Risk Overview

Perry County carries a very low composite natural disaster risk, with a National Risk Index score of 35.0 out of 100 — placing it in the 35th 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.

The county's risk is driven primarily by strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $890K in expected annual loss and about 5.84 events per year; earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $616K in expected annual loss and about 0.00 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at Low risk — $2M in expected annual loss and about 0.29 events per year. Across all hazards, FEMA estimates $11M in expected annual loss for a population of 19K.

Beyond physical exposure, Perry County has a low social vulnerability rating (how susceptible the population is to harm) and a 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: Perry County has received 22 federal disaster declarations since 1974, including 10 for severe storm events and 5 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.

Among 92 Indiana counties, Perry County ranks #58 for overall natural disaster risk.
