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.

How to read this: every dot is one of the 2,054 cities in India in 2025, and a dot's area is how many people live there, the biggest being New Delhi. The ringed dot in colour is Asansol; the grey dots are the rest. The outlines around them are neighbouring countries.

In 2025, Asansol covered 243 km², and buildings, roads and other built-up land covered 30 km² of it. That is 10 m² of built-up land for each person, about a square 3 by 3 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.

Of every 1,000 people in India in 2025, 2 lived in Asansol, which is 2.9 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 Asansol's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.

The figures for Asansol 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 Asansol publishes about itself: how the figures here are put together.
