Mount Everest Summit Statistics: Annual Climbers 1953-2023

Mount Everest summits have evolved from rare feats to seasonal industry. The data reveals distinct eras:

Historical Eras

Pioneering Era (1953-1970s)

First summit: Hillary & Norgay (1953). Few attempts, national expeditions, no commercial guiding. Annual summits: 0-58.

Early Commercial Era (1980s-1990s)

Guided expeditions emerge. 1990: 610 summits (first >600). 1996: 803 summits — deadliest season (15 deaths, chronicled in Into Thin Air).

Modern Commercial Era (2000s-2010s)

Multiple operators, fixed ropes, supplemental oxygen standard. 2007: first >400 since 1996. 2013: 658. 2018: record 807. Crowding, "traffic jams" at Hillary Step.

COVID Disruption (2020-2021)

Zero summits both years — Nepal and China closed permits. First zero-summit years since 1974.

Post-COVID (2022-2023)

• 2022: 408 summits (Nepal only; China still closed)
• 2023: ~600+ estimated (Nepal reopened; China partially)

Key Trends

• Success rates: 60-70% of permit holders summit (weather, health, logistics)
• Death rate: ~1% of climbers above base camp (150+ total since 1922)
• Sherpa ratio: 1:1 or 2:1 (climber:Sherpa) on commercial expeditions
• Cost: $35,000-$100,000+ (permits $11,000 Nepal / $9,950 Tibet)
• Season: April-May (pre-monsoon); rare post-monsoon attempts

Data Limitations

Official statistics vary: Nepal Tourism Department, China Tibet Mountaineering Association, Himalayan Database (Elizabeth Hawley's legacy). "Summit" definitions differ (true summit vs. fore-summit). 2023 data preliminary.

Everest has become a high-altitude assembly line—but each number represents a human at the edge of physiology, supported by Sherpa expertise, chasing a 29,032-foot line on a map.
