Kenya and 
Sudan, side by side
Line both places up by age in 2026. In Kenya, half are older than 21; in Sudan, half are older than 20.
UN estimates for mid-2023: Kenya 55,339,002 people · Sudan 50,042,790
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.

KEN × SDN · families and lifetimes
Children, and how long lives last
Kenya is at about 3.1 children for each woman, at this year's rates; Sudan is at about 4.1. Life expectancy at birth this year: about 64 years in Kenya, about 67 in Sudan.
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.
Hatched marks are UN projections (medium variant), not measurements.
KEN × SDN · 1950–2100 · how many
How big, and where they are heading
Kenya is the larger of the two, with about 10% more people than Sudan: 58.6 million to 53.3 million.
Since 1950 the two have moved differently: Kenya's population is 10.2 times what it was in 1950, while Sudan's population is 8.6 times what it was in 1950.
Kenya's population is expected to peak in 2098; Sudan's population is still growing in 2100. The UN expects Sudan to have more people than Kenya from 2047. In 2100: 104 million in Kenya, 137 million in Sudan (UN projection, medium).

KEN − SDN · 1950–2100 · every age
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 Kenya and which is Sudan, 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; Kenya is drawn in solid blue squares and Sudan 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
Both sides of this comparison come from the UN Population Division's World Population Prospects 2024 — the same release, the same tables, counted to 2023 and projected beyond it on the medium variant. That shared origin is what a comparison rests on.
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.
