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, under 15: 24
Aged 15 to 64: 73

Children, and how long lives last

Saudi Arabia is at about 2.3 children for each woman, at this year's rates; Ukraine is at about 1.0. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. Babies born this year can expect about 79 years of life in Saudi Arabia 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.

Saudi Arabia 2.3

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.

Saudi Arabia 79 years

Ukraine 75 years

SAU × UKR · 1950–2100 · how many

How big, and where they are heading

There are 39.5 million people in Ukraine and 35.2 million in Saudi Arabia: about 10% more people than Saudi Arabia.

Set each against its own 1950 self and Saudi Arabia's population is 20.6 times what it was in 1950, Ukraine's population is 1.1 times what it was in 1950.

Saudi Arabia's population is still growing in 2100; Ukraine's population peaked in 1993. The UN expects Saudi Arabia to have more people than Ukraine from 2032. In 2100: 71.0 million in Saudi Arabia, 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 Saudi Arabia 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; Saudi Arabia 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

Saudi Arabia 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.

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.
