Abstract
The generation life table is a record of past experience, tracing a cohort of lives from birth to the death of the last survivor. The record shows the number surviving to successive ages, the number dying within successive age intervals, the mortality rate (the ratio of deaths within a year of age to the number alive at its beginning), and the average years lived by the individual lives after any attained age. The generation life table is distinguished from the current life table derived from mortality rates according to age observed during a short calendar period among the many generations then in existence. In the multiple decrement table, the column of the living traced from birth is split into components on the basis of newly acquired characteristics or changes in status. In select tables, the classification is according to both age at acquistion of a new characteristic and duration since the event. Applications to health problems include comparisons of communities, analyses by causes of death, clinical medicine, hospital studies, and morbidity analyses. Applications to population problems include studies of marriage, population growth, the labor force, and the money value of a man to his dependents.
