Federal Emergency Management Agency (FEMA)

FEMA disaster declarations by designated area

Every FEMA disaster declaration summary from OpenFEMA (DisasterDeclarationsSummaries v2, https://www.fema.gov/api/open/v2), one row per declaration x designated area. Each row carries the declaration type (DR major disaster, EM emergency, FM fire management, FP fire suppression), incident type, declaration and incident dates, fiscal year declared, which assistance programs were authorized (Individuals and Households, Individual Assistance, Public Assistance, Hazard Mitigation), state, county FIPS and FEMA region. Method: keyless GET with OData paging ($top=1000, deterministic $orderby=disasterNumber,designatedArea); volatile API-internal fields (id, hash, lastRefresh) are excluded so snapshots only change when the data changes. Units: none (categorical + dates); program flags are booleans. Caveats: ongoing incidents have null end/closeout dates until FEMA closes them; FEMA can amend historical records; declaration_title is free-text incident names. Coverage: U.S. states, territories and tribal nations, 1953 to present, per designated area. Provenance: FEMA OpenFEMA API - citation required, see license. Primary key: (fema_declaration_string, designated_area). Join keys: state_code, declaration_year. Cadence: refreshed daily; a new snapshot appears only when the data changes. Sample use: count declarations by state_code and declaration_year for disaster frequency trends; filter incident_type for hazard-specific series.
