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 64 years in Iran and 62.4 in Sao Tome and Principe. People who reach age 60 can expect an additional 14.8 healthy years in Iran and 13.4 in Sao Tome and Principe.

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 Iran can expect to live to 80 years compared to 72.6 in Sao Tome and Principe, rising to 82.9 and 79.5 at 65, and to 87.3 and 86.6 at 80 — higher than the 78.2 and 70.3 years calculated at birth.

The chart above accounts for remaining lifespan and displays total life expectancy by age and gender in Iran and Sao Tome and Principe.

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 Iran, the most common age of death is 83, compared to 79 in Sao Tome and Principe. The median age of death is 81.8 in Iran and 74.1 in Sao Tome and Principe, 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 Iran and Sao Tome and Principe more than their death rates.
