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.

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). Kahemba is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.

In 2025, Kahemba covered 12 km², and buildings, roads and other built-up land covered 2.5 km² of it. That is 12 m² of built-up land for each person, about a square 3 by 3 metres. Since 1975, its built-up land has grown by 32%, and its people have grown by 28%.

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 1,000 people in the Democratic Republic of the Congo in 2025, 2 lived in Kahemba, which is 215,825 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 Kahemba. 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.

The figures for Kahemba 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 Kahemba publishes about itself: how the figures here are put together.
