Dujiangyan, 
China
342,467 people lived in Dujiangyan in 2025. It is the 1671st largest of the world's 12,138 cities, and the 304th largest in China.
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 Dujiangyan's own can differ widely. What counts as a city here.

How Dujiangyan grew
Count 10 people in Dujiangyan in 1990 and the same count gives 48.9 in 2025.
On the UN's projection it will have 287,163 people in 2050. It passed 250,000 people between 2000 and 2005. The UN first counts it as a city in 1990, when it passed 50,000 people.
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.

Where it is
How to read this: every dot is one of the 2,082 cities in China in 2025, and a dot's area is how many people live there, the biggest being Shanghai. The ringed dot in colour is Dujiangyan; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Dujiangyan covered 66 km², and buildings, roads and other built-up land covered 14 km² of it. That is 41 m² of built-up land for each person, about a square 6 by 6 metres. Since 1990, its built-up land has grown to 6.3 times its size, and its people are 4.9 times as many.
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.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Dujiangyan are the UN's own, at five-year steps: an estimate for each of 1990 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 Dujiangyan publishes about itself: how the figures here are put together.
