Owo, 
Nigeria
301,931 people lived in Owo in 2025. It is the 1900th largest of the world's 12,138 cities, and the 68th largest in Nigeria.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

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). Owo 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, Owo covered 51 km², and buildings, roads and other built-up land covered 12 km² of it. That is 38 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.8 times its size, and its people are 3.5 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, 1 lived in Owo, which is 301,931 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 Owo; 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 Owo 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 Owo publishes about itself: how the figures here are put together.
