Content:  807 climbers summited Mount Everest in 2018, including 563 on the Nepal side and 240 from the Chinese Tibet side.

Various records were broken, including a summit by double-amputee Hari Budha Magar, who undertook his climb after winning a court case in the Nepali Supreme Court. There were no major disasters, but seven climbers died in various situations including several sherpas as well as international climbers.

Content:  Everest's first known summiting occurred by 1953, and interest by climbers increased. Despite the effort and attention poured into expeditions, only about 200 people had summitted by 1987. Everest remained a difficult climb for decades, even for serious attempts by professional climbers and large national expeditions, which were the norm until the commercial era began in the 1990s. By March 2012, Everest had been climbed 5,656 times with 223 deaths. Although lower mountains have longer or steeper climbs, Everest is so high the jet stream can hit it. Climbers can be faced with winds beyond 200 mph when the weather shifts. At certain times of the year the jet stream shifts north, providing periods of relative calm at the mountain. Other dangers include blizzards and avalanches. By 2013, The Himalayan Database recorded 6,871 summits by 4,042 different people.
