Volta Redonda, 
Brazil
398,107 people lived in Volta Redonda in 2025. It is the 1425th largest of the world's 12,138 cities, and the 43rd largest in Brazil.
That figure counts the whole built-up area, not the area Volta Redonda governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

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

Area and built-up land · km²
How much land it covers
In 2025, Volta Redonda covered 104 km², and buildings, roads and other built-up land covered 24 km² of it. That is 61 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown by 59%, and its people have grown by 72%.
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.
Of every 100 people in Brazil
Its share of Brazil
Of every 1,000 people in Brazil in 2025, 2 lived in Volta Redonda, which is 398,107 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 Volta Redonda'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 Volta Redonda 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 Volta Redonda publishes about itself: how the figures here are put together.
