Hechuan, 
China
295,189 people lived in Hechuan in 2025. It is the 1966th largest of the world's 12,138 cities, and the 362nd largest in China.
That figure counts the whole built-up area, not the area Hechuan governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Hechuan grew
Count 10 people in Hechuan in 1975 and the same count gives 7 in 2025 — the city lost people.
On the UN's projection it will have 256,025 people in 2050.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 2,082 cities in China in 2025, and a dot's area is how many people live there, the biggest being Shanghai. The ringed dot in colour is Hechuan; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Hechuan covered 19 km², and buildings, roads and other built-up land covered 4.3 km² of it. That is 15 m² of built-up land for each person, about a square 4 by 4 metres. Since 1980, its built-up land has grown to 3.9 times its size, and its people have fallen by 34%.
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: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Hechuan 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 Hechuan publishes about itself: how the figures here are put together.
