Risk Overview
Overall natural disaster risk in Anson County is low, with a National Risk Index score of 50.0 out of 100 — placing it in the 50th 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.
Risk here concentrates in hurricane (tropical cyclones bringing extreme wind, rain, and storm surge) at Medium risk — $2M in expected annual loss and about 0.17 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $188K in expected annual loss and about 1.54 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $653K in expected annual loss and about 2.93 events per year. Across all hazards, FEMA estimates $10M in expected annual loss for a population of 22K.
Beyond physical exposure, Anson 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: Anson County has received 22 federal disaster declarations since 1977, including 13 for hurricane events and 2 for tropical storm events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 100 North Carolina counties, Anson County ranks #76 for overall natural disaster risk.
