Dynamics of human mortality

Entire human mortality curves are shown here to be compatible with this single distribution given the assumption that individuals vary only with respect to the interactive risk parameter (k). Historical Swedish cohort data are modelled here exclusively through changes in k values, clustered increasingly toward the higher end of their range, while redundancy values are held constant. This pattern is compatible with the hypothesis that historical changes in human mortality may be explained purely in terms of interactive risks and without changes in the underlying pattern or rate of ageing.
