Acapulco, 
Mexico
699,888 people lived in Acapulco in 2025. It is the 768th largest of the world's 12,138 cities, and the 20th largest in Mexico.
That figure counts the whole built-up area, not the area Acapulco governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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: every dot is one of the 186 cities in Mexico in 2025, and a dot's area is how many people live there, the biggest being Mexico City. The ringed dot in colour is Acapulco; 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, Acapulco covered 136 km², and buildings, roads and other built-up land covered 31 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown to 2.7 times its size, and its people are 6.5 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 Mexico
Its share of Mexico
Of every 1,000 people in Mexico in 2025, 5 lived in Acapulco, which is 699,888 people.
How to read this: 1,000 squares stand for everyone in Mexico, one square for every 1,000th person. Count the coloured ones and you have Acapulco's share; the grey remainder live somewhere else in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Acapulco 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 Acapulco publishes about itself: how the figures here are put together.
