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: Iowa, Flood: 30 declarations over 71 years (1953–2023) = 0.42 per year on average.
