Parma, 
United States
322,420 people lived in Parma in 2025. It is the 1780th largest of the world's 12,138 cities, and the 59th largest in the United States.
That figure counts the whole built-up area, not the area Parma governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Parma grew
Count 10 people in Parma in 1975 and the same count gives 5.9 in 2025 — the city lost people.
On the UN's projection it will have 223,421 people in 2050. The UN's figures for Parma fall from 546,317 in 1975 to 223,421 in 2050. The UN rates its own confidence in the 1975 figure as moderate: 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: 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: Parma 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, Parma covered 159 km², and buildings, roads and other built-up land covered 39 km² of it. That is 120 m² of built-up land for each person, about a square 11 by 11 metres. Since 1975, its built-up land is about the same size, and its people have fallen by 41%.
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 Parma, which is 322,420 people.
How to read this: 1,000 squares, one for every 1,000th person in the United States; the coloured squares live in Parma. 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 Parma 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 Parma publishes about itself: how the figures here are put together.
