Risk Overview

About Natural Disaster Risk in Perry County, Ohio

Perry County enjoys excellent low-risk status

Perry County's composite risk score of 25.99 earns a "Very Low" rating and falls well below the U.S. average, placing it among safer American counties. Residents benefit from substantially lower natural disaster exposure compared to most U.S. communities.

Among Ohio's safest counties

Perry County's 25.99 score significantly undercuts Ohio's 55.03 state average, ranking it among the state's most secure areas. The county's balanced, low profile across all hazard types reinforces this safety advantage.

Safest in its peer group

Perry County (25.99) is one of the safest counties in its region, comparable to Morgan County (18.23) and Morrow County (24.40), and substantially safer than Muskingum County (70.93). This makes it a genuinely low-risk location within southeastern Ohio.

Flood risk tops a well-balanced profile

Perry County's flood risk of 47.04 is its highest hazard score, reflecting the county's small waterways and hilly terrain, though it remains below state average. All other hazards—tornado, earthquake, wildfire, and hurricane—score below 37, creating an exceptionally manageable disaster risk picture.

Basic homeowners coverage sufficient

Perry County residents can confidently rely on standard homeowners insurance without specialized add-ons given the county's very low overall risk profile. Annual policy reviews to confirm coverage limits remain good practice, but the county's low flood and tornado scores mean specialized riders are typically unnecessary.

Risk Verdict

Compared to the nation's 3,144 counties, Perry County ranks at the 26th percentile for natural disaster risk — toward the safer end of the spectrum. Being ranked at the 26th percentile nationally is an advantage for Perry County — it means fewer statistically likely events, though basic readiness ensures households are covered when exceptions occur.

Hazard Breakdown

Flood risk is Perry County's dominant natural hazard, ranked at the 47th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 36th percentile nationally. Additional tracked hazards include tornado (32th percentile), hurricane (19th percentile), wildfire (18th percentile).

Preparedness Context

At the 47th percentile nationally for flood risk, Perry County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. The county's second-ranked hazard, earthquake at the 36th percentile nationally, means Perry County residents face compounding risks from multiple natural hazard types during peak seasons. A tested family preparedness plan specific to Perry County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

At 29.0 points below the Ohio state average, Perry County is among the lower-risk counties in the state for natural disaster exposure.
