Kaduna, 
Nigeria
1,890,448 people lived in Kaduna in 2025. It is the 266th largest of the world's 12,138 cities, and the 7th 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.

How Kaduna grew
Count 10 people in Kaduna in 1975 and the same count gives 50.4 in 2025.
On the UN's projection it will have 2.3 million people in 2050. It passed a million people between 1995 and 2000.

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: every dot is one of the 457 cities in Nigeria in 2025, and a dot's area is how many people live there, the biggest being Lagos. The ringed dot in colour is Kaduna; 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, Kaduna covered 311 km², and buildings, roads and other built-up land covered 91 km² of it. That is 48 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 4.1 times its size, and its people are 5 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 Nigeria
Its share of Nigeria
Of every 1,000 people in Nigeria in 2025, 8 lived in Kaduna, which is 1.9 million people.
How to read this: 1,000 squares, one for every 1,000th person in Nigeria; the coloured squares live in Kaduna. The grey rest live in other cities, in towns or in the countryside.

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