Bida, 
Nigeria
421,605 people lived in Bida in 2025. It is the 1332nd largest of the world's 12,138 cities, and the 47th 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 Bida's own can differ widely. What counts as a city here.

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: Nigeria and its 457 cities in 2025, each a dot whose area is its number of people (the largest is Lagos). Bida is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Bida covered 47 km², and buildings, roads and other built-up land covered 13 km² of it. That is 30 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 3.2 times its size, and its people are 4.4 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 Bida, which is 421,605 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 Bida; 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 Bida 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 Bida publishes about itself: how the figures here are put together.
