Data & assumptions

Real data provides the world’s background. Every individual life remains fiction.

2023 population, crude birth rates, sex ratios at birth and GDP per capita. GDP is an economic scale, not a claim about personal income.

Simulation assumptions

216 statistical areas are covered. Birthplaces are weighted by births. Family resources, game scores, health effects and illness progression use fictional game rules. Ages 100–120 use a fitted model tail, not published UN single-age estimates. The historical catalogue is selective; future stories are imagined, not predictions.
