Tiruchirappalli, 
India
1,349,040 people lived in Tiruchirappalli in 2025. It is the 376th largest of the world's 12,138 cities, and the 59th largest in India.
That figure counts the whole built-up area, not the area Tiruchirappalli governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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). Tiruchirappalli 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, Tiruchirappalli covered 149 km², and buildings, roads and other built-up land covered 27 km² of it. That is 20 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 5.6 times its size, and its people are 2.3 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 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.
Apparatus
Sources and method
The figures for Tiruchirappalli 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 Tiruchirappalli publishes about itself: how the figures here are put together.
