Ambano, 
Madagascar
270,357 people lived in Ambano in 2025. It is the 2155th largest of the world's 12,138 cities, and the 3rd largest in Madagascar.
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 Ambano's own can differ widely. What counts as a city here.

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: Madagascar and its 24 cities in 2025, each a dot whose area is its number of people (the largest is Antananarivo). Ambano 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, Ambano covered 85 km², and buildings, roads and other built-up land covered 2.4 km² of it. That is 9 m² of built-up land for each person, about a square 3 by 3 metres. Since 2005, its built-up land has grown to 2 times its size, and its people have grown by 71%.
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 Madagascar
Its share of Madagascar
Of every 1,000 people in Madagascar in 2025, 8 lived in Ambano, which is 270,357 people.
How to read this: 1,000 squares, one for every 1,000th person in Madagascar; the coloured squares live in Ambano. The grey rest live in other cities, in towns or in the countryside.

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