Amassoma, 
Nigeria
188,265 people lived in Amassoma in 2025. It is the 3209th largest of the world's 12,138 cities, and the 111th 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 Amassoma'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: 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

Area and built-up land · km²
How much land it covers
In 2025, Amassoma covered 16 km², and buildings, roads and other built-up land covered 1.4 km² of it. That is 7 m² of built-up land for each person, about a square 3 by 3 metres. Since 2020, its built-up land has grown by 40%, and its people have grown by 23%.
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.

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