Mendoza, 
Argentina
1,027,849 people lived in Mendoza in 2025. It is the 495th largest of the world's 12,138 cities, and the 4th largest in Argentina.
That figure counts the whole built-up area, not the area Mendoza governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Mendoza grew
Count 10 people in Mendoza in 1975 and the same count gives 22 in 2025.
On the UN's projection it will have 1.1 million people in 2050. It passed a million people between 2015 and 2020.
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: Argentina and its 77 cities in 2025, each a dot whose area is its number of people (the largest is Buenos Aires). Mendoza 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, Mendoza covered 208 km², and buildings, roads and other built-up land covered 67 km² of it. That is 65 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 2.4 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.
Of every 100 people in Argentina
Its share of Argentina
Of every 100 people in Argentina in 2025, 2 lived in Mendoza, which is 1.0 million people.
How to read this: 100 squares stand for everyone in Argentina, one square for every 100th person. Count the coloured ones and you have Mendoza's share; the grey remainder live somewhere else in the country.

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