About Natural Disaster Risk in Chickasaw County, Mississippi

Chickasaw's Risk: Below Average

Chickasaw County scores 43.92 on the composite risk scale, placing it in the Relatively Low category and below Mississippi's average of 50.94. This means residents face fewer natural disaster threats than typical Americans, though certain hazards still warrant attention.

Safer Than Most Mississippi Counties

Among Mississippi's 82 counties, Chickasaw ranks in the lower half for overall disaster risk. The county's 43.92 score sits comfortably below the state average, making it one of the safer areas in Mississippi for natural hazard exposure.

Compared to Adjacent Counties

Chickasaw's risk profile aligns with nearby Clay County (42.53), though it faces slightly higher tornado risk than Clarke County (66.00 vs 66.00). Coahoma County to the north presents notably higher overall risk at 62.50, driven by exceptional earthquake exposure.
