Figure 3-3

Mortality curves implied by the compression-rectangularization hypothesis. Note: Changes in these three curves are interrelated: over time the hazard function falls more rapidly at younger than older ages. the area under the survival function grows larger as the curve becomes more rectangular, and the density function shifts to the right and becomes more compressed. The distribution may or may not be truncated at some maximum age. Likewise, the dashed curves may or may not represent ultimate mortality limits.
