Binhai, 
China
227,533 people lived in Binhai in 2025. It is the 2582nd largest of the world's 12,138 cities, and the 452nd 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 Binhai grew
Count 10 people in Binhai in 1975 and the same count gives 8.3 in 2025 — the city lost people.
On the UN's projection it will have 212,136 people in 2050.
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
How to read this: China and its 2,082 cities in 2025, each a dot whose area is its number of people (the largest is Shanghai). Binhai is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Binhai covered 30 km², and buildings, roads and other built-up land covered 8.1 km² of it. That is 36 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.7 times its size, and its people have fallen by 17%.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.

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 Binhai 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 Binhai publishes about itself: how the figures here are put together.
