Risk Overview
Overall natural disaster risk in Oldham County is low, with a National Risk Index score of 56.0 out of 100 — placing it in the 56th national percentile and below the national average for natural-disaster risk. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at High risk — $3M in expected annual loss and about 6.14 events per year; tornado (violently rotating columns of air capable of catastrophic local damage) at Medium risk — $8M in expected annual loss and about 0.14 events per year; and lightning (electrical discharges from storms that ignite fires and cause casualties) at Medium risk — $627K in expected annual loss and about 51.47 events per year. Across all hazards, FEMA estimates $29M in expected annual loss for a population of 68K.
Beyond physical exposure, Oldham County has a very low social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Oldham County has received 18 federal disaster declarations since 1974, including 9 for severe storm events and 2 for biological events. The most recent was Severe Winter Storm (winter storm), declared in January 2026.
Among 120 Kentucky counties, Oldham County ranks #36 for overall natural disaster risk.
