Bears are some of North America’s most recognizable wildlife, symbolizing both the untamed wilderness and, occasionally, danger. While these animals are incredible to watch from a safe distance, their interactions with humans can sometimes have tragic outcomes.

Bears of North America

North America is home to three species of bears, each with unique traits and risks:

• Black Bear (Ursus americanus)
  • Range: Found across much of Canada, the United States, and parts of Mexico.
  • Population: Around 800,000.
  • Traits: Shy by nature but can be dangerous when food is involved or when defending cubs.
• Grizzly Bear (Ursus arctos horribilis)
  • Range: Predominantly in Alaska, western Canada, and parts of the U.S.
  • Population: Estimated 55,000, with over half in Alaska.
  • Traits: Larger and more aggressive than black bears, known for their strength and territorial behavior.
• Polar Bear (Ursus maritimus)
  • Range: Arctic regions of Canada, Alaska, Greenland, and Russia.
  • Population: Between 22,000 and 31,000 worldwide.
  • Traits: Specialized hunters of seals and the most likely to view humans as prey.

Understanding these species is essential to making sense of their behavior and their interactions with humans. Now, let’s take a closer look at what maps can tell us about fatal bear attacks.

The historical map by Reddit user bfskht documents fatal bear attacks from 1784 to 2018, showing clear patterns of where humans and bears are most likely to collide.

An animated map adds another layer of insight, revealing yearly trends in fatal attacks and the roles of different bear species:

• Grizzly bears (46% of attacks): Most active in September and October.
• Black bears (40% of attacks): Peaks in May and August.
• Polar bears (11% of attacks): Spikes in July and November.

The data also shows that at least two fatal bear attacks occur annually, with the largest number happening in summer and fall.

Which Bear Is the Most Dangerous?

Grizzly bears are often considered the most dangerous due to their size, strength, and aggression. However, black bears have been involved in a significant number of fatal attacks, especially when food is at stake. Polar bears, though less encountered, pose a high risk in their Arctic habitat, where resources are scarce.

How to Stay Safe in Bear Country

Here are some tips to minimize your risk of a bear encounter:

• Keep food secure: Use bear-proof containers and store food away from your campsite.
• Make noise: Talk or clap to avoid surprising a bear.
• Travel in groups: Groups are less likely to be targeted by bears.

If you encounter a bear:

• Black bear: Make yourself look big, make noise, and fight back if attacked.
• Grizzly bear: Back away slowly and play dead if attacked.
• Polar bear: Avoid at all costs; carry bear spray if traveling in Arctic regions.
