Zhanghua City, 
Taiwan
461,552 people lived in Zhanghua City in 2025. It is the 1206th largest of the world's 12,138 cities, and the 6th largest in Taiwan.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Zhanghua City's own can differ widely. What counts as a city here.

How much land it covers
In 2025, Zhanghua City covered 144 km², and buildings, roads and other built-up land covered 35 km² of it. That is 75 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown to 5.2 times its size, and its people have grown by 39%.
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.

Apparatus
Sources and method
The figures for Zhanghua City 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 Zhanghua City publishes about itself: how the figures here are put together.
