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: Gravataí is the dot in colour with a ring around it. The grey dots are the other cities of Brazil in 2025, 356 in all, led by São Paulo, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Gravataí covered 76 km², and buildings, roads and other built-up land covered 22 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 2.3 times its size, and its people are 2.6 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 Brazil
Its share of Brazil
Of every 1,000 people in Brazil in 2025, 2 lived in Gravataí, which is 330,969 people.
How to read this: shrink Brazil to 1,000 people and this is what you get. The coloured squares are the ones who would live in Gravataí; the grey ones are everybody else, in other cities, in towns and out in the country.

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 Gravataí 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 Gravataí publishes about itself: how the figures here are put together.
