Current life table  (CURRENT life table)


A current life table1 (cf. 153-2; 431-1) is one in which the mortality rates used relate to a specified time interval and the cohort (116-2) is therefore fictitious (cf. 153-3). A generation life table2, or cohort life table2 on the other hand, traces the experience of an actual cohort and the mortality rates contained therein are then spread over a prolonged period, usually about 100 years. A mortality surface3 is drawn when age-specific death rates (401-7) are plotted against age and time period simultaneously in a three-dimensional diagram.
