Quick LinksNational life expectancy estimates are calculated using period (current) life tables. Life tables are used to measure mortality, survivorship, and the life expectancy of a population at varying ages.
Period life tables estimate how many more years a group of people who are currently at a particular age – any age from birth to 100 or more – can expect to live if the mortality patterns in a given year remain the same over the rest of their lives. Life tables can also be used to compare how life expectancy has improved or declined over time.
National-level life tables are released annually, as well as every 10 years (decennially) around the U.S. population census.
