Bayannur, 
China
291,787 people lived in Bayannur in 2025. It is the 1990th largest of the world's 12,138 cities, and the 366th 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 Bayannur's own can differ widely. What counts as a city here.

How Bayannur grew
Count 10 people in Bayannur in 1980 and the same count gives 31.6 in 2025.
On the UN's projection it will have 289,736 people in 2050. It passed 250,000 people between 1990 and 1995. The UN first counts it as a city in 1980, when it passed 50,000 people.
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: 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 Bayannur; 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, Bayannur covered 44 km², and buildings, roads and other built-up land covered 14 km² of it. That is 49 m² of built-up land for each person, about a square 7 by 7 metres. Since 1980, its built-up land has grown to 2.5 times its size, and its people are 3.2 times as many.
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 Bayannur are the UN's own, at five-year steps: an estimate for each of 1980 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 Bayannur publishes about itself: how the figures here are put together.
