Bumbo, 
Uganda
The UN expects Bumbo to count as a city from 2030, with 73,224 people. This is a projection: in 2025 it did not yet meet the UN's rule for a city.
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 Bumbo's own can differ widely. What counts as a city here.

How Bumbo grew
Count 10 people in Bumbo in 2030 and the same count gives 47.3 in 2050.
On the UN's projection it will have 346,289 people in 2050. On the UN's projection it passes 250,000 people between 2040 and 2045. The UN first counts it as a city in 2030, when it passed 50,000 people.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: Uganda and its 27 cities in 2025, each a dot whose area is its number of people (the largest is Kampala). Bumbo is ringed, drawn at its 2030 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, Bumbo covered 161 km², and buildings, roads and other built-up land covered 15 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 2030, its built-up land has grown to 5.8 times its size, and its people are 4.7 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 Uganda
Its share of Uganda
Of every 1,000 people in Uganda in 2050, 4 lived in Bumbo, which is 346,289 people.
How to read this: 1,000 squares, one for every 1,000th person in Uganda; the coloured squares live in Bumbo. 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 Bumbo 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 2030. 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 Bumbo publishes about itself: how the figures here are put together.
