Mexico and 
United States, side by side
In 2026, half of the people in Mexico are older than 31. In the United States, half are older than 40.
UN estimates for mid-2023: Mexico 129,739,759 people · United States 343,477,335
How to read this: each pyramid stacks a place’s people by age — babies at the bottom, the oldest at the top, men on the left and women on the right. A wide bottom means many children; a wide top means many older people.
Each bar is a share of its own place’s people, so a small country and a large one can be read side by side.

If each place were 100 people
Shrink each population to 100 people and count them. Dots are children under 15, filled squares are people aged 15 to 64, and open squares are people 65 and over. The picture follows the year slider above.

Children, and how long lives last
If the birth rates of this year held for a whole lifetime, a woman in Mexico would have about 1.9 children and a woman in the United States about 1.6. A baby born in Mexico this year can expect to live about 76 years. In the United States, about 80.
Children per woman, 2026
Each figure is one child: how many children a woman would have in her lifetime at that year’s rates.
The dashed line at 2.1 is about what it takes for each generation to replace the one before it, leaving migration aside.
How long a newborn can expect to live, 2026
Each block is ten years of life, if the death rates of that year stayed the same all life long.

MEX × USA · 1950–2100 · how many
How big, and where they are heading
There are 349 million people in the United States and 133 million in Mexico: about three times as many people as Mexico.
Set each against its own 1950 self and Mexico's population is 4.8 times what it was in 1950, the United States' population is 2.3 times what it was in 1950.
Mexico's population is expected to peak in 2058; the United States' population is still growing in 2100. In 2100: 130 million in Mexico, 421 million in the United States (UN projection, medium).

Which ages each place has more of
Each column is a year and each row an age, from babies at the bottom to 100 at the top. The shade of a cell shows which place has more of its people at that age — the key beside the picture tells you which shade is Mexico and which is the United States, and the in-between shade means the same. Because it compares shares, a small place and a large one can be compared fairly.

Where they sit among all countries
Every country in the world, every year from 1950 to 2100. The grey cloud shows where most countries are; Mexico is drawn in solid blue squares and the United States in open orange squares, so you can see whether each is ahead of the crowd, behind it or in the middle.

Apparatus
Sources and method
Mexico and United States are drawn here from one source and one release: the UN Population Division's World Population Prospects 2024, counted through 2023 and projected on its medium variant after that. Two places read off the same tables can be set against each other; two read off different tables cannot.
How the median age and the “100 people” pictures are worked out, and why the pictures of every country leave the regions out: how the figures here are put together.
