Risk Overview

About Natural Disaster Risk in Darlington County, South Carolina

Darlington faces slightly above-average national risk

Darlington County's composite risk score of 72.26 places it in the Relatively Low category but slightly above the national average, reflecting moderate exposure to natural disasters. The county scores elevated on tornado (84.35), hurricane (87.86), and earthquake (86.10), while flood (64.22) and wildfire (73.95) remain more controlled. This profile positions Darlington as an average-to-above-average risk county within the national context.

Darlington ranks slightly above state average

Darlington County's composite score of 72.26 exceeds South Carolina's 70.75 state average, placing it among the state's moderate-risk counties despite its Relatively Low designation. Tornado (84.35), hurricane (87.86), and earthquake (86.10) exposures particularly elevate Darlington's profile relative to lower-risk inland counties. This positioning reflects Darlington's combined exposure to spring severe weather and Atlantic hurricane tracks.

Darlington comparable in risk to Chesterfield

Darlington County's 72.26 score closely aligns with Chesterfield County (73.98), positioning both as the region's moderate-risk counties with similar hazard exposure. Both significantly exceed Chester County (43.16) in overall risk while remaining well below coastal Charleston County (98.63). This similarity suggests shared disaster preparedness concerns across the regional corridor.

Tornadoes and hurricanes present primary threats

Darlington County's highest risks stem from tornado (84.35), hurricane (87.86), and earthquake (86.10) hazards, all scoring significantly above typical county levels and creating compound severe weather exposure. Wildfire risk (73.95) remains meaningful, while flood risk (64.22) ranks moderate. The combination of spring tornado season and Atlantic hurricane tracks creates distinct seasonal vulnerability periods.

Wind coverage and earthquake insurance recommended

Darlington County homeowners should maintain comprehensive wind and hail coverage in their homeowners policies given tornado (84.35) and hurricane (87.86) exposures—ensure deductibles reflect realistic repair costs. Earthquake insurance merits consideration given the elevated 86.10 score, and reviewing flood exposure in low-lying areas remains prudent despite moderate flood risk. Annual policy reviews ensure your coverage keeps pace with changing climate conditions and property values.

The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Darlington County higher risk than average?
Darlington County's composite risk score of 72th percentile is above the South Carolina state average of 71th percentile.
