Huaiyin District, 
China
1,349,827 people lived in Huaiyin District in 2025. It is the 375th largest of the world's 12,138 cities, and the 58th largest in China.
That figure counts the whole built-up area, not the area Huaiyin District governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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: 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 Huaiyin District; 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, Huaiyin District covered 137 km², and buildings, roads and other built-up land covered 35 km² of it. That is 26 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 3.7 times its size, and its people are 3.9 times as many.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.
Of every 100 people in China
Its share of China
Of every 1,000 people in China in 2025, 1 lived in Huaiyin District, which is 1.3 million people.

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