Tongliao, 
China
512,445 people lived in Tongliao in 2025. It is the 1083rd largest of the world's 12,138 cities, and the 197th 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 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: China and its 2,082 cities in 2025, each a dot whose area is its number of people (the largest is Shanghai). Tongliao 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, Tongliao covered 78 km², and buildings, roads and other built-up land covered 24 km² of it. That is 46 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 3.1 times its size, and its people are 2.3 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: 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 Tongliao 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 Tongliao publishes about itself: how the figures here are put together.
