Is skiing or snowboarding safer?

Winter will be here soon, so it’s time to talk about winter sports. I have kids who may become interested in snowboarding or skiing soon. As a protective parent, should I suggest the sport with the 62% lower risk of injury (skiing) or the one with a 61% lower risk of death (snowboarding)?

Skiing vs. Snowboarding? Which is more dangerous?

I think that Mpora’s math is wrong where it points out, “Snowboarders…33% less likely to be fatal,” though. Using the raw numbers in the full article, I calculated that a snowboarder being 61% less likely to suffer a fatal accident than a skier.

100% × (1 – ((snowboarder_deaths ÷ total_snowboarders) ÷ (skier_deaths ÷ total_skiers))) = reduced_risk_of_snowboarder_death

100% × (1 – ((12 ÷ (7,300,000 + 300,000)) ÷ (39 ÷ (8,250,000 + 1,500,000)))) = 61%

Or, any snowboarder who is injured is 85% less likely to be injured fatally than any skier who is injured.

100% × (1 – ((snowboarder_deaths ÷ snowboarder_injuries) ÷ (skier_deaths ÷ skier_injuries))) = reduced_risk_of_injured_snowboarder_death

100% × (1 – ((12 ÷ ((6.97 ÷ 1000) × (7,300,000 + 300,000))) ÷ (39 ÷ ((2.63 ÷ 1000) × (8,250,000 + 1,500,000))))) = 85%
