26 years of animal encounter data

The Deadliest U.S. States for Animal Encounters

Outforia analyzed CDC mortality records from 1999 to 2024 to see which states record the most animal-related deaths, and where the risk appears highest relative to population.

Most deaths

Where the most fatal animal encounters happened

This ranking shows where animal-related deaths have been recorded most often over the full 26-year period.

Takeaway: This view is useful for scale. It shows where deaths were recorded most often, but it does not account for how many people live in each state.

Per 10 million residents

Where fatal encounters are most common per person

This ranking compares deaths against population, making it easier to spot states where fatal encounters are more common per person.

Takeaway: This view is better for comparison. It shows which states stand out once population size is taken into account.

Safety tips

How to reduce your risk around wildlife

Fatal animal encounters are rare, but a few trail-ready habits can lower the risk further when hiking, camping or exploring unfamiliar areas.

Give wildlife room.On the trail, do not approach, feed or corner wild animals, even when they appear calm. Use zoom for photos and back away slowly if an animal changes its behavior.
Take stings seriously.Before heading out, people with known allergies should carry prescribed medication, avoid scented products where possible and seek urgent help after severe reactions.
Supervise dog interactions.Children should be supervised around unfamiliar dogs. Avoid reaching over fences, disturbing dogs while eating or approaching animals without the owner's permission.
Watch where you step and reach.In snake, spider or scorpion habitats, use a flashlight at night, wear suitable footwear and avoid putting hands into logs, rock gaps or hidden spaces.
Store food properly outdoors.At camp, keep food and scented items sealed and away from sleeping areas. Follow local bear, raccoon and wildlife storage rules.
Know the local risks.Check park guidance before you go. Advice can change by season, trail, weather, region and recent wildlife activity.
Methodology

How this analysis was built

Outforia reviewed CDC WONDER mortality records for deaths where the underlying cause was linked to animal-related external cause codes. The 1999 to 2020 figures come from CDC WONDER's Underlying Cause of Death table for 1999 to 2020, and the 2021 to 2024 update comes from the newer Underlying Cause of Death, 2018 to 2024, Single Race table. Only 2021 to 2024 from the newer table was added, so the overlapping years 2018 to 2020 were not counted twice.

The ICD-10 codes included were W53, W54, W55, W56, W57, W58, W59, W64, and X20 through X29. These cover broad categories such as dogs, other mammals, reptiles, marine animals, insects, spiders, snakes and other venomous animals.

States were ranked by total deaths and by deaths per 10 million residents. Rates were calculated by dividing deaths by summed annual population across the same years, then multiplying by 10,000,000. CDC suppresses exact death counts below 10, so suppressed state or category rows are labelled rather than estimated. The data is suitable for state comparisons, but not for exact species-level claims.
