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 67.1 years in Brunei and 64 in Iran. People who reach age 60 can expect an additional 16.1 healthy years in Brunei and 14.8 in Iran.

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 Brunei can expect to live to 77.2 years compared to 80 in Iran, rising to 81.5 and 82.9 at 65, and to 87.3 and 87.3 at 80 — higher than the 75.8 and 78.2 years calculated at birth.

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

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 Brunei, the most common age of death is 83, compared to 83 in Iran. The median age of death is 79.2 in Brunei and 81.8 in Iran, 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 Brunei and Iran more than their death rates.
