Oruro, 
Bolivia
347,830 people lived in Oruro in 2025. It is the 1643rd largest of the world's 12,138 cities, and the 4th largest in Bolivia.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Oruro grew
Count 10 people in Oruro in 1975 and the same count gives 31.4 in 2025.
On the UN's projection it will have 419,927 people in 2050. It passed 250,000 people between 2010 and 2015.
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: Oruro is the dot in colour with a ring around it. The grey dots are the other cities of Bolivia in 2025, 12 in all, led by La Paz, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Oruro covered 71 km², and buildings, roads and other built-up land covered 20 km² of it. That is 56 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 4.4 times its size, and its people are 3.1 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.
Of every 100 people in Bolivia
Its share of Bolivia
Of every 100 people in Bolivia in 2025, 3 lived in Oruro, which is 347,830 people.
How to read this: 100 squares, one for every 100th person in Bolivia; the coloured squares live in Oruro. The grey rest live in other cities, in towns or in the countryside.

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