That figure counts the whole built-up area, not the area Caxias do Sul governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

Where it is
How to read this: every dot is one of the 356 cities in Brazil in 2025, and a dot's area is how many people live there, the biggest being São Paulo. The ringed dot in colour is Caxias do Sul; the grey dots are the rest. The outlines around them are neighbouring countries.

How much land it covers
In 2025, Caxias do Sul covered 85 km², and buildings, roads and other built-up land covered 23 km² of it. That is 59 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 3 times its size, and its people are 3.4 times as many.

Apparatus
Sources and method
The figures for Caxias do Sul 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 Caxias do Sul publishes about itself: how the figures here are put together.
