India
557,803 people lived in Kalyanpur in 2025. It is the 984th largest of the world's 12,138 cities, and the 154th largest in India.
Like every city on this site, Kalyanpur is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Kalyanpur grew
Count 10 people in Kalyanpur in 2000 and the same count gives 61.8 in 2025.
On the UN's projection it will have 828,893 people in 2050. It passed 250,000 people between 2005 and 2010. The UN first counts it as a city in 2000, when it passed 50,000 people.

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: India and its 2,054 cities in 2025, each a dot whose area is its number of people (the largest is New Delhi). Kalyanpur 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, Kalyanpur covered 243 km², and buildings, roads and other built-up land covered 11 km² of it. That is 19 m² of built-up land for each person, about a square 4 by 4 metres. Since 2000, its built-up land has grown to 7.7 times its size, and its people are 6.2 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.

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