Wien
2,031,326 people lived in Vienna in 2025. It is the 242nd largest of the world's 12,138 cities, and the largest in Austria, where it is the capital.
That figure counts the whole built-up area, not the area Vienna governs, so it may be far from the number the city publishes about itself. How the UN measures a city.
In its own language: Wien.

How Vienna grew
Where Vienna had 10 people in 1975, it had 13 in 2025.
On the UN's projection it will have 2.0 million people in 2050.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Vienna through your family’s years
Put in the years your family were born. You’ll see how many people lived in Vienna in each of those years, and when each of them turned 30.

Where it is
How to read this: Austria and its 8 cities in 2025, each a dot whose area is its number of people. Vienna is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Vienna covered 321 km², and buildings, roads and other built-up land covered 81 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 56%, and its people have grown by 30%.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.
Of every 100 people in Austria
Its share of Austria
Of every 100 people in Austria in 2025, 22 lived in Vienna, which is 2.0 million people.
How to read this: 100 squares stand for everyone in Austria, one square for every 100th person. Count the coloured ones and you have Vienna's share; the grey remainder live somewhere else in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Vienna are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Vienna publishes about itself: how the figures here are put together.
