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.

Where it is

Area and built-up land · km²
How much land it covers
In 2025, Nakhon Pathom covered 72 km², and buildings, roads and other built-up land covered 17 km² of it. That is 74 m² of built-up land for each person, about a square 9 by 9 metres. Since 1990, its built-up land has grown to 3.7 times its size, and its people are 3.7 times as many.
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.

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 Nakhon Pathom are the UN's own, at five-year steps: an estimate for each of 1990 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 Nakhon Pathom publishes about itself: how the figures here are put together.
