Agadez, 
Niger
335,322 people lived in Agadez in 2025. It is the 1712th largest of the world's 12,138 cities, and the 5th largest in Niger.
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 Agadez's own can differ widely. What counts as a city here.

How Agadez grew
Where Agadez had 10 people in 1975, it had 50.3 in 2025.
On the UN's projection it will have 568,590 people in 2050. It passed 250,000 people between 2010 and 2015.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: Niger and its 35 cities in 2025, each a dot whose area is its number of people (the largest is Niamey). Agadez is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Agadez covered 28 km², and buildings, roads and other built-up land covered 5.5 km² of it. That is 16 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 3.9 times its size, and its people are 5 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, 1 lived in Agadez, which is 335,322 people.
How to read this: 100 squares stand for everyone in Niger, one square for every 100th person. Count the coloured ones and you have Agadez's share; the grey remainder live somewhere else in the country.

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