Setif, 
Algeria
349,825 people lived in Setif in 2025. It is the 1636th largest of the world's 12,138 cities, and the 9th largest in Algeria.
That figure counts the whole built-up area, not the area Setif governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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.

Area and built-up land · km²
How much land it covers
In 2025, Setif covered 49 km², and buildings, roads and other built-up land covered 12 km² of it. That is 35 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 3.7 times its size, and its people are 3 times as many.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

Its share of Algeria
Of every 1,000 people in Algeria in 2025, 7 lived in Setif, which is 349,825 people.

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 Setif 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 Setif publishes about itself: how the figures here are put together.
