Abéché, 
Chad
443,793 people lived in Abéché in 2025. It is the 1254th largest of the world's 12,138 cities, and the 2nd largest in Chad.
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.

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: Abéché is the dot in colour with a ring around it. The grey dots are the other cities of Chad in 2025, 37 in all, led by N'Djaména, 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, Abéché covered 46 km², and buildings, roads and other built-up land covered 10 km² of it. That is 23 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 4.2 times its size, and its people are 6.8 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.

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