Nepal and 
Niger, side by side
Nepal in 2026: half the people are older than 27. Niger: half are older than 17.
UN estimates for mid-2023: Nepal 29,694,614 people · Niger 26,159,867
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.

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
Nepal is at about 1.9 children for each woman, at this year's rates; Niger is at about 5.6. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. A baby born in Nepal this year can expect to live about 71 years. In Niger, about 62.
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.

NPL × NER · 1950–2100 · how many
How big, and where they are heading
There are 29.6 million people in Nepal and 28.8 million in Niger: about as many people as Niger.
Nepal's population is 3.5 times what it was in 1950; Niger's population is 11.1 times what it was in 1950.
Looking ahead: Nepal's population is expected to peak in 2067, and Niger's population is still growing in 2100. The UN expects Niger to have more people than Nepal from 2028. In 2100: 31.8 million in Nepal, 90.8 million in Niger (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 Nepal and which is Niger, 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; Nepal is drawn in solid blue squares and Niger 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
Nepal and Niger 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.
250 comparisons have a page of their own; any other two places can be compared from the boxes at the top.
