Ségou, 
Mali
295,589 people lived in Ségou in 2025. It is the 1962nd largest of the world's 12,138 cities, and the 3rd largest in Mali.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Ségou grew
Count 10 people in Ségou in 1975 and the same count gives 42.6 in 2025.
On the UN's projection it will have 453,467 people in 2050. It passed 250,000 people between 2015 and 2020.

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 20 cities in Mali in 2025, and a dot's area is how many people live there, the biggest being Bamako. The ringed dot in colour is Ségou; 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, Ségou covered 55 km², and buildings, roads and other built-up land covered 13 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 4.2 times its size, and its people are 4.3 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 Mali
Its share of Mali
Of every 100 people in Mali in 2025, 1 lived in Ségou, which is 295,589 people.
How to read this: shrink Mali to 100 people and this is what you get. The coloured squares are the ones who would live in Ségou; the grey ones are everybody else, in other cities, in towns and out 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 Ségou 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 Ségou publishes about itself: how the figures here are put together.
