Okrika, 
Nigeria
289,429 people lived in Okrika in 2025. It is the 2007th largest of the world's 12,138 cities, and the 72nd largest in Nigeria.
Like every city on this site, Okrika is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Okrika 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, Okrika covered 26 km², and buildings, roads and other built-up land covered 4.2 km² of it. That is 15 m² of built-up land for each person, about a square 4 by 4 metres. Since 1980, its built-up land has grown to 2.5 times its size, and its people are 4 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 Okrika, which is 289,429 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 Okrika; the grey ones are everybody else, in other cities, in towns and out 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 Okrika 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 Okrika publishes about itself: how the figures here are put together.
