Nigeria

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: Biliri 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, Biliri covered 35 km², and buildings, roads and other built-up land covered 4.9 km² of it. That is 21 m² of built-up land for each person, about a square 5 by 5 metres. Since 1980, its built-up land has grown to 4.1 times its size, and its people are 3.9 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 Biliri, which is 232,398 people.
How to read this: 1,000 squares stand for everyone in Nigeria, one square for every 1,000th person. Count the coloured ones and you have Biliri's share; the grey remainder live somewhere else in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Biliri are the UN's own, at five-year steps: an estimate for each of 1980 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 Biliri publishes about itself: how the figures here are put together.
