Honghuagang, 
China
1,062,992 people lived in Honghuagang in 2025. It is the 483rd largest of the world's 12,138 cities, and the 70th 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 Honghuagang's own can differ widely. What counts as a city here.

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 Honghuagang; 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, Honghuagang covered 111 km², and buildings, roads and other built-up land covered 18 km² of it. That is 17 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 4.6 times its size, and its people are 4.9 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 Honghuagang, which is 1.1 million people.
How to read this: 1,000 squares, one for every 1,000th person in China; the coloured squares live in Honghuagang. The grey rest live in other cities, in towns or in the countryside.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Honghuagang 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 Honghuagang publishes about itself: how the figures here are put together.
