Life expectancy is a projection estimating what the average age of death will be for people born today — not the average age of death of people who died this year. It is based on data regarding the health of the nation, including death rates by age, as well as estimates of the impact of current trends decades in the future.
In 2019, the average life expectancy was 78.8 years, an increase of 0.1 or 0.18% from 2018.
