Aligarh, 
India
1,729,663 people lived in Aligarh in 2025. It is the 283rd largest of the world's 12,138 cities, and the 42nd largest in India.
Like every city on this site, Aligarh is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: India and its 2,054 cities in 2025, each a dot whose area is its number of people (the largest is New Delhi). Aligarh 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, Aligarh covered 111 km², and buildings, roads and other built-up land covered 27 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 3.1 times its size, and its people are 2.4 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.
Of every 100 people in India
Its share of India
Of every 1,000 people in India in 2025, 1 lived in Aligarh, which is 1.7 million people.
How to read this: 1,000 squares, one for every 1,000th person in India; the coloured squares live in Aligarh. The grey rest live in other cities, in towns or in the countryside.

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