Dynamics of life expectancy and life span equality
As people live longer, ages at death are becoming more similar.
This dual advance over the last two centuries, a central aim of
public health policies, is a major achievement of modern civilization.
Some recent exceptions to the joint rise of life expectancy and life
span equality, however, make it difficult to determine the underlying
causes of this relationship. Here, we develop a unifying
framework to study life expectancy and life span equality over time,
relying on concepts about the pace and shape of aging.
