Bumba, 
Democratic Republic of the Congo
216,429 people lived in Bumba in 2025. It is the 2728th largest of the world's 12,138 cities, and the 43rd largest in the Democratic Republic of the Congo.
That figure counts the whole built-up area, not the area Bumba governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Bumba grew
Count 10 people in Bumba in 1975 and the same count gives 19 in 2025.
On the UN's projection it will have 310,304 people in 2050. On the UN's projection it passes 250,000 people between 2030 and 2035.
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: Bumba is the dot in colour with a ring around it. The grey dots are the other cities of the Democratic Republic of the Congo in 2025, 223 in all, led by Kinshasa, 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, Bumba covered 33 km², and buildings, roads and other built-up land covered 6.1 km² of it. That is 28 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2 times its size, and its people have grown by 90%.
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 the Democratic Republic of the Congo
Its share of the Democratic Republic of the Congo
Of every 1,000 people in the Democratic Republic of the Congo in 2025, 2 lived in Bumba, which is 216,429 people.
How to read this: 1,000 squares, one for every 1,000th person in the Democratic Republic of the Congo; the coloured squares live in Bumba. 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 Bumba 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 Bumba publishes about itself: how the figures here are put together.
