About this state

FEMA disaster context for South Carolina

South Carolina has 1,175 county-level FEMA disaster declarations spread across 46 counties. The most common declaration type is hurricane. Across all counties, FEMA datasets track $2.3B in combined public and individual assistance obligations.

The counties with the heaviest disaster history are Horry County (34 declarations), Orangeburg County (31), and Berkeley County (30). Each county page breaks down the timeline, hazard mix, spending categories, and flood insurance signals for that specific area.

Declaration counts reflect how often FEMA formally declared a disaster or emergency affecting a county — not the total number of natural events. A single hurricane can generate declarations across dozens of counties and multiple states. The county pages linked above show the per-county detail behind these state-level totals.
