As of 2012, approximately 200 people have died attempting to climb Mount Everest, out of about 4,000 climbers. About 60 percent of those deaths resulted from falling or from an avalanche, but some people also died from exposure, exhaustion, heart attack and altitude sickness.
In 1996, a record 19 people died on Mount Everest. Often, it is not only the people who are attempting the climb for the first time who die. Sometimes, it is the Sherpas who provide assistance for the climbers. Mostly the rich make this climb, since just the permit to climb cost $25,000 in 2012.
