Tlemcen, 
Algeria
301,980 people lived in Tlemcen in 2025. It is the 1898th largest of the world's 12,138 cities, and the 10th largest in Algeria.
That figure counts the whole built-up area, not the area Tlemcen 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.

Where it is
How to read this: Tlemcen is the dot in colour with a ring around it. The grey dots are the other cities of Algeria in 2025, 109 in all, led by Algiers, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Tlemcen covered 62 km², and buildings, roads and other built-up land covered 11 km² of it. That is 37 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 4.7 times its size, and its people are 4.1 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Algeria
Its share of Algeria
Of every 1,000 people in Algeria in 2025, 6 lived in Tlemcen, which is 301,980 people.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Tlemcen 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 Tlemcen publishes about itself: how the figures here are put together.
