Takamatsu, 
Japan
340,478 people lived in Takamatsu in 2025. It is the 1678th largest of the world's 12,138 cities, and the 25th largest in Japan.
That figure counts the whole built-up area, not the area Takamatsu governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Takamatsu grew
Count 10 people in Takamatsu in 1975 and the same count gives 33.2 in 2025.
On the UN's projection it will have 261,492 people in 2050. It passed 250,000 people between 1990 and 1995.
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: Takamatsu is the dot in colour with a ring around it. The grey dots are the other cities of Japan in 2025, 137 in all, led by Tokyo, 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, Takamatsu covered 159 km², and buildings, roads and other built-up land covered 38 km² of it. That is 112 m² of built-up land for each person, about a square 11 by 11 metres. Since 1975, its built-up land has grown to 3.1 times its size, and its people are 3.3 times as many.
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 1,000 people in Japan in 2025, 3 lived in Takamatsu, which is 340,478 people.
How to read this: 1,000 squares, one for every 1,000th person in Japan; the coloured squares live in Takamatsu. The grey rest live in other cities, in towns or in the countryside.

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