Another look at mortality crossovers.
Considerable debate still ensues on whether or not the so-called "mortality crossover," the intersection of age curves of mortality at the older ages, is artifactual or real. One school of thought argues that it is a function of misreporting of ages, greater for one population than another. The other school of thought counters that it persists apart from age misreporting and is due to selective frailty processes as age increases. An historical review of the debate is reported, after which an attempt at a balanced conclusion is offered.
