Risk Overview
FEMA's National Risk Index rates Lamar County at very low composite risk, with a National Risk Index score of 7.8 out of 100 — placing it in the 8th 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 hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Low risk — $324K in expected annual loss and about 0.07 events per year; drought (extended dry periods that stress water supplies and agriculture) at Low risk — $158K in expected annual loss and about 52.20 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Very Low risk — $144K in expected annual loss and about 0.00 events per year. Across all hazards, FEMA estimates $4M in expected annual loss for a population of 18K.
Beyond physical exposure, Lamar County has a medium 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). Both measures sit toward the lower end, indicating relatively modest population sensitivity.
The federal record bears this out: Lamar County has received 19 federal disaster declarations since 1977, including 6 for hurricane events and 5 for severe storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 159 Georgia counties, Lamar County ranks #141 for overall natural disaster risk.
