The Himalayan Database has updated their 2017 and overall statistics and the number are in. Himalayan expert Alan Arnette spent a few weeks digging through the archives and came up with a number of lists and trivia. Find the database here.

About the statistics, Arnette said: “The headlines include that Everest summits are growing, death rates are reducing and climbing from Tibet is getting more popular.

“Look for Everest to become more crowded, more expensive over the next five years, regardless of which side you climb, and six to eight people to lose their life each year – more on the south side due to more people climbing that side.”

Arnette goes into detail about who the Sherpa are and gives a number of interesting points, some are below. Visit his blog here for the full list of statistics.


Sherpa is the name of a people.
They mostly live in western Nepal.
They migrated from Tibet over the last several hundred years.
Sherpas climb Everest as a job to support their families.
Sherpas feel it is disrespectful to stand literally on the tippy top since that is where Miyolangsangma, the Tibetan Goddess of Mountains, lives.
Sherpa is also used as a last name.
Usually their first name is the day of the week they were born:
Nyima – Sunday
Dawa – Monday
Mingma – Tuesday
Lhakpa – Wednesday
Phurba – Thursday
Pasang – Friday
Pemba – Saturday
