Las Vegas, 
United States
2,183,655 people lived in Las Vegas in 2025. It is the 232nd largest of the world's 12,138 cities, and the 10th largest in the United States.
That figure counts the whole built-up area, not the area Las Vegas governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

On the UN's projection it will have 2.4 million people in 2050. It passed a million people between 2000 and 2005. The UN first counts it as a city in 1995, when it passed 50,000 people.

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: Las Vegas is the dot in colour with a ring around it. The grey dots are the other cities of the United States in 2025, 348 in all, led by New York City, each drawn with an area that matches its people. Countries next door are outlines only.
Area and built-up land · km²
How much land it covers
In 2025, Las Vegas covered 703 km², and buildings, roads and other built-up land covered 232 km² of it. That is 106 m² of built-up land for each person, about a square 10 by 10 metres. Since 1995, its built-up land has grown to 16.1 times its size, and its people are 20.2 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 the United States
Its share of the United States
Of every 1,000 people in the United States in 2025, 6 lived in Las Vegas, which is 2.2 million people.
How to read this: 1,000 squares, one for every 1,000th person in the United States; the coloured squares live in Las Vegas. 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 Las Vegas are the UN's own, at five-year steps: an estimate for each of 1995 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 Las Vegas publishes about itself: how the figures here are put together.
