Matongo, 
Burundi
The UN expects Matongo to count as a city from 2035, with 118,597 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 Matongo'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: 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.

Burundi · every city · 2025
Where it is
How to read this: Burundi and its 12 cities in 2025, each a dot whose area is its number of people (the largest is Bujumbura). Matongo is ringed, drawn at its 2035 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, Matongo covered 224 km², and buildings, roads and other built-up land covered 13 km² of it. That is 29 m² of built-up land for each person, about a square 5 by 5 metres. Since 2035, its built-up land has grown to 4.3 times its size, and its people are 3.8 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 Burundi
Its share of Burundi
Of every 100 people in Burundi in 2050, 2 lived in Matongo, which is 452,604 people.
How to read this: 100 squares stand for everyone in Burundi, one square for every 100th person. Count the coloured ones and you have Matongo's share; the grey remainder live somewhere else in the country.

Cities of a similar size
In Burundi, 2025
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 Matongo 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 2035. 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 Matongo publishes about itself: how the figures here are put together.
