Euclid, 
United States
290,669 people lived in Euclid in 2025. It is the 1998th largest of the world's 12,138 cities, and the 65th largest in the United States.
This is the UN's built-up area, drawn from satellite pictures and census maps rather than from the city limits, and the two can be a long way apart. The rule behind it.

How Euclid grew
Where Euclid had 10 people in 1975, it had 5.2 in 2025, fewer than it started with.
On the UN's projection it will have 210,936 people in 2050. The UN's figures for Euclid fall from 557,124 in 1975 to 210,936 in 2050. The UN rates its own confidence in the 1975 figure as high: cities are counted from census maps, and where those are old or coarse the figures are least certain.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Euclid through your family’s years
Put in the years your family were born. You’ll see how many people lived in Euclid in each of those years, and when each of them turned 30.

Where it is
How to read this: the United States and its 348 cities in 2025, each a dot whose area is its number of people (the largest is New York City). Euclid is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Euclid covered 151 km², and buildings, roads and other built-up land covered 32 km² of it. That is 110 m² of built-up land for each person, about a square 11 by 11 metres. Since 1975, its built-up land has shrunk by 16%, and its people have fallen by 48%.
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, 1 lived in Euclid, which is 290,669 people.
How to read this: shrink the United States to 1,000 people and this is what you get. The coloured squares are the ones who would live in Euclid; the grey ones are everybody else, in other cities, in towns and out in the country.

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