Pakistan Population

Pakistan is the world's 5th most populous country, home to about 257 million people in 2026. A country of Southern Asia, its trajectory to 2100 is governed by how births, deaths and migration play out. It packs in roughly 336 people per square kilometre.

Pakistan is projected to keep growing until about 2100, when its population peaks at roughly 511 million before a gradual decline sets in, leaving it near 511 million by 2100. It is projected to pass the 500 million mark around 2092.

The median age is set to climb from about 20 today to roughly 37 by 2100, even as life expectancy improves from about 68 years. A rising median age means fewer working-age people supporting each retiree over time.

With about 3.55 births per woman, Pakistan still has one of the higher fertility rates in the world, driving fast expansion. Net outward migration also weighs on the total, with more people leaving than arriving.

All of this is a projection, not a prediction. The further out it runs the wider the plausible range becomes, which is why Pakistan's charts show a low-to-high band around the central line.
