Port-au-Prince, 
Haiti
1,868,268 people lived in Port-au-Prince in 2025. It is the 270th largest of the world's 12,138 cities, and the largest in Haiti, where it is the capital.
Like every city on this site, Port-au-Prince is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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: Port-au-Prince is the dot in colour with a ring around it. The grey dots are the other cities of Haiti in 2025, 21 in all, 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, Port-au-Prince covered 275 km², and buildings, roads and other built-up land covered 73 km² of it. That is 39 m² of built-up land for each person, about a square 6 by 6 metres. Since 1975, its built-up land has grown to 2.5 times its size, and its people have grown by 93%.
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 Haiti
Its share of Haiti
Of every 100 people in Haiti in 2025, 16 lived in Port-au-Prince, which is 1.9 million people.
How to read this: shrink Haiti to 100 people and this is what you get. The coloured squares are the ones who would live in Port-au-Prince; 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 Port-au-Prince 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 Port-au-Prince publishes about itself: how the figures here are put together.
