Weihai, 
China
589,850 people lived in Weihai in 2025. It is the 925th largest of the world's 12,138 cities, and the 168th 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 Weihai's own can differ widely. What counts as a city here.

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 Weihai; 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, Weihai covered 77 km², and buildings, roads and other built-up land covered 19 km² of it. That is 32 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 5.4 times its size, and its people are 4.2 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: 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 Weihai 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 Weihai publishes about itself: how the figures here are put together.
