Risk Overview
Overall natural disaster risk in Antrim County is very low, with a National Risk Index score of 25.8 out of 100 — placing it in the 26th 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.
Most of Antrim County's expected losses come from cold wave (prolonged spells of dangerously low temperatures) at Medium risk — $3M in expected annual loss and about 1.26 events per year; landslide (downhill movement of rock, soil, and debris on unstable slopes) at Low risk — $8K in expected annual loss and about 0.20 events per year; and lightning (electrical discharges from storms that ignite fires and cause casualties) at Low risk — $210K in expected annual loss and about 24.66 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 23K.
Beyond physical exposure, Antrim County has a 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 federal record bears this out: Antrim County has received 7 federal disaster declarations since 1977, including 2 for biological events and 1 for flood events. The most recent was Severe Storms, Tornadoes, and Flooding (flood), declared in June 2026.
Among 83 Michigan counties, Antrim County ranks #60 for overall natural disaster risk.
