Ghana and 
Peru, side by side
Ghana in 2026: half the people are older than 23. Peru: half are older than 32.
UN estimates for mid-2023: Ghana 33,787,914 people · Peru 33,845,617
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.

GHA × PER · families and lifetimes
Children, and how long lives last
If the birth rates of this year held for a whole lifetime, a woman in Ghana would have about 3.3 children and a woman in Peru 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 66 years in Ghana, about 78 in Peru.
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.

GHA × PER · 1950–2100 · how many
How big, and where they are heading
Ghana is the larger of the two, with about as many people as Peru: 35.7 million to 34.9 million.
Set each against its own 1950 self and Ghana's population is 7.0 times what it was in 1950, Peru's population is 4.5 times what it was in 1950.
Ghana's population is still growing in 2100. Meanwhile Peru's population is expected to peak in 2066. In 2100: 67.5 million in Ghana, 38.2 million in Peru (UN projection, medium).

GHA − PER · 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 Ghana and which is Peru, 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; Ghana is drawn in solid blue squares and Peru 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.
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.
