Port of Spain, 
Trinidad and Tobago
478,107 people lived in Port of Spain in 2025. It is the 1159th largest of the world's 12,138 cities, and the largest in Trinidad and Tobago, where it is the capital.
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 Port of Spain'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: one column every five years, 1975 to 2050; its height is the number of people. Hatched columns are the UN's projection. The thin strip beneath says how sure the UN is of each figure: the stronger the colour, the surer. A blank means the place was not on the UN's list of cities that year.

Where it is
How to read this: Port of Spain is the dot in colour with a ring around it. The grey dots are the other cities of Trinidad and Tobago in 2025, 3 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 of Spain covered 153 km², and buildings, roads and other built-up land covered 41 km² of it. That is 85 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 26%, and its people have grown by 17%.
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.

Apparatus
Sources and method
The figures for Port of Spain 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 of Spain publishes about itself: how the figures here are put together.
