Kasama, 
Zambia
233,587 people lived in Kasama in 2025. It is the 2517th largest of the world's 12,138 cities, and the 7th largest in Zambia.
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 Kasama's own can differ widely. What counts as a city here.

How Kasama grew
Where Kasama had 10 people in 1990, it had 34.3 in 2025.
On the UN's projection it will have 388,569 people in 2050. On the UN's projection it passes 250,000 people between 2025 and 2030. The UN first counts it as a city in 1990, when it passed 50,000 people.
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: every dot is one of the 33 cities in Zambia in 2025, and a dot's area is how many people live there, the biggest being Lusaka. The ringed dot in colour is Kasama; 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, Kasama covered 43 km², and buildings, roads and other built-up land covered 9.9 km² of it. That is 42 m² of built-up land for each person, about a square 7 by 7 metres. Since 1990, its built-up land has grown to 2.3 times its size, and its people are 3.4 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Zambia
Its share of Zambia
Of every 100 people in Zambia in 2025, 1 lived in Kasama, which is 233,587 people.
How to read this: shrink Zambia to 100 people and this is what you get. The coloured squares are the ones who would live in Kasama; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Kasama are the UN's own, at five-year steps: an estimate for each of 1990 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 Kasama publishes about itself: how the figures here are put together.
