Gamboru, 
Nigeria
376,374 people lived in Gamboru in 2025. It is the 1506th largest of the world's 12,138 cities, and the 56th largest in Nigeria.
That figure counts the whole built-up area, not the area Gamboru governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

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). Gamboru 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, Gamboru covered 25 km², and buildings, roads and other built-up land covered 3.6 km² of it. That is 10 m² of built-up land for each person, about a square 3 by 3 metres. Since 1975, its built-up land has grown to 3.6 times its size, and its people are 4.6 times as many.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.
Of every 100 people in Nigeria
Its share of Nigeria
Of every 1,000 people in Nigeria in 2025, 2 lived in Gamboru, which is 376,374 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 Gamboru's share; the grey remainder live somewhere else in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Gamboru 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 Gamboru publishes about itself: how the figures here are put together.
