Chiclayo, 
Peru
620,622 people lived in Chiclayo in 2025. It is the 868th largest of the world's 12,138 cities, and the 4th largest in Peru.
Like every city on this site, Chiclayo is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Chiclayo grew
Count 10 people in Chiclayo in 1975 and the same count gives 27 in 2025.
On the UN's projection it will have 694,544 people in 2050. It passed 250,000 people between 1975 and 1980.
projected (after 2025) · how sure the UN is: high moderate low
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 Chiclayo; 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, Chiclayo covered 52 km², and buildings, roads and other built-up land covered 16 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 by 72%, and its people are 2.7 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 Peru
Its share of Peru
Of every 100 people in Peru in 2025, 2 lived in Chiclayo, which is 620,622 people.
How to read this: shrink Peru to 100 people and this is what you get. The coloured squares are the ones who would live in Chiclayo; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Chiclayo 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 Chiclayo publishes about itself: how the figures here are put together.
