SUMMARY:Cause-Decomposition of the Change Over Time in the Model Age at Dea
 th
DESCRIPTION:LecturerVladimir Canudas-Romo\,Assistant Professor\, John Hopki
 ns Bloomberg School of Public Health.SummaryThe great shift in causes of m
 ortality and morbidity that occurred in the developed world predominantly 
 during the twentieth century is recognized in the framework of the demogra
 phic and epidemiologic transitions. Today’s industrialized countries hav
 e largely progressed through both transitions\, as observed in the uninter
 rupted long historical rise in life expectancy at birth. This paper discus
 ses the methodology to study the cause-contribution of specific causes of 
 death to the change in measures of longevity: The mean and modal ages at d
 eath. Methods to assess the cause\, decomposition of the change in life ex
 pectancy\, or mean age at death\, are widely used by demographers.Less att
 ention has been put to study methods of cause-contribution to the change i
 n modal age at death\, or age with the highest probability of dying. The m
 ain aim of this paper is to present a new proposal of cause-decomposition 
 to the change in modal age at death. This decomposition is based on the re
 cent finding that for the modal age at death to change to older ages it is
  required that the decline in mortality occurs at ages older than the moda
 l age at death. The method follows two simple steps: (i) to identify modal
  ages at two given years M(t1) and M(t2)\, foryears t1 and t2 respectively
 \; (ii) For each year t1 and t2 the cause of death distribution after the 
 modal ages is used to apply the statistical calculations of composition an
 alysis of causes of death. This method allows studying the cause of death 
 change that went along the decline in death rates and which triggered the 
 increase in the modal age at death.
