Real data, honest limits.
Births, population, fertility and mortality come from UN World Population Prospects 2024, using 2023 estimates. World Bank indicators help scale economic and education conditions. Stories, choices, income rules and behavior effects are fictional game models. Missing nonessential indicators use explicitly marked regional estimates.
Annual mortality is derived from grouped life tables. Survival is preserved at closed age-group boundaries. Ages 100 and over use a constant hazard approximation, with a simulation limit of 110. This is not a medical prediction.
Income is a game baseline derived from half of GDP per capita at purchasing-power parity. It is not an observed salary. Schooling is a game model derived from secondary enrollment, not measured average years of education.
