afterlifetime

plural afterlifetimes

1. businessLife expectancy measured according to a general average, rather than for any given individual.

   The most probable afterlifetime of any individual is the difference between his present age and the age at which most deaths occur, and is therefore very different from the expectation of life.

   The afterlifetime of men of the age of 30 is 33 years, by the English Life Table (No. 1); 33 years is not the precise time probably that any one of that age will live, but the average time that a number of men of that age will live, taken one with another. At birth lifetime, and afterlifetime are one and the same thing.
