Cameroon and 
Nepal, side by side
Line both places up by age in 2026. In Cameroon, half are older than 19; in Nepal, half are older than 27.
UN estimates for mid-2023: Cameroon 28,372,687 people · Nepal 29,694,614
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
Cameroon is at about 4.1 children for each woman, at this year's rates; Nepal is at about 1.9. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. Life expectancy at birth this year: about 65 years in Cameroon, about 71 in Nepal.
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.

CMR × NPL · 1950–2100 · how many
How big, and where they are heading
Cameroon has about as many people as Nepal: 30.6 million against 29.6 million.
Cameroon's population is 7.1 times what it was in 1950; Nepal's population is 3.5 times what it was in 1950.
Looking ahead: Cameroon's population is still growing in 2100, and Nepal's population is expected to peak in 2067. In 2100: 88.9 million in Cameroon, 31.8 million in Nepal (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 Cameroon and which is Nepal, 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; Cameroon is drawn in solid blue squares and Nepal 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 Cameroon and Nepal 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.
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.
250 comparisons have a page of their own; any other two places can be compared from the boxes at the top.
