Prayagraj, 
India
2,347,869 people lived in Prayagraj in 2025. It is the 210th largest of the world's 12,138 cities, and the 31st largest in India.
That figure counts the whole built-up area, not the area Prayagraj governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

Where Prayagraj had 10 people in 1975, it had 21.3 in 2025.
On the UN's projection it will have 2.6 million people in 2050.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Prayagraj through your family’s years
Put in the years your family were born. You’ll see how many people lived in Prayagraj in each of those years, and when each of them turned 30.

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). Prayagraj 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, Prayagraj covered 159 km², and buildings, roads and other built-up land covered 37 km² of it. That is 16 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 2.3 times its size, and its people are 2.1 times as many.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.
Of every 100 people in India
Its share of India
Of every 1,000 people in India in 2025, 2 lived in Prayagraj, which is 2.3 million people.
How to read this: shrink India to 1,000 people and this is what you get. The coloured squares are the ones who would live in Prayagraj; the grey ones are everybody else, in other cities, in towns and out in the country.

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