FEMA publishes a risk score for counties and none for states, so none is shown here. Each county's score is on its own page.

Where these numbers come from

Each reading is the published figure, not an estimate. A dash means the source did not publish one, or published one too uncertain to print.

• State figures: U.S. Census Bureau, American Community Survey 20245-year estimates, the state's own row (tables B25064, B19013, B25077, B25103, B01003, DP03).
• County figures: the same survey, each county's own row, as on every county page.
• Price level: Bureau of Economic Analysis, regional price parities, 2024, all items, state-level.
• Health: County Health Rankings & Roadmaps 2025, University of Wisconsin Population Health Institute, the state's own row. Poor or fair health is a modeled estimate from CDC survey data. The other three are counted or calculated.
• Natural hazards: FEMA National Risk Index, December 2025, state table, expected annual loss. This product uses FEMA data but is not endorsed by FEMA.
• Air quality has no state figure: the EPA publishes it by county and metro area only.
