Definition of actuarial. 1  1 : of or relating to actuaries. 2  2 : relating to statistical calculation especially of life expectancy.
DEFINITION of 'Actuarial Life Table'. A table or spreadsheet that shows the probability of a person at a certain age dying before his or her next birthday. These statistics calculate the remaining life expectancy for people at different ages and the probability of surviving a particular year of age. Because men and women have differing mortality rates, an actuarial life table is computed for separately for men and women.
