Huangyan District, 
China
410,213 people lived in Huangyan District in 2025. It is the 1376th largest of the world's 12,138 cities, and the 256th largest in China.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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

Area and built-up land · km²
How much land it covers
In 2025, Huangyan District covered 75 km², and buildings, roads and other built-up land covered 20 km² of it. That is 49 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 16.7 times its size, and its people are 3.1 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 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 Huangyan District 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 Huangyan District publishes about itself: how the figures here are put together.
