Kisii, 
Kenya
200,579 people lived in Kisii in 2025. It is the 2983rd largest of the world's 12,138 cities, and the 9th largest in Kenya.
Like every city on this site, Kisii is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

On the UN's projection it will have 342,503 people in 2050. On the UN's projection it passes 250,000 people between 2030 and 2035. 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 50 cities in Kenya in 2025, and a dot's area is how many people live there, the biggest being Nairobi. The ringed dot in colour is Kisii; 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, Kisii covered 71 km², and buildings, roads and other built-up land covered 10 km² of it. That is 52 m² of built-up land for each person, about a square 7 by 7 metres. Since 1990, its built-up land has grown to 5.8 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 Kenya
Its share of Kenya
Of every 1,000 people in Kenya in 2025, 3 lived in Kisii, which is 200,579 people.
How to read this: 1,000 squares, one for every 1,000th person in Kenya; the coloured squares live in Kisii. The grey rest live in other cities, in towns or in the countryside.

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