If the world were 100 people

About 8.19 billion people live on Earth. Shrink them to 100: each dot below stands for about 81.9 million real people.

Where they live

Which countries

India and China together make up 35 of the 100.

City and countryside

Each country decides for itself what counts as a city, so this is a rough picture.

Rich and poor countries

These are World Bank groups of countries by income per person. Every country has both rich and poor people.

Out of 100 adults:

Living away from their country of birth

For adults we take each country’s share and weight it by its whole population: our data has no age structure, so this is an approximation.

100 babies born today

Now take not everyone, but 100 babies, who are born on Earth in less than half a minute. They are spread across the world differently: most babies are born where people are younger and families are larger.

Where they are born

How many will survive

By the life tables the game builds from UN data for each country and sex, if things in each country stay as they are now:

Of the 49 girls, 11 will marry before 18 if the share of child marriage in their countries does not change.

Three of these lives in the game

The game lived 20 lives on its own, with no player, of babies whose country was drawn by lot. Here are three of them: one of the shortest, the middle one and one of the longest. They are made-up people with real odds.

Press “Be born” and the draw decides which of the 8 billion you will be. Then comes one life, year by year.

Be born

Data: the UN, the World Bank (release of October 8, 2026), WHO, UNICEF, UNESCO, the ILO and the World Happiness Report. Where the numbers come from and what in the game is real
