Dehradun, 
India
1,219,198 people lived in Dehradun in 2025. It is the 421st largest of the world's 12,138 cities, and the 68th largest in India.
Like every city on this site, Dehradun is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Dehradun grew
For every 10 people in Dehradun in 1975, there were 34 in 2025.
On the UN's projection it will have 1.5 million people in 2050. It passed a million people between 2010 and 2015.
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: Dehradun is the dot in colour with a ring around it. The grey dots are the other cities of India in 2025, 2,054 in all, led by New Delhi, 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, Dehradun covered 170 km², and buildings, roads and other built-up land covered 40 km² of it. That is 33 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 6 times its size, and its people are 3.4 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 India
Its share of India
Of every 1,000 people in India in 2025, 1 lived in Dehradun, which is 1.2 million people.
How to read this: 1,000 squares stand for everyone in India, one square for every 1,000th person. Count the coloured ones and you have Dehradun's share; the grey remainder live somewhere else in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Dehradun 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 Dehradun publishes about itself: how the figures here are put together.
