Piura, 
Peru
471,521 people lived in Piura in 2025. It is the 1177th largest of the world's 12,138 cities, and the 7th 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: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

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 Piura; 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, Piura covered 73 km², and buildings, roads and other built-up land covered 19 km² of it. That is 40 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.6 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 Piura 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 Piura publishes about itself: how the figures here are put together.
