Abstract Since the winter of 1950–1951, 1084 individuals perished in snow avalanches in the United States. In this study, we analyze the ages of those killed (n = 900) by applying non-parametric methods to annual median ages and for age groups and primary activity groups. Change point detection results indicate a significant change in 1990 in the median age of avalanche fatalities. Significant positive trends exist for both the 1950 to 2018 and 1990 to 2018 median age of victims. The median age of victims from 1950 to 1989 is 27 and is 33 from 1990 to 2018. Since 1990, the 30–39 and 40–49 age groups are the only age categories to exhibit a positive trend in the number of fatalities. There is no significant difference in median ages between snowmobilers and other categories. These results can be used to enhance avalanche education and forecasting efforts in the United States. Management implications Using the best available dataset of avalanche fatalities in the United States, we found that the age of avalanche victims increased from 1950 to 2018. Though avalanche educators should still reach out to students of all ages, our results suggest that programs that target recreationalists over 30 years of age could have a better chance of reducing the number of people killed in avalanches. In addition, avalanche warning services should use a wide range of methods to disseminate avalanche safety information, and include products that target older and, potentially more experienced, users.
