Bergamo, 
Italy
398,050 people lived in Bergamo in 2025. It is the 1426th largest of the world's 12,138 cities, and the 10th largest in Italy.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

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
How to read this: Italy and its 95 cities in 2025, each a dot whose area is its number of people (the largest is Naples). Bergamo 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, Bergamo covered 152 km², and buildings, roads and other built-up land covered 33 km² of it. That is 83 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown to 3.3 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.
Of every 100 people in Italy
Its share of Italy
Of every 1,000 people in Italy in 2025, 7 lived in Bergamo, which is 398,050 people.
How to read this: 1,000 squares, one for every 1,000th person in Italy; the coloured squares live in Bergamo. The grey rest live in other cities, in towns or in the countryside.

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