Climber fatality from attempts through 2006:
Suicide estimate from NIH:
Actually, Everest is considered as on the easier side for an eight-thousander . Annapurna got %38 (2007 figures)  and K2 got %25 .
For some interesting discussion on Everest fatalities, try this one . "No shortcuts to the top" by Ed Viesturs and the well known "Into thin air" by Jon Krakauer are two good books on the subject, if you want to read more.
Yup, I've read that. The account by the reporter from Outdoors (?) was extremely graphic in detail (but disputed by others in the party). Sad all around, but through those deaths came better regulation which has led to a 1:7 ration of attempts/deaths vs. 1:4 in previous years.
This is very good visualization. It brings out the fact that number of summits have exponentially increased by number of death only linearly and with very slight slop. This means w have gotten exponentially better at summiting over time.
