Spring 2011 season
203 expeditions, of which 123 put someone on the summit. 751 summits (378 by members, 373 by hired staff) and 12 deaths, among 827 members and 499 hired staff recorded.
Summits count member records: someone who summited twice on one expedition counts once, someone on two expeditions in the season counts twice. Claimed (unrecognised) ascents are excluded and disputed ones included, as in the database's own statistics. Hired staff are only recorded when they went above base camp.
