Bettiah, 
India
535,979 people lived in Bettiah in 2025. It is the 1032nd largest of the world's 12,138 cities, and the 163rd largest in India.
Like every city on this site, Bettiah is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Bettiah grew
Count 10 people in Bettiah in 1975 and the same count gives 40.8 in 2025.
On the UN's projection it will have 743,558 people in 2050. It passed 250,000 people between 2000 and 2005.
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: every dot is one of the 2,054 cities in India in 2025, and a dot's area is how many people live there, the biggest being New Delhi. The ringed dot in colour is Bettiah; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Bettiah covered 101 km², and buildings, roads and other built-up land covered 8.0 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 7.3 times its size, and its people are 4.1 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.

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