Everest Age, Success and Fatalities
Should older climbers be allowed to climb Everest?

Chinese authories impose an age limit on Everest North side (Tibet) of 18 to 60 years.

Previously enforcing minimum 16 years age limit, as of 2015 the Nepal goverment (Everest South side) is considering to ban climbers below the age of 18 and above the age of 75, as well as disabled climbers.

Facts

Analayzing data from 11,000 summit attempts between 1922 and 2006, Adventurestats found there is no factual increased fatality rate for climbers above 50 years of age.

  • 0-29y = 1.9%
  • 30-39y = 1.7%
  • 40-49y = 1.5%
  • 50-100y = 1.6%

Any enforcement of a maximum age would be based on ethical, political or other soft values, but not in factual measured risk.

Are older climbers less likely to reach the summit of Everest?
Facts

Based on 11,000 summit attempts there is no age-related difference in success:

  • 0-40y = 20.9%
  • 40-100y = 20.3%
CONCLUSIONS

Based on data 1922 - 2006.

ALL CLIMBERS
  • Everest has been attempted 11000 times
  • 3000 attempts have been successful (reached the summit)
  • Success rate is 29%
  • 207 climbers have died on Everest
  • Fatality rate is 2.05%
  • 54 of the summiteers died
  • Summit to Fatality rate is 1.82%
NON PORTER NATIONS (EXCLUDING CHINA, NEPAL, INDIA)
  • Everest has been attempted 7700 times
  • 1600 attempts have been successful (reached the summit)
  • Success rate is 20%
  • 104 climbers have died on Everest
  • Fatality rate is 1.34%
  • 39 of the summiteers died
  • Summit to Fatality rate is 2.52%
EVEREST AND AGE OVERALL
  • The Attempt to Fatality rate does not significantly vary with age. 0-29y = 1.9%, 30-39y = 1.7%, 40-49y = 1.5%, 50-100y = 1.6%.
  • The summit to Fatality rate does vary slightly when porters are included in statistics. Age below 40 = 1.6%, Age 40 and above = 2.3%
EVEREST AND AGE (EXCLUDING CHINA, NEPAL, INDIA)
  • Climbing porters have a higher success rate than non porters. The porters are younger than the general Everest population. Porters thus have to be excluded when further comparing age.
  • The success rate for climbers (non porter nations) does not vary with age. Climbers below 40 years have a success rate of 20.9%, Climbers 40 years and above have a success rate of 20.3%
  • The summit to Fatality rate does not vary with age. Climbers below 40 have a Summit to Fatality rate of 2.5%. Climbers 40 years and above have 2.6%
  • The Attempt to Fatality rate does not vary with age. Climbers below 40 have an Attempt to Fatality rate of 1.4%. Climbers 40 years and above have an Attempt to Fatality rate of 1.3%
