Changxing, 
China
301,206 people lived in Changxing in 2025. It is the 1902nd largest of the world's 12,138 cities, and the 351st 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 Changxing'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: 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: China and its 2,082 cities in 2025, each a dot whose area is its number of people (the largest is Shanghai). Changxing 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, Changxing covered 63 km², and buildings, roads and other built-up land covered 17 km² of it. That is 57 m² of built-up land for each person, about a square 8 by 8 metres. Since 1980, its built-up land has grown to 17.3 times its size, and its people have grown by 85%.
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.

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 Changxing 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 Changxing publishes about itself: how the figures here are put together.
