Liberia Population

Liberia, Africa's oldest republic, founded in 1847 by freed American slaves, is rebuilding after back-to-back civil wars that ended in 2003 and the Ebola epidemic a decade later. Its population is very young and fertility remains close to four children per woman. The projection sees today's nearly six million more than doubling by 2100.

With roughly 5.8 million people as of 2026, Liberia ranks 117th in the world by population. In Western Africa, where it lies, that future is driven by fertility, longevity and the movement of people across its borders. Population density stands at about 61 people for every square kilometre of land.

Growth continues for Liberia until around 2100, the year its population is set to crest at about 12.7 million. From there a slow fall takes it to roughly 12.7 million by century's end.

Half of Liberia is currently younger than about 19, but by 2100 the median age is projected to reach around 35, even as life expectancy improves from about 62 years. For now it remains one of the world's youngest populations, with a large generation about to reach working age. That ageing slowly changes everything from the size of the workforce to the cost of care and pensions.

With about 3.86 births per woman, Liberia still has one of the higher fertility rates in the world, driving fast expansion.

Read these numbers as the midpoint of a range. Under the UN's high and low fertility paths Liberia's 2100 population could land well above or below the figures here; the medium variant is simply the central case.
