Campinas, 
Brazil
1,631,432 people lived in Campinas in 2025. It is the 299th largest of the world's 12,138 cities, and the 13th largest in Brazil.
Like every city on this site, Campinas is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Brazil and its 356 cities in 2025, each a dot whose area is its number of people (the largest is São Paulo). Campinas is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Campinas covered 366 km², and buildings, roads and other built-up land covered 106 km² of it. That is 65 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 6.7 times its size, and its people are 15.1 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 Brazil
Its share of Brazil
Of every 1,000 people in Brazil in 2025, 8 lived in Campinas, which is 1.6 million people.
How to read this: 1,000 squares stand for everyone in Brazil, one square for every 1,000th person. Count the coloured ones and you have Campinas'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 Campinas 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 Campinas publishes about itself: how the figures here are put together.
