Genoa, 
Italy
532,509 people lived in Genoa in 2025. It is the 1042nd largest of the world's 12,138 cities, and the 6th 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 Genoa grew
Where Genoa had 10 people in 1975, it had 7.2 in 2025, fewer than it started with.
On the UN's projection it will have 484,009 people in 2050.

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.

Genoa through your family’s years
Put in the years your family were born. You’ll see how many people lived in Genoa in each of those years, and when each of them turned 30.

Where it is
How to read this: every dot is one of the 95 cities in Italy in 2025, and a dot's area is how many people live there, the biggest being Naples. The ringed dot in colour is Genoa; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Genoa covered 102 km², and buildings, roads and other built-up land covered 19 km² of it. That is 36 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown by 38%, and its people have fallen by 28%.
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 Italy
Its share of Italy
Of every 1,000 people in Italy in 2025, 9 lived in Genoa, which is 532,509 people.
How to read this: shrink Italy to 1,000 people and this is what you get. The coloured squares are the ones who would live in Genoa; the grey ones are everybody else, in other cities, in towns and out 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 Genoa 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 Genoa publishes about itself: how the figures here are put together.
