Tianshui, 
China
511,831 people lived in Tianshui in 2025. It is the 1085th largest of the world's 12,138 cities, and the 198th largest in China.
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 Tianshui's own can differ widely. What counts as a city here.

How Tianshui grew

On the UN's projection it will have 469,079 people in 2050. It passed 250,000 people between 1990 and 1995.

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
How to read this: Tianshui 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, Tianshui covered 47 km², and buildings, roads and other built-up land covered 10 km² of it. That is 20 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 2.6 times its size, and its people are 4.7 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 Tianshui 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 Tianshui publishes about itself: how the figures here are put together.
