Ponnani, 
India
2,409,567 people lived in Ponnani in 2025. It is the 205th largest of the world's 12,138 cities, and the 29th largest in India.
That figure counts the whole built-up area, not the area Ponnani 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: 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.

Where it is
How to read this: Ponnani is the dot in colour with a ring around it. The grey dots are the other cities of India in 2025, 2,054 in all, led by New Delhi, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Ponnani covered 721 km², and buildings, roads and other built-up land covered 46 km² of it. That is 19 m² of built-up land for each person, about a square 4 by 4 metres. Since 1980, its built-up land has grown to 21.8 times its size, and its people are 13.1 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 100 people in India
Its share of India
Of every 1,000 people in India in 2025, 2 lived in Ponnani, which is 2.4 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 Ponnani's share; the grey remainder live somewhere else in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Ponnani 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 Ponnani publishes about itself: how the figures here are put together.
