Ambala, 
India
615,565 people lived in Ambala in 2025. It is the 876th largest of the world's 12,138 cities, and the 136th largest in India.
That figure counts the whole built-up area, not the area Ambala 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: 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

Area and built-up land · km²
How much land it covers
In 2025, Ambala covered 96 km², and buildings, roads and other built-up land covered 23 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 2.2 times its size, and its people are 2 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.

Apparatus
Sources and method
The figures for Ambala 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 Ambala publishes about itself: how the figures here are put together.
