Sagar, 
India
587,471 people lived in Sagar in 2025. It is the 928th largest of the world's 12,138 cities, and the 142nd largest in India.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Sagar's own can differ widely. What counts as a city here.

How Sagar grew
Count 10 people in Sagar in 1975 and the same count gives 24.6 in 2025.
On the UN's projection it will have 666,693 people in 2050. It passed 250,000 people between 1975 and 1980.
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.

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 Sagar; 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, Sagar covered 56 km², and buildings, roads and other built-up land covered 8.7 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 5.1 times its size, and its people are 2.5 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 Sagar 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 Sagar publishes about itself: how the figures here are put together.
