Finland Population

Finland is the world's 120th most populous country, home to about 5.6 million people in 2026. A country of Northern Europe, its trajectory to 2100 is governed by how births, deaths and migration play out. It packs in roughly 19 people per square kilometre.

Having topped out near 5.6 million around 2026, Finland has entered the long, slow decline now spreading across much of the world. Its population is projected to fall to roughly 5.4 million by 2050 and about 4.6 million by 2100.

At about 1.29 births per woman, Finland has one of the world's lowest fertility rates, well under the replacement level of around 2.1. Immigration is a meaningful contributor, bringing in more people than leave in a typical year.

The median age is set to climb from about 43 today to roughly 51 by 2100, while life expectancy, near 82 years, keeps rising. That ageing slowly changes everything from the size of the workforce to the cost of care and pensions.

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, a population already past its peak, is robust across the main variants.
