Hosur, 
India
420,017 people lived in Hosur in 2025. It is the 1340th largest of the world's 12,138 cities, and the 215th largest in India.
That figure counts the whole built-up area, not the area Hosur governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Hosur grew
Count 10 people in Hosur in 1975 and the same count gives 31 in 2025.
On the UN's projection it will have 492,130 people in 2050. It passed 250,000 people between 1995 and 2000.
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: 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 Hosur; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Hosur covered 80 km², and buildings, roads and other built-up land covered 17 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1980, its built-up land has grown to 16.6 times its size, and its people are 2.6 times as many.
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.

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