the built stock lost. (unit: percent)
county_dominant_hazard_code	string	Hazard code with the largest EALT in the county (ties -> alphabetical code). (unit: code)
county_dominant_hazard_name	string	Display name of the dominant hazard.
county_dominant_hazard_eal_share	float	Dominant hazard's EALT / county total EAL. (unit: share)
county_n_very_high_hazards	integer	Count of hazards rated Very High in the county. (unit: count)
multi_hazard_hotspot	boolean	True when >= 2 hazards are rated Very High — the compound-risk set. (unit: bool)
sovi_score	float	FEMA social-vulnerability score. (unit: score)
sovi_rating	string	FEMA social-vulnerability rating.
resl_score	float	FEMA community-resilience score. (unit: score)
resl_rating	string	FEMA community-resilience rating.
resl_value	float	FEMA community-resilience value.
source_url	string	Per-row provenance: the exact FEMA bulk-download URL. (unit: url)
row_hash	string	SHA-256 (16 hex) over the row's content fields; identical input yields an identical hash, so a re-run on an unchanged NRI release is a no-op. (unit: hash)
