Bayt Sa`dan, 
Yemen
196,086 people lived in Bayt Sa`dan in 2025. It is the 3053rd largest of the world's 12,138 cities, and the 13th largest in Yemen.
That figure counts the whole built-up area, not the area Bayt Sa`dan governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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 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 Bayt Sa`dan are the UN's own, at five-year steps: an estimate for each of 2000 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 Bayt Sa`dan publishes about itself: how the figures here are put together.
