Strasbourg, 
France
398,175 people lived in Strasbourg in 2025. It is the 1424th largest of the world's 12,138 cities, and the 9th largest in France.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Strasbourg's own can differ widely. What counts as a city here.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

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

Where it is
How to read this: France and its 71 cities in 2025, each a dot whose area is its number of people (the largest is Paris). Strasbourg 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, Strasbourg covered 93 km², and buildings, roads and other built-up land covered 23 km² of it. That is 57 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown by 33%, and its people have grown by 22%.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in France
Its share of France
Of every 1,000 people in France in 2025, 6 lived in Strasbourg, which is 398,175 people.
How to read this: 1,000 squares stand for everyone in France, one square for every 1,000th person. Count the coloured ones and you have Strasbourg'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 Strasbourg 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 Strasbourg publishes about itself: how the figures here are put together.
