Risk Overview
Overall natural disaster risk in Spencer County is very low, with a National Risk Index score of 13.3 out of 100 — placing it in the 13th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in tornado (violently rotating columns of air capable of catastrophic local damage) at Low risk — $3M in expected annual loss and about 0.13 events per year; strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Low risk — $892K in expected annual loss and about 6.60 events per year; and landslide (downhill movement of rock, soil, and debris on unstable slopes) at Very Low risk — $1K in expected annual loss and about 0.42 events per year. Across all hazards, FEMA estimates $9M in expected annual loss for a population of 19K.
Beyond physical exposure, Spencer County has a very low social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Spencer County has received 29 federal disaster declarations since 1974, including 15 for severe storm events and 4 for tornado events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
