Riwoto, 
South Sudan
330,053 people lived in Riwoto in 2025. It is the 1740th largest of the world's 12,138 cities, and the 4th largest in South Sudan.
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 Riwoto's own can differ widely. What counts as a city here.

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.

Area and built-up land · km²
How much land it covers
In 2025, Riwoto covered 47 km², and buildings, roads and other built-up land covered 0.4 km² of it.

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 Riwoto are the UN's own, at five-year steps: an estimate for each of 2015 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 Riwoto publishes about itself: how the figures here are put together.
