... determinants of expected widowhood duration at age 60 in a unified framework: (1) the degree of overlap between male and female mortality distributions, (2) the spousal age gap, and (3) the dependence of spousal mortality. Using French life tables from 1962 to 2070 and simulations based on the Gompertz law...

...S. Jay Olshansky; Bruce A. Carnes Abstract In 1825 British actuary Benjamin Gompertz made a simple but important observation that a law of geometrical progression pervades large portions of different tables of mortality for humans. The simple formula he derived describing the exponential rise...

...Ting Li; Yang Claire Yang; James J. Anderson Abstract Deviations from the Gompertz law of exponential mortality increases in late-middle and early-old age are commonly neglected in overall mortality analyses. In this study, we examined mortality increase patterns between ages 40 and 85 in 16 low...
