Risk Overview
Overall natural disaster risk in Jackson Parish is very low, with a National Risk Index score of 26.2 out of 100 — placing it in the 26th 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.
Most of Jackson Parish's expected losses come from ice storm (freezing rain that coats surfaces in heavy, damaging ice) at High risk — $401K in expected annual loss and about 1.37 events per year; heat wave (prolonged periods of extreme heat that threaten health and infrastructure) at Low risk — $616K in expected annual loss and about 20.89 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $586K in expected annual loss and about 4.27 events per year. Across all hazards, FEMA estimates $6M in expected annual loss for a population of 15K.
Beyond physical exposure, Jackson Parish 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.
The federal record bears this out: Jackson Parish has received 27 federal disaster declarations since 1989, including 16 for hurricane events and 2 for winter storm events. The most recent was Severe Winter Storm (winter storm), declared in February 2026.
Among 64 Louisiana counties, Jackson Parish ranks #57 for overall natural disaster risk.
