Demba, 
Democratic Republic of the Congo
248,191 people lived in Demba in 2025. It is the 2355th largest of the world's 12,138 cities, and the 36th largest in the Democratic Republic of the Congo.
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 Demba's own can differ widely. What counts as a city here.

projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: the Democratic Republic of the Congo and its 223 cities in 2025, each a dot whose area is its number of people (the largest is Kinshasa). Demba is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Demba covered 18 km², and buildings, roads and other built-up land covered 2.6 km² of it. That is 10 m² of built-up land for each person, about a square 3 by 3 metres. Since 1985, its built-up land has grown by 86%, and its people are 4.5 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 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 Demba, which is 248,191 people.
How to read this: shrink the Democratic Republic of the Congo to 1,000 people and this is what you get. The coloured squares are the ones who would live in Demba; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Demba are the UN's own, at five-year steps: an estimate for each of 1985 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 Demba publishes about itself: how the figures here are put together.
