Jiangyin, 
China
637,502 people lived in Jiangyin in 2025. It is the 846th largest of the world's 12,138 cities, and the 146th largest in China.
Like every city on this site, Jiangyin is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Jiangyin grew
For every 10 people in Jiangyin in 1985, there were 81.4 in 2025.
On the UN's projection it will have 561,472 people in 2050. It passed 250,000 people between 1995 and 2000. The UN first counts it as a city in 1985, when it passed 50,000 people.

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.

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 Jiangyin; 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, Jiangyin covered 124 km², and buildings, roads and other built-up land covered 34 km² of it. That is 53 m² of built-up land for each person, about a square 7 by 7 metres. Since 1990, its built-up land has grown to 30.6 times its size, and its people are 5.5 times as many.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

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 Jiangyin are the UN's own, at five-year steps: an estimate for each of 1985 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 Jiangyin publishes about itself: how the figures here are put together.
