Mérida, 
Mexico
847,166 people lived in Mérida in 2025. It is the 618th largest of the world's 12,138 cities, and the 13th largest in Mexico.
Like every city on this site, Mérida is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

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
How to read this: every dot is one of the 186 cities in Mexico in 2025, and a dot's area is how many people live there, the biggest being Mexico City. The ringed dot in colour is Mérida; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Mérida covered 181 km², and buildings, roads and other built-up land covered 62 km² of it. That is 73 m² of built-up land for each person, about a square 9 by 9 metres. Since 1975, its built-up land has grown by 93%, and its people are 3 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.
Of every 100 people in Mexico
Its share of Mexico
Of every 1,000 people in Mexico in 2025, 6 lived in Mérida, which is 847,166 people.
How to read this: 1,000 squares, one for every 1,000th person in Mexico; the coloured squares live in Mérida. 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 Mérida 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 Mérida publishes about itself: how the figures here are put together.
