Colombia and Uganda, side by side

In 2026, half of the people in Colombia are older than 34. In Uganda, half are older than 18.

UN estimates for mid-2023: Colombia 52,321,152 people · Uganda 48,656,602

Colombia 53.9 million people Half are older than 34 11 in 100 are 65 or older

Uganda 52.8 million people Half are older than 18 2 in 100 are 65 or older

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.

Compare shapes Compare sizes

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.

Colombia

Children, under 15: 20
Aged 15 to 64: 69
Aged 65 and over: 11

Uganda

Children, under 15: 43

Aged 65 and over: 2

Children, and how long lives last

At today's rates, a woman in Colombia would have about 1.6 children in her lifetime. In Uganda, about 4.0. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. Babies born this year can expect about 78 years of life in Colombia and about 69 in Uganda.

Children per woman, 2026

Each figure is one child: how many children a woman would have in her lifetime at that year’s rates.

Colombia 1.6

Uganda 4.0

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.

Colombia 78 years

Uganda 69 years

COL × UGA · 1950–2100 · how many

How big, and where they are heading

Colombia is the larger of the two, with about as many people as Uganda: 53.9 million to 52.8 million.

Since 1950 the two have moved differently: Colombia's population is 4.6 times what it was in 1950, while Uganda's population is 9.2 times what it was in 1950.

Colombia's population is expected to peak in 2050; Uganda's population is still growing in 2100. The UN expects Uganda to have more people than Colombia from 2028. In 2100: 47.1 million in Colombia, 121 million in Uganda (UN projection, medium).

COL − UGA · 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 Colombia and which is Uganda, 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; Colombia is drawn in solid blue squares and Uganda 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.

How the median age and the “100 people” pictures are worked out, and why the pictures of every country leave the regions out: how the figures here are put together.
