Dongtai, 
China
409,015 people lived in Dongtai in 2025. It is the 1380th largest of the world's 12,138 cities, and the 257th largest in China.
That figure counts the whole built-up area, not the area Dongtai governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Dongtai grew
Where Dongtai had 10 people in 1985, it had 73.7 in 2025.
On the UN's projection it will have 381,806 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.
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: Dongtai 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, Dongtai covered 56 km², and buildings, roads and other built-up land covered 12 km² of it. That is 30 m² of built-up land for each person, about a square 6 by 6 metres. Since 1985, its built-up land has grown to 4.6 times its size, and its people are 7.4 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.

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