Kaifeng, 
China
1,087,088 people lived in Kaifeng in 2025. It is the 473rd largest of the world's 12,138 cities, and the 68th largest in China.
Like every city on this site, Kaifeng is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Kaifeng grew
For every 10 people in Kaifeng in 1975, there were 26 in 2025.
On the UN's projection it will have 974,919 people in 2050. It passed a million people between 2015 and 2020.
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: Kaifeng is the dot in colour with a ring around it. The grey dots are the other cities of China in 2025, 2,082 in all, led by Shanghai, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Kaifeng covered 144 km², and buildings, roads and other built-up land covered 38 km² of it. That is 35 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.4 times its size, and its people are 2.6 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 Kaifeng, which is 1.1 million 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 Kaifeng'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 Kaifeng 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 Kaifeng publishes about itself: how the figures here are put together.
