Life expectancy is the average age of death for a hypothetical cohort of newborns if they experienced the age-specific mortality rates of one particular year throughout their entire lives. It's a snapshot reflecting mortality rates in a given year that does not account for any future changes in those rates.

Healthy life expectancy at birth, defined by the World Health Organization as the average number of years a person can expect to live in full health, is 73.4 years in Japan and 53.1 in Sierra Leone. People who reach age 60 can expect an additional 20.4 healthy years in Japan and 12.6 in Sierra Leone.

Life expectancy is often mistaken for the average lifespan of an adult. However, an adult has already survived the causes of early-age mortality and can expect to live longer than the figure calculated at birth.

A 30-year-old in Japan can expect to live to 85.6 years compared to 71 in Sierra Leone, rising to 87.8 and 77.7 at 65, and to 91.1 and 85.4 at 80 — higher than the 85.1 and 62.3 years calculated at birth.

The chart above accounts for remaining lifespan and displays total life expectancy by age and gender in Japan and Sierra Leone.

This chart shows the number of deaths by age up to 100 for 3 cohorts of 100,000 newborns each — male, female, and both combined — illustrating how expected mortality is distributed throughout life.

In Japan, the most common age of death is 91, compared to 0 in Sierra Leone. The median age of death is 88.1 in Japan and 70.8 in Sierra Leone, meaning only half of each cohort is expected to live past that age.

Note that this chart does not show rates per 100,000 population, as those would be skewed by age structure differences and reflect the demographics of Japan and Sierra Leone more than their death rates.
