Hamilton, 
Canada
432,788 people lived in Hamilton in 2025. It is the 1292nd largest of the world's 12,138 cities, and the 10th largest in Canada.
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 Hamilton'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: Hamilton is the dot in colour with a ring around it. The grey dots are the other cities of Canada in 2025, 56 in all, led by Toronto, 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, Hamilton covered 132 km², and buildings, roads and other built-up land covered 32 km² of it. That is 74 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 73%, and its people have grown by 66%.
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 Canada
Its share of Canada
Of every 100 people in Canada in 2025, 1 lived in Hamilton, which is 432,788 people.
How to read this: 100 squares, one for every 100th person in Canada; the coloured squares live in Hamilton. The grey rest live in other cities, in towns or in the countryside.

How to read this: the figure in front of a name is where that city stands among the 12,138 cities the UN counted in 2025, and each bar is its people, on one scale per list. Numbers are missing where a city has fewer than 300,000 people and so has no page of its own.
Apparatus
Sources and method
The figures for Hamilton 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 Hamilton publishes about itself: how the figures here are put together.
