Florence, 
Italy
430,806 people lived in Florence in 2025. It is the 1298th largest of the world's 12,138 cities, and the 9th largest in Italy.
The UN measures every city in the world the same way, by where the buildings are rather than where the boundary runs, so this figure and Florence's own can differ widely. What counts as a city here.

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.

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

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). Florence 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, Florence covered 84 km², and buildings, roads and other built-up land covered 20 km² of it. That is 47 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 63%, and its people are about as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Italy
Its share of Italy
Of every 1,000 people in Italy in 2025, 7 lived in Florence, which is 430,806 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 Florence; 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 Florence 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 Florence publishes about itself: how the figures here are put together.
