Hi....
Life expectancy is the average number
of years of life remaining at a given age.
Life expectancy is heavily dependent on the
criteria used to select the group. In
countries with high infant mortality rates,
the life expectancy at birth is highly
sensitive to the rate of death in the first
few years of life. In these cases, another
measure such as life expectancy at age 5 (e5)
can be used to exclude the effects of infant
mortality to reveal the effects of causes of
death other than early childhood causes..... |
