Life Expectancy in Nigeria vs Sierra Leone (1950-2025)

Remaining life expectancy by current age

Life expectancy is often mistaken for the average lifespan of an adult. An adult has already survived early-age mortality causes and is expected to have a longer lifespan than calculated from birth.

The life expectancy from current ages in Nigeria vs Sierra Leone: 67.1 years vs 70.9 at 30, 77.2 vs 77.6 at 65, 85.2 vs 85.4 at 80 — significantly higher than the 54.8 vs 62.2 years calculated at birth.

The chart and table below account for the remaining lifespan and display total life expectancy by age and gender in Nigeria and Sierra Leone.

Odds of living to age in Nigeria vs Sierra Leone

The chart below shows the odds of living to all ages starting from birth. Of the newborn cohort, 55.7% in Nigeria and 70% in Sierra Leone are expected to survive till at least 60 years old, 39.3% and 51.7% will live to 70 years or older, 16.9% and 23% to 80+ years, and 2.22% and 3.18% will live past 90 years old.

For longevity rates starting from an age other than 0, use the probability of survival to an age calculator provided above.

The chart above shows the number of deaths by age and gender per a 100,000 cohort of newborns, illustrating the distribution of expected mortality throughout life.

Note that the graph above does not represent rates per 100,000 population, as this would be skewed by age distribution and reveal more about Nigeria and Sierra Leone demographics than the death rate. It also does not represent rates per 100,000 people in an age group, as this would be just the probability of death.
