Rizhao, 
China
481,315 people lived in Rizhao in 2025. It is the 1153rd largest of the world's 12,138 cities, and the 214th largest in China.
That figure counts the whole built-up area, not the area Rizhao governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Rizhao grew
Where Rizhao had 10 people in 1980, it had 91.8 in 2025.
On the UN's projection it will have 433,611 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: 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 Rizhao; 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, Rizhao covered 135 km², and buildings, roads and other built-up land covered 38 km² of it. That is 78 m² of built-up land for each person, about a square 9 by 9 metres. Since 1980, its built-up land has grown to 13.4 times its size, and its people are 9.2 times as many.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

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