Zinder, 
Niger
740,218 people lived in Zinder in 2025. It is the 722nd largest of the world's 12,138 cities, and the 2nd largest in Niger.
Like every city on this site, Zinder is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Zinder is the dot in colour with a ring around it. The grey dots are the other cities of Niger in 2025, 35 in all, led by Niamey, 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, Zinder covered 49 km², and buildings, roads and other built-up land covered 13 km² of it. That is 17 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 3 times its size, and its people are 5.8 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 Niger
Its share of Niger
Of every 100 people in Niger in 2025, 3 lived in Zinder, which is 740,218 people.
How to read this: shrink Niger to 100 people and this is what you get. The coloured squares are the ones who would live in Zinder; the grey ones are everybody else, in other cities, in towns and out in the country.

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