To learn more about this topic, start your googling with these keywords:
- Life Expectancy At Birth: The average number of years a newborn in a particular group could expect to live.
- Life Expectancy After Babyhood: The average number of years a member of a particular group could expect to live given that they had survived their first year.
- Maximum Life Expectancy: The age at which the oldest known member of a particular group died.
- Mortality Rate: The frequency of occurrence of death within a particular group during a particular time period.
- Life Table: A table that shows the number of individuals within a group that survive from one year to the next until they are all dead.
- Survivorship Curve: A plot of the data in a particular life table that shows the years on the x-axis and the number or percent of survivors on the y-axis.
