Kenya and Vietnam, side by side

Kenya in 2026: half the people are older than 21. Vietnam: half are older than 35.

UN estimates for mid-2023: Kenya 55,339,002 people · Vietnam 100,352,192

Kenya 58.6 million people Half are older than 21 3 in 100 are 65 or older

Vietnam 102 million people Half are older than 35 10 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.

Kenya

Children, under 15: 36
Aged 15 to 64: 61
Aged 65 and over: 3

Vietnam

Children, under 15: 22
Aged 15 to 64: 68
Aged 65 and over: 10

KEN × VNM · families and lifetimes

Children, and how long lives last

At today's rates, a woman in Kenya would have about 3.1 children in her lifetime. In Vietnam, about 1.9. Around 2.1 children per woman keeps a population the same size over time, leaving migration aside. A baby born in Kenya this year can expect to live about 64 years. In Vietnam, about 75.

Children per woman, 2026

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

Kenya 3.1

Vietnam 1.9

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.

Kenya 64 years

Vietnam 75 years

KEN × VNM · 1950–2100 · how many

How big, and where they are heading

There are 102 million people in Vietnam and 58.6 million in Kenya: about 70% more people than Kenya.

Since 1950 the two have moved differently: Kenya's population is 10.2 times what it was in 1950, while Vietnam's population is 4.1 times what it was in 1950.

Kenya's population is expected to peak in 2098; Vietnam's population is expected to peak in 2049. The UN expects Kenya to have more people than Vietnam from 2080. In 2100: 104 million in Kenya, 91.7 million in Vietnam (UN projection, medium).

KEN − VNM · 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 Vietnam, 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 Vietnam 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

Kenya and Vietnam 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.
