Changshu, 
China
774,010 people lived in Changshu in 2025. It is the 687th largest of the world's 12,138 cities, and the 108th largest in China.
That figure counts the whole built-up area, not the area Changshu governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Changshu grew
For every 10 people in Changshu in 1975, there were 81.7 in 2025.
On the UN's projection it will have 715,488 people in 2050. It passed 250,000 people between 1985 and 1990.
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.

Where it is
How to read this: Changshu 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, Changshu covered 101 km², and buildings, roads and other built-up land covered 29 km² of it. That is 37 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 7.8 times its size, and its people are 8.2 times as many.
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.
Of every 100 people in China
Its share of China
Of every 1,000 people in China in 2025, 1 lived in Changshu, which is 774,010 people.
How to read this: shrink China to 1,000 people and this is what you get. The coloured squares are the ones who would live in Changshu; the grey ones are everybody else, in other cities, in towns and out in the country.

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