Notes on Life Expectancy

• LE is a mean, so it is skewed by infant mortality, young male deaths at the low end and the group of really long lifers at the other end. Like income, LE (mean) isn't useful for individuals. A much better indicator is median age at death. Which is the age that most people die at.
