Asaba, 
Nigeria
403,859 people lived in Asaba in 2025. It is the 1401st largest of the world's 12,138 cities, and the 51st largest in Nigeria.
That figure counts the whole built-up area, not the area Asaba governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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: Asaba is the dot in colour with a ring around it. The grey dots are the other cities of Nigeria in 2025, 457 in all, led by Lagos, 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, Asaba covered 68 km², and buildings, roads and other built-up land covered 22 km² of it. That is 55 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 6.4 times its size, and its people are 4.1 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 Nigeria
Its share of Nigeria
Of every 1,000 people in Nigeria in 2025, 2 lived in Asaba, which is 403,859 people.
How to read this: shrink Nigeria to 1,000 people and this is what you get. The coloured squares are the ones who would live in Asaba; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Asaba 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 Asaba publishes about itself: how the figures here are put together.
