Tunisia Population

With roughly 12.4 million people as of 2026, Tunisia ranks 80th in the world by population. Set in Northern Africa, its demographic path this century turns on the balance of births, deaths and migration. It packs in roughly 80 people per square kilometre.

Growth continues for Tunisia until around 2052, the year its population is set to crest at about 13.1 million. From there a slow fall takes it to roughly 10.7 million by century's end.

Fertility sits at about 1.82 births per woman, below the replacement level of roughly 2.1, so without migration the population would eventually shrink.

The median age is set to climb from about 33 today to roughly 51 by 2100, even as life expectancy improves from about 77 years. A rising median age means fewer working-age people supporting each retiree over time.

The trajectory above is the UN's medium scenario. Wars, policy shifts, economic change and migration can all move the numbers, but the broad shape, growth followed by an eventual peak, is robust across the main variants.
