Kamwangi, 
Kenya
The UN expects Kamwangi to count as a city from 2040, with 57,733 people. This is a projection: in 2025 it did not yet meet the UN's rule for a city.
That figure counts the whole built-up area, not the area Kamwangi governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Kamwangi grew
Where Kamwangi had 10 people in 2040, it had 55.7 in 2050.
On the UN's projection it will have 321,457 people in 2050. On the UN's projection it passes 250,000 people between 2045 and 2050. The UN first counts it as a city in 2040, 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: Kenya and its 50 cities in 2025, each a dot whose area is its number of people (the largest is Nairobi). Kamwangi is ringed, drawn at its 2040 size, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2050, Kamwangi covered 176 km², and buildings, roads and other built-up land covered 25 km² of it. That is 76 m² of built-up land for each person, about a square 9 by 9 metres. Since 2040, its built-up land has grown to 6 times its size, and its people are 5.6 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 Kenya
Its share of Kenya
Of every 1,000 people in Kenya in 2050, 4 lived in Kamwangi, which is 321,457 people.
How to read this: 1,000 squares, one for every 1,000th person in Kenya; the coloured squares live in Kamwangi. The grey rest live in other cities, in towns or in the countryside.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Kamwangi are the UN's own, at five-year steps, every one of them projection, because the UN does not expect it to count as a city until 2040. 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 Kamwangi publishes about itself: how the figures here are put together.
