Table 3. Death rates (overall and on descent from summit), numbers of deaths, and numbers of climbers at risk (boldfaced).

	Time period
Rate	1990–1994	1995–1999	2000–2004	2005–2009	2010–2014	2015–2019
Overall death rate	0.8	2.4	1.3	1.3	1.1	0.8
Total deaths	2	12	12	17	13	10
N climbers at risk	227	499	900	1363	1154	1181
Descent death rate	0.0	6.1	1.2	1.1	1.1	0.9
Total descent deaths	0	9	4	8	8	7
N summiters	62	147	326	724	715	816

Overall death rates are for all climbers who went above base camp, and descent death rate is only for climbers descending from the summit. Numbers here reflect our primary subset of members (i.e., first-time climbers, on commercial route, in spring during non-disaster years).
