Modal age at death  (MODAL age at death)


The median length of life1 (cf. 140-6) sometimes called the probable length of life1 is the age at which half the original cohort (116-2) of births have died. After infancy the distribution of deaths by age in the life table (431-1) will usually have a mode (140-8) and the age corresponding to it is called the modal age at death2, or sometimes the normal age at death2. It may be of interest as an indicator of human longevity3 or the length of life3 corresponding more closely to the sense in which the term is used in everyday language than either the mean (433-4) or the probable length of life. The term life span4 is sometimes used for the maximum possible length of human life.
