Sur-vīv'or-ship, n.
n. 1. The state of being a survivor, or of outliving another.

Chance of survivorship, the chance that one individual, of a given age, has of surviving another of a given age; thus, by the Carlisle table, the chances of survivorship for two persons, aged 25 and 65, are 80 and 11 respectively, or about 8 to 1 that the elder will die first.
