County Rankings
Counties in South Dakota ranked by risk. Click column headers to sort. Click a county to see its departments.
NRI Rating is from FEMA's National Risk Index, which measures community risk across 18 natural hazards using expected annual losses, social vulnerability, and community resilience. Life-Safety Loss uses FEMA's Value of Statistical Life ($13.7M per expected fatality) to estimate annual risk to human life.
Department and station counts are derived from boundaries self-reported through NERIS Public and may not reflect current service areas. Risk metrics are computed from census tract data and are not affected by boundary accuracy. See full methodology.
