Trujillo, 
Peru
949,018 people lived in Trujillo in 2025. It is the 549th largest of the world's 12,138 cities, and the 3rd largest in Peru.
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 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: 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 Trujillo; 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, Trujillo covered 95 km², and buildings, roads and other built-up land covered 23 km² of it. That is 25 m² of built-up land for each person, about a square 5 by 5 metres. Since 1975, its built-up land has grown to 2 times its size, and its people are 3.3 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.

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