Ado, 
Nigeria
300,622 people lived in Ado in 2025. It is the 1907th largest of the world's 12,138 cities, and the 69th largest in Nigeria.
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.

On the UN's projection it will have 548,270 people in 2050. It passed 250,000 people between 2015 and 2020. The UN first counts it as a city in 1990, when it passed 50,000 people.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: Ado 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, Ado covered 99 km², and buildings, roads and other built-up land covered 34 km² of it. That is 113 m² of built-up land for each person, about a square 11 by 11 metres. Since 1990, its built-up land has grown to 17.9 times its size, and its people are 5.9 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, 1 lived in Ado, which is 300,622 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 Ado; 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 Ado are the UN's own, at five-year steps: an estimate for each of 1990 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 Ado publishes about itself: how the figures here are put together.
