Peru and Ukraine, side by side

Peru in 2026: half the people are older than 32. Ukraine: half are older than 43.

UN estimates for mid-2023: Peru 33,845,617 people · Ukraine 37,732,836

Peru 34.9 million people Half are older than 32 10 in 100 are 65 or older

Ukraine 39.5 million people Half are older than 43 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.

Peru

Children, under 15: 23
Aged 15 to 64: 67
Aged 65 and over: 10

Ukraine

Children, under 15: 13
Aged 15 to 64: 68
Aged 65 and over: 19

Children, and how long lives last

If the birth rates of this year held for a whole lifetime, a woman in Peru would have about 1.9 children and a woman in Ukraine about 1.0. Babies born this year can expect about 78 years of life in Peru and about 75 in Ukraine.

Children per woman, 2026

Each figure is one child: how many children a woman would have in her lifetime at that year’s rates.

Peru 1.9

Ukraine 1.0

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.

Peru 78 years

Ukraine 75 years

PER × UKR · 1950–2100 · how many

How big, and where they are heading

There are 39.5 million people in Ukraine and 34.9 million in Peru: about 10% more people than Peru.

Peru's population is 4.5 times what it was in 1950; Ukraine's population is 1.1 times what it was in 1950.

Peru's population is expected to peak in 2066. Meanwhile Ukraine's population peaked in 1993. The UN expects Peru to have more people than Ukraine from 2034. In 2100: 38.2 million in Peru, 15.2 million in Ukraine (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 Peru and which is Ukraine, 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; Peru is drawn in solid blue squares and Ukraine in open orange squares, so you can see whether each is ahead of the crowd, behind it or in the middle.

Sources and method

Peru and Ukraine 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.

The working behind the median age, the rounding in the “100 people” pictures and the reason the regions are kept out of the all-country views are all set out in the method.
