Austria Population

Austria is the world's 99th most populous country, home to about 9.1 million people in 2026. A country of Western Europe, its trajectory to 2100 is governed by how births, deaths and migration play out. It packs in roughly 110 people per square kilometre.

The peak is already behind Austria: its population maxed out at about 9.1 million near 2023 and is contracting. By 2050 the UN expects around 8.7 million people, and by 2100 about 7.4 million.

The median age is set to climb from about 43 today to roughly 49 by 2100, while life expectancy, near 82 years, keeps rising. An older population gradually reshapes the labour force, pension systems and healthcare demand.

With fertility near 1.32, just under the 2.1 replacement mark, natural increase is fading. Net inward migration adds to the population each year and partly offsets the low birth rate.

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