Bauchi, 
Nigeria
642,082 people lived in Bauchi in 2025. It is the 841st largest of the world's 12,138 cities, and the 29th largest in Nigeria.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Bauchi's own can differ widely. What counts as a city here.

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 Bauchi; 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, Bauchi covered 110 km², and buildings, roads and other built-up land covered 28 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 5.2 times its size, and its people are 3.7 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.

Its share of Nigeria

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