Risk Overview
Jackson County carries a low composite natural disaster risk, with a National Risk Index score of 67.8 out of 100 — placing it in the 68th national percentile and below the national average for natural-disaster risk. 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 ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Very High risk — $1M in expected annual loss and about 1.14 events per year; earthquake (ground shaking from sudden movement along geologic faults) at Medium risk — $4M in expected annual loss and about 0.01 events per year; and tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $4M in expected annual loss and about 0.50 events per year. Across all hazards, FEMA estimates $17M in expected annual loss for a population of 17K.
Beyond physical exposure, Jackson County has a very 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: Jackson County has received 35 federal disaster declarations since 1968, including 17 for severe storm events and 5 for flood events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 75 Arkansas counties, Jackson County ranks #26 for overall natural disaster risk.
