Jiangyang, 
China
452,500 people lived in Jiangyang in 2025. It is the 1232nd largest of the world's 12,138 cities, and the 232nd largest in China.
Like every city on this site, Jiangyang is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Jiangyang grew
Count 10 people in Jiangyang in 1975 and the same count gives 17.8 in 2025.
On the UN's projection it will have 388,550 people in 2050.

How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: Jiangyang is the dot in colour with a ring around it. The grey dots are the other cities of China in 2025, 2,082 in all, led by Shanghai, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Jiangyang covered 60 km², and buildings, roads and other built-up land covered 8.9 km² of it. That is 20 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 7.4 times its size, and its people have grown by 78%.
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 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 Jiangyang 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 Jiangyang publishes about itself: how the figures here are put together.
