Yiyang, 
China
703,724 people lived in Yiyang in 2025. It is the 761st largest of the world's 12,138 cities, and the 128th largest in China.
Like every city on this site, Yiyang is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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). Yiyang 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, Yiyang covered 114 km², and buildings, roads and other built-up land covered 19 km² of it. That is 27 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 5.5 times its size, and its people are 2.5 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.
Of every 100 people in China
Its share of China
Of every 1,000 people in China in 2025, 1 lived in Yiyang, which is 703,724 people.
How to read this: 1,000 squares stand for everyone in China, one square for every 1,000th person. Count the coloured ones and you have Yiyang's share; the grey remainder live somewhere else in the country.

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