Pakistan and United States, side by side

Line both places up by age in 2026. In Pakistan, half are older than 22; in the United States, half are older than 40.

UN estimates for mid-2023: Pakistan 247,504,496 people · United States 343,477,335

Pakistan 259 million people Half are older than 22 4 in 100 are 65 or older

United States 349 million people Half are older than 40 19 in 100 are 65 or older

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.

Compare shapes Compare sizes

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.

Pakistan

Children, under 15: 36
Aged 15 to 64: 60
Aged 65 and over: 4

United States

Children, and how long lives last

If the birth rates of this year held for a whole lifetime, a woman in Pakistan would have about 3.4 children and a woman in the United States about 1.6. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. A baby born in Pakistan this year can expect to live about 68 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.

Pakistan 3.4

United States 1.6

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.

Pakistan 68 years

United States 80 years

PAK × USA · 1950–2100 · how many

How big, and where they are heading

There are 349 million people in the United States and 259 million in Pakistan: about 30% more people than Pakistan.

Pakistan's population is 7.2 times what it was in 1950; the United States' population is 2.3 times what it was in 1950.

Looking ahead: Pakistan's population is still growing in 2100, and the United States' population is still growing in 2100. The UN expects Pakistan to have more people than the United States from 2053. In 2100: 511 million in Pakistan, 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 Pakistan 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; Pakistan 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.

Sources and method

Pakistan 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.

For how the median age is derived, why “100 people” can read a person high or low, and what the all-country pictures do and do not count, see the method.
