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). Bairgachhi 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, Bairgachhi covered 61 km², and buildings, roads and other built-up land covered 3.1 km² of it. That is 21 m² of built-up land for each person, about a square 5 by 5 metres. Since 2020, its built-up land has grown to 2.6 times its size, and its people are 2.2 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.

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 Bairgachhi are the UN's own, at five-year steps: an estimate for each of 2020 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 Bairgachhi publishes about itself: how the figures here are put together.
