Patterns of diversity in age at death are examined using e†, a dispersion measure that also equals the average expected lifetime lost at death. We apply two methods for decomposing differences in e†. The first method estimates the contributions of average levels of mortality and mortality...

We estimate a Cox proportional hazards model where one of the covariates measures the level of a subject´s cognitive functioning by grading the total score obtained by the subject on the items of a questionnaire. A case study is presented where the sample includes partial respondents, who did...

There is one unique age separating early deaths from late deaths such that averting an early death decreases life disparity, but averting a late death increases inequality in lifespans.
