Interpretation
Demographics Interpretation
The data paints a clear, if unfortunate, portrait of the most vulnerable hiker: a young, overconfident, solo urban man, likely underestimating the trail while overestimating his own preparation, who statistically should have brought a friend, left his ego at the trailhead, and maybe just gone for a brisk walk in the city park instead.
