While bear attacks are statistically rare for humans, the raw numbers—from Yellowstone's grizzlies to Romania's recent surge—reveal a gripping and sometimes deadly intersection of wilderness and human activity.
Key Takeaways

- From 2000 to 2019, Yellowstone National Park recorded 44 bear-human conflicts resulting in injury, averaging 2.2 per year, primarily black bears
- In Alaska from 2008 to 2018, there were 23 grizzly bear attacks on humans, with 4 fatalities
- From 1784-2022, 68 fatal black bear attacks in North America
- Grizzly/brown bear fatalities in North America: 113 since 1784
- Polar bear fatal attacks worldwide: 73 from 1870-2014, 20 fatal

- Grizzly maulings in Alaska: 96 non-fatal 2000-2020
- Yellowstone: 37 non-fatal bear injuries 2000-2020
- North America grizzly attacks: 80% in Alaska/Yellowstone
