Methodology for report on most dangerous national parks during winter
Mortality data was gathered from the U.S. National Park Service from 2007 to 2023. The incidents were categorized according to date, with any incidents between Nov. 1 and Feb. 28 for each year being considered or Feb. 29 if it was a leap year. Average visitation numbers were then gathered for the period covered. The parks were then ranked by the highest number of winter deaths per 10 million visitors. Any parks with less than 10 million total visitors between 2007 and 2023 were excluded. Homicide and suicide deaths were also removed from the statistics for winter deaths.
