Risk Overview
Allen County carries a very low composite natural disaster risk, with a National Risk Index score of 33.3 out of 100 — placing it in the 33rd 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 hail (ice stones from severe thunderstorms that damage property and crops) at Medium risk — $967K in expected annual loss and about 3.22 events per year; earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $946K in expected annual loss and about 0.00 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $798K in expected annual loss and about 6.22 events per year. Across all hazards, FEMA estimates $9M in expected annual loss for a population of 21K.
Beyond physical exposure, Allen County has a high social vulnerability rating (how susceptible the population is to harm) and a low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
History supports the rating: Allen County has received 22 federal disaster declarations since 1969, including 10 for severe storm events and 3 for snowstorm events. The most recent was Severe Winter Storm (winter storm), declared in May 2026.
Among 120 Kentucky counties, Allen County ranks #75 for overall natural disaster risk.
