In ecology/demography, 'survivorship' straightforwardly denotes the condition or proportion of survivors, directly derived from 'survive'/'survivor' plus the abstract noun suffix '-ship'.

Etymology

Survivorship comes from super- 'over' and vivere 'to live', the same root as survive. So, in biology or population studies survivorship is the pattern of how many individuals stay alive at different ages.
