Thoothukudi, 
India
368,221 people lived in Thoothukudi in 2025. It is the 1550th largest of the world's 12,138 cities, and the 250th largest in India.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Thoothukudi's own can differ widely. What counts as a city here.

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: India and its 2,054 cities in 2025, each a dot whose area is its number of people (the largest is New Delhi). Thoothukudi 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, Thoothukudi covered 49 km², and buildings, roads and other built-up land covered 11 km² of it. That is 29 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown by 53%, and its people have grown by 9%.
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 Thoothukudi 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 Thoothukudi publishes about itself: how the figures here are put together.
