Risk Overview
FEMA's National Risk Index rates Stonewall County at very low composite risk, with a National Risk Index score of 3.8 out of 100 — placing it in the 4th 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 Stonewall County's expected losses come from drought (extended dry periods that stress water supplies and agriculture) at High risk — $1M in expected annual loss and about 83.97 events per year; wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $93K in expected annual loss and about 0.00 events per year; and hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $166K in expected annual loss and about 5.02 events per year. Across all hazards, FEMA estimates $2M in expected annual loss for a population of 1K.
Beyond physical exposure, Stonewall County has a 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 county's disaster history tells the same story: Stonewall County has received 16 federal disaster declarations since 1993, including 6 for fire events and 3 for hurricane events. The most recent was Severe Winter Storms (severe ice storm), declared in February 2021.
Among 254 Texas counties, Stonewall County ranks #236 for overall natural disaster risk.
