Miami, 
United States
2,912,486 people lived in Miami in 2025. It is the 170th largest of the world's 12,138 cities, and the 7th largest in the United States.
That figure counts the whole built-up area, not the area Miami governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Miami grew
Where Miami had 10 people in 1975, it had 56.2 in 2025.
On the UN's projection it will have 3.3 million people in 2050. It passed a million people between 1975 and 1980.
projected (after 2025) · how sure the UN is: high moderate low
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: every dot is one of the 348 cities in the United States in 2025, and a dot's area is how many people live there, the biggest being New York City. The ringed dot in colour is Miami; 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, Miami covered 1,019 km², and buildings, roads and other built-up land covered 286 km² of it. That is 98 m² of built-up land for each person, about a square 10 by 10 metres. Since 1975, its built-up land has grown to 4 times its size, and its people are 5.6 times 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 the United States
Its share of the United States
Of every 1,000 people in the United States in 2025, 8 lived in Miami, which is 2.9 million people.
How to read this: 1,000 squares, one for every 1,000th person in the United States; the coloured squares live in Miami. The grey rest live in other cities, in towns or in the countryside.

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