The term “life expectancy” refers to the number of years a person can expect to live. By definition, life expectancy is based on an estimate of the average age that members of a particular population group will be when they die.
Life Expectancy is calculated using the Mortality Ratios. The values are for the mid-point of each age range. This data provides population life expectancy. Care should be taken when there is any prior selection, for example directly through medical underwriting or indirectly through income.
