Risk Overview

Sumter County carries a low composite natural disaster risk, with a National Risk Index score of 53.0 out of 100 — placing it in the 53rd 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 tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $2M in expected annual loss and about 0.86 events per year; hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $667K in expected annual loss and about 0.09 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $610K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 12K.

Beyond physical exposure, Sumter County has a very high social vulnerability rating (how susceptible the population is to harm) and a very 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.

The federal record bears this out: Sumter County has received 20 federal disaster declarations since 1973, including 10 for hurricane events and 4 for severe storm events. The most recent was Hurricane Helene (hurricane), declared in September 2024.

Among 67 Alabama counties, Sumter County ranks #42 for overall natural disaster risk.
