Algeria and 
Yemen, side by side
Algeria in 2026: half the people are older than 30. Yemen: half are older than 19.
UN estimates for mid-2023: Algeria 46,164,219 people · Yemen 39,390,799
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
At today's rates, a woman in Algeria would have about 2.6 children in her lifetime. In Yemen, about 4.3. A baby born in Algeria this year can expect to live about 77 years. In Yemen, about 70.
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.

DZA × YEM · 1950–2100 · how many
How big, and where they are heading
Algeria has about 10% more people than Yemen: 48.0 million against 43.0 million.
Set each against its own 1950 self and Algeria's population is 5.3 times what it was in 1950, Yemen's population is 9.3 times what it was in 1950.
Algeria's population is expected to peak in 2090; Yemen's population is still growing in 2100. The UN expects Yemen to have more people than Algeria from 2034. In 2100: 64.5 million in Algeria, 110 million in Yemen (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 Algeria and which is Yemen, 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; Algeria is drawn in solid blue squares and Yemen 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
Every figure for Algeria and Yemen is the United Nations Population Division's, from World Population Prospects 2024: counted to 2023, and the medium projection for each year after that. Both places are taken from the same release and the same tables, which is what makes them comparable at all.
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.
This is one of 250 pairs with a page. The boxes at the top will take any other two places you want to see side by side.
