Life expectancy at birth by country
Compare life expectancy, rankings and historical trends across countries.
What it measures
Life expectancy at birth is the average number of years a newborn would live if the age-specific mortality rates observed in the indicator year remained constant throughout life. It is a period life-table measure expressed in years. It is useful for comparing population mortality patterns and long-term health trends, but it is not a personal forecast: future conditions experienced by a real cohort can change.
How to interpret it
An increase reflects lower aggregate mortality risk under the period life table. It should not be read as the age every newborn will necessarily reach.

Limitations
- It is derived from life tables based on age- and sex-specific mortality rates or from male and female series.
- Annual World Population Prospects series may be interpolated from five-year data.
- A period life table holds observed mortality patterns constant and does not reproduce a real cohort’s future experience.
