Fukuoka, 
Japan
2,225,078 people lived in Fukuoka in 2025. It is the 226th largest of the world's 12,138 cities, and the 4th largest in Japan.
That figure counts the whole built-up area, not the area Fukuoka governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

projected (after 2025) · how sure the UN is: high moderate low
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.

Fukuoka through your family’s years
Put in the years your family were born. You’ll see how many people lived in Fukuoka in each of those years, and when each of them turned 30.

Where it is
How to read this: Japan and its 137 cities in 2025, each a dot whose area is its number of people (the largest is Tokyo). Fukuoka 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, Fukuoka covered 449 km², and buildings, roads and other built-up land covered 124 km² of it. That is 56 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 55%, and its people have grown by 19%.
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.
Of every 100 people in Japan
Its share of Japan
Of every 100 people in Japan in 2025, 2 lived in Fukuoka, which is 2.2 million people.
How to read this: 100 squares stand for everyone in Japan, one square for every 100th person. Count the coloured ones and you have Fukuoka'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 Fukuoka 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 Fukuoka publishes about itself: how the figures here are put together.
