Ikorodu, 
Nigeria
916,166 people lived in Ikorodu in 2025. It is the 565th largest of the world's 12,138 cities, and the 19th largest in Nigeria.
Like every city on this site, Ikorodu is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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 Ikorodu; 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, Ikorodu covered 311 km², and buildings, roads and other built-up land covered 92 km² of it. That is 100 m² of built-up land for each person, about a square 10 by 10 metres. Since 1975, its built-up land has grown to 11.7 times its size, and its people are 11 times as many.
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.
Of every 100 people in Nigeria
Its share of Nigeria
Of every 1,000 people in Nigeria in 2025, 4 lived in Ikorodu, which is 916,166 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 Ikorodu; the grey ones are everybody else, in other cities, in towns and out 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 Ikorodu 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 Ikorodu publishes about itself: how the figures here are put together.
