South Korea and Venezuela, side by side

Line both places up by age in 2026. In South Korea, half are older than 47; in Venezuela, half are older than 31.

UN estimates for mid-2023: South Korea 51,748,739 people · Venezuela 28,300,854

South Korea 51.6 million people Half are older than 47 21 in 100 are 65 or older

Venezuela 28.6 million people Half are older than 31 11 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.

South Korea

Children, under 15: 10
Aged 15 to 64: 69
Aged 65 and over: 21

Venezuela

Children, under 15: 24
Aged 15 to 64: 65
Aged 65 and over: 11

KOR × VEN · families and lifetimes

Children, and how long lives last

If the birth rates of this year held for a whole lifetime, a woman in South Korea would have about 0.8 children and a woman in Venezuela about 2.0. Life expectancy at birth this year: about 85 years in South Korea, about 73 in Venezuela.

Children per woman, 2026

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

South Korea 0.8

Venezuela 2.0

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.

South Korea 85 years

Venezuela 73 years

KOR × VEN · 1950–2100 · how many

How big, and where they are heading

There are 51.6 million people in South Korea and 28.6 million in Venezuela: about 80% more people than Venezuela.

South Korea's population is 2.6 times what it was in 1950; Venezuela's population is 5.2 times what it was in 1950.

South Korea's population peaked in 2020. Meanwhile Venezuela's population is expected to peak in 2057. The UN expects Venezuela to have more people than South Korea from 2078. In 2100: 21.8 million in South Korea, 28.3 million in Venezuela (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 South Korea and which is Venezuela, 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; South Korea is drawn in solid blue squares and Venezuela in open orange squares, so you can see whether each is ahead of the crowd, behind it or in the middle.

Sources and method

South Korea and Venezuela 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.

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.
