Juliaca, 
Peru
306,990 people lived in Juliaca in 2025. It is the 1875th largest of the world's 12,138 cities, and the 11th largest in Peru.
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 Juliaca's own can differ widely. What counts as a city here.

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 43 cities in Peru in 2025, and a dot's area is how many people live there, the biggest being Lima. The ringed dot in colour is Juliaca; 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, Juliaca covered 44 km², and buildings, roads and other built-up land covered 14 km² of it. That is 44 m² of built-up land for each person, about a square 7 by 7 metres. Since 1980, its built-up land has grown to 2.8 times its size, and its people are 4.7 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Peru
Its share of Peru
Of every 1,000 people in Peru in 2025, 9 lived in Juliaca, which is 306,990 people.
How to read this: 1,000 squares stand for everyone in Peru, one square for every 1,000th person. Count the coloured ones and you have Juliaca'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 Juliaca are the UN's own, at five-year steps: an estimate for each of 1980 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 Juliaca publishes about itself: how the figures here are put together.
