The world you are born into
Live a whole life in today's world. Today's statistics hold to the end.
How your country is drawn
The first picks a country by its number of births each year, the second by its population. Either way, life starts at age 0.
Length of one life
The time it takes to live to that country’s life expectancy. At 1 hour, a year passes in about 40–60 seconds. You can pause or speed up while you live.
Where you were actually born (optional) If you choose one, the life you live here is compared with the country you were really born in. It’s saved only on this device.
You can leave the settings as they are and be born right away.

Heavy moments such as child death, child marriage, conflict and illness happen here as often as the real statistics say.

Born in the same second

In the same second you are born, other babies are born all over the world. Four of them live out their lives by the same statistics, shown alongside yours. No one chose where to be born.

A pause

At 5, 15, 30, 50 and 70, time stops and asks you one question. Think about this person’s life and your own together, and leave a line if you like. At the end, you can say a few words to this person.

What comes from real data

For 141 countries: births, life expectancy by sex, infant and under-5 mortality, GDP per person (PPP), income inequality, years of schooling, university enrollment, employment in agriculture, fertility rate, maternal mortality, HIV, homicide rate, smoking rate, out-of-pocket health costs, child marriage rate and life satisfaction. The age at death comes from each country’s life tables by sex, and causes of death follow WHO and GBD patterns by region and age.

If making decisions feels like too much, start a life and turn on 'Auto mode' in the bar at the top (the ⋯ menu on phones) to simply watch. You pick a focus for each year and make choices when decisions come up about school, work, love, moving abroad or medical care. Choices change a life, but it is hard to fully escape the statistics of the place you were born. Today’s world is calculated with today’s statistics, a past world with that year’s, and the coming world with UN and other projections. Income comes from the country’s income distribution (based on the Gini index), and amounts are shown in purchasing-power (PPP) dollars and in US terms, as they would feel at US prices. Suicide also happens from the teenage years on, as often as the real statistics say, without showing how or why.

Death, illness, war, poverty, drinking and gambling, violence at home and suicide happen here as often as the real statistics say, and a past world tells of real history such as wars and mass killings. It is made for ages 15 and up.
