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 62.4 years in Sao Tome and Principe and 53.1 in Sierra Leone. People who reach age 60 can expect an additional 13.4 healthy years in Sao Tome and Principe 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 Sao Tome and Principe can expect to live to 72.6 years compared to 71 in Sierra Leone, rising to 79.5 and 77.7 at 65, and to 86.6 and 85.4 at 80 — higher than the 70.3 and 62.3 years calculated at birth.

The chart above accounts for remaining lifespan and displays total life expectancy by age and gender in Sao Tome and Principe 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 Sao Tome and Principe, the most common age of death is 79, compared to 0 in Sierra Leone. The median age of death is 74.1 in Sao Tome and Principe 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 Sao Tome and Principe and Sierra Leone more than their death rates.
