How these figures work

These are inherited game estimates. Individual observation years and primary-source provenance are unverified. Values describe this simulation dataset, not current official national statistics or a personal forecast.

Sources (Read in English) · JSON

Country annual birth weight ÷ sum of covered annual birth weights. Population and birth weights have different denominators.

The country draw uses annual birth weights in the bundled game dataset. Population mode instead uses population weights. Neither mode predicts your real life.
