Ogu, 
Nigeria
256,345 people lived in Ogu in 2025. It is the 2278th largest of the world's 12,138 cities, and the 86th 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 Ogu's own can differ widely. What counts as a city here.

On the UN's projection it will have 478,129 people in 2050. It passed 250,000 people between 2020 and 2025. The UN first counts it as a city in 2010, when it passed 50,000 people.
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
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 Ogu; 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, Ogu covered 34 km², and buildings, roads and other built-up land covered 3.7 km² of it. That is 14 m² of built-up land for each person, about a square 4 by 4 metres. Since 2010, its built-up land has grown to 2.6 times its size, and its people are 2.6 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, 1 lived in Ogu, which is 256,345 people.
How to read this: 1,000 squares, one for every 1,000th person in Nigeria; the coloured squares live in Ogu. The grey rest live in other cities, in towns or in the countryside.

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 Ogu are the UN's own, at five-year steps: an estimate for each of 2010 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 Ogu publishes about itself: how the figures here are put together.
