Tool 01

What are the odds your life starts in a given country?

The game draws a country from a weighted table, not a uniform list. Pick a country to see its weight, or run a batch of draws and watch the top of the table dominate.

One country Run a draw

The draw tool simulates the game’s weighted country pick. It does not play a life.

India 17.60% of births · about 1 in 6

Life expectancy 72.0 years · under-5 deaths 2.8% · GDP per person $8,871.

Shares are the game’s published shares within its 172-country table, based on UN World Population Prospects 2024 births. They are not a uniform 1-in-172 lottery. The calculator models the “Babies born now” setting; the game’s other setting, “The 8 billion alive now”, uses population instead and is not calculated here.

How the calculator works

Each country has a share of the game’s 172-country birth table. The calculator turns that share into a probability, picks a random number, and walks down the table until the cumulative weight passes the number. That is the same shape as the game’s weighted draw.

The “1 in N” line is the reciprocal of the share. India at 17.60% is 1 ÷ 0.176 = 5.68, which the game rounds to 1 in 6. The calculator shows both the precise value and the game’s rounded label so you can see the difference.

The batch draw is independent each time. It does not remove a country after it appears, and it does not try to match the exact expected counts. A batch of 10 can be wildly unrepresentative; a batch of 1,000 is usually closer.

Try this

Run 10 draws, then 1,000. The 10-draw batch is the experience of a single player: clustered, surprising and easy to misread. The 1,000-draw batch is the table: stable, top-heavy and much less dramatic.

What is not modelled

The calculator does not model the population draw, the family, the era, the character’s choices or the death draw. It models one step: which country the weight selects.

Questions about the calculator

Does this calculator use the game’s real weights?

It uses the 172-country birth shares published on the game’s official country table, snapshotted on 27 October 2026. It does not connect to the game or change its draw.

Why does India appear so often?

India is 17.60% of the game’s birth table, about one in six. In a weighted draw, the largest share appears most often. The calculator is designed to make that visible.

Does the calculator include The 8 billion alive now mode?

No. The calculator models the babies-born-now weights, which are the shares published in the 172-country table. The population mode uses a different denominator, and the game does not publish a second full table for it.

Is the draw in the calculator random?

Yes. It uses the browser’s cryptographic random number generator and the published shares. A run of the same country is possible; that is what a weighted random draw looks like.
