1 in 8 Billion Settings: World, Draw Mode & Pace Explained

The birth screen looks like a setup menu. It is really four different questions:

1. Which world’s statistics do you want?
2. Which population should choose the country?
3. How much real time should a life take?
4. Do you want a mirror to your own birthplace?

Only the first three change the simulation. The fourth is a comparison. Here is what each one does, and which combinations are worth trying.

The world: Today, The past, The future, Any world

Today

Today is the default. The life starts now and the current statistics hold to the end. A child born in India in this mode grows up with India’s current life expectancy, child mortality, income distribution and schooling, not the India of 1980.

This is the cleanest first run because the numbers in the birth card match the numbers you can look up on the game’s country pages.

The past

The past lets you choose a birth year from 1950 to 2025. The life starts in that year and runs through what actually happened after it, using that period’s statistics. The game’s own copy says a past world tells of real history, including wars and mass killings.

A past life is not simply “today with older clothes”. Child mortality is higher, schooling is shorter, income is lower, and the country may not have the institutions that exist now. The same country can be a completely different gamble in 1960 and 2020.

The future

The future starts now and runs into projections from the UN and other sources. It is the speculative mode: the early years use today’s statistics, and the later years follow the projection path rather than a fixed present.

Use it if you want to see how a life would unfold if the projections hold. Do not read a future life as a forecast of the real world; it is a simulation built on a particular set of assumptions.

Any world

Any world lets the game choose the setting. It is useful for variety and for players who have already done Today and Past. It is a poor first choice because you cannot compare the life to a known baseline.

The draw: Babies born now vs The 8 billion alive now

This is the setting players misunderstand most often.

Babies born now

The country is drawn in proportion to the number of babies born in each country per year. The game’s table sums to about 131.9 million births in 2023. India alone is 17.60% of that table — about one in six. China is 6.75%, Nigeria 5.69%, Pakistan 5.22%.

This is the default. It answers the question: if I were a baby being born right now, where would I probably be born?

The 8 billion alive now

The country is drawn in proportion to population. This answers a different question: if I picked a random living person, where would they probably live?

The difference is large. China’s share of the table is much bigger by population than by births. Nigeria’s is much bigger by births than by population. A country with a young and growing population is over-represented in the birth draw; a country with an older population is over-represented in the population draw.

What the draw does not do

• It does not draw uniformly from 172 countries. If it did, every country would be 0.58%.
• It does not draw uniformly from 8 billion people.
• It does not use your real birthplace, your IP address, your browser language or your account.
• It does not change when you pay. There is no paid re-roll.

The optional “where you were actually born” field is a comparison, not an input. In the build we checked, the game guessed a country from the browser language and showed it as a guess; you can change it or turn it off.

The pace: 30, 60 or 90 minutes

The pace setting is the time it takes to reach the country’s life expectancy. It is not the age at death. This is the single most important sentence on this page.

• About 30 minutes — a short session. Good for a first look or a classroom.
• About 1 hour — the default. One game year is about 40–60 seconds at 1×.
• About 1.5 hours — a slower, more immersive life. One game year is about 60–90 seconds.

At 16× speed, those become roughly 2.5–4 seconds per year at the one-hour setting. The speed control is separate from the pace setting. Pace sets the target; speed changes how fast you move through it.

If you want the full arithmetic, the pace calculator does it for any country. The short version: a life that ends at life expectancy takes about pace ÷ speed minutes. A 60-minute life at 16× is about 3.75 minutes before pauses.

The optional field: Where you were actually born

This field exists for comparison. If you set it, the birth card shows the simulated child next to a child born in the same second in your country. It compares life expectancy, under-5 mortality, expected years of schooling and GDP per person.

It is stored on your device only. It does not change the draw, the family, the country or the ending. It is not an account and it does not follow you to another browser unless you move your lives.

Gentle mode, frightening scenes and classroom mode

The live build shows a Leave out frightening scenes control on the birth screen. The developer’s own pages also describe a classroom mode for teaching.

They are not the same thing:

• Leave out frightening scenes is a presentation switch on the birth screen. It changes what the game shows; it is not the same thing as classroom mode.
• Classroom mode is a separate entry screen. It removes some of the heaviest material, disables posting and payments, and restricts the life to the present world. It has its own teacher guide and a class-code system.

The classroom mode guide covers the teacher side in detail. For a solo first life, the default screen is fine; use the lighter switch if you know the heavy material will distract you.

Recommended combinations

What settings do not change

• The rules of the simulation.
• The focus options available at each stage.
• The status bars and their effects.
• The death draw.
• The keepsake price or what it unlocks.

The settings choose the world you enter. They do not give you a better character, a safer life, or a higher chance of a good ending. That is the point.
