Kumasi, 
Ghana
4,297,984 people lived in Kumasi in 2025. It is the 98th largest of the world's 12,138 cities, and the 2nd largest in Ghana.
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 Kumasi's own can differ widely. What counts as a city here.

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: Kumasi is the dot in colour with a ring around it. The grey dots are the other cities of Ghana in 2025, 58 in all, led by Accra, 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, Kumasi covered 439 km², and buildings, roads and other built-up land covered 138 km² of it. That is 32 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.9 times its size, and its people are 10.3 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 Ghana
Its share of Ghana
Of every 100 people in Ghana in 2025, 12 lived in Kumasi, which is 4.3 million people.
How to read this: 100 squares, one for every 100th person in Ghana; the coloured squares live in Kumasi. The grey rest live in other cities, in towns or in the countryside.

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 Kumasi 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 Kumasi publishes about itself: how the figures here are put together.
