Basti, 
India
450,449 people lived in Basti in 2025. It is the 1236th largest of the world's 12,138 cities, and the 195th largest in India.
That figure counts the whole built-up area, not the area Basti 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: Basti 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, Basti covered 48 km², and buildings, roads and other built-up land covered 6.9 km² of it. That is 15 m² of built-up land for each person, about a square 4 by 4 metres. Since 1975, its built-up land has grown to 5.8 times its size, and its people have grown by 77%.
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 Basti 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 Basti publishes about itself: how the figures here are put together.
