Jundiaí, 
Brazil
465,531 people lived in Jundiaí in 2025. It is the 1193rd largest of the world's 12,138 cities, and the 38th largest in Brazil.
That figure counts the whole built-up area, not the area Jundiaí governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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

Area and built-up land · km²
How much land it covers
In 2025, Jundiaí covered 115 km², and buildings, roads and other built-up land covered 31 km² of it. That is 66 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 2.4 times its size, and its people are 2.6 times as many.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Jundiaí 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 Jundiaí publishes about itself: how the figures here are put together.
