What is the correlation of life expectancy and mortality?

The most commonly used indicator for analyzing mortality is life expectancy at birth, i.e. the mean number of years that a person can expect to live at birth subjected to current mortality conditions throughout the rest of their lives. Life expectancy originates from demography but is an often-used summary measure of mortality also in epidemiology and public health in general.
