How the figures are counted: a declaration is counted once per state and incident type by its FEMA disaster number, even when it designates many areas; shares and the yearly average are calculated by this site from those counts.
Worked example: Missouri, Severe Storm: 48 declarations over 62 years (1965–2026) = 0.77 per year on average.
