Yongkang, 
China
385,247 people lived in Yongkang in 2025. It is the 1476th largest of the world's 12,138 cities, and the 272nd largest in China.
Like every city on this site, Yongkang is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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

Area and built-up land · km²
How much land it covers
In 2025, Yongkang covered 74 km², and buildings, roads and other built-up land covered 18 km² of it. That is 45 m² of built-up land for each person, about a square 7 by 7 metres. Since 1985, its built-up land has grown to 14.6 times its size, and its people are 5.4 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 Yongkang 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 Yongkang publishes about itself: how the figures here are put together.
